Two hard cargo cases, near-identical length, and two very different design philosophies. That is the short version of the Pelican Cargo BX255 vs Eylar SRX-175 question. Below is a spec-by-spec read of both listings, with the tradeoffs spelled out for people mounting a box on a roof rack or dropping one into a truck bed.
- Massive 175L Capacity – External: 47.2"L x 18.4"W x 17.9"H fits most full-size truck beds & roof racks; Internal: 42.5" x 12.7" x 13.2"; Weight: 38.5 lbs
- 100% Waterproof Seal – Heavy-duty rubber gasket keeps contents bone-dry in rain, mud, creek crossings, and pressure washing; protect electronics, sleeping gear, food, and more
Quick Answer
Go with the Pelican Cargo Case BX255 (Black) if interior room is the deciding factor and you want a long-term ownership story. Pelican publishes interior dimensions of 42.80" x 16.25" x 17.20" and a limited lifetime guarantee on the case itself. That is meaningfully wider and taller inside than the alternative here.
Go with the Eylar SRX-175 Overlanding Cargo Case if you want convenience features baked in at purchase. Eylar's listing specifies a gas strut lid that stays propped open, four padlock-compatible lockable latches, two removable organizer trays plus a divider, a cargo net, a built-in drain plug, and a stackable flat top/bottom design.
Here is the thing: these boxes are not competing on size. They are competing on what you get in the box and what happens years later.

Design & Build Quality
Start with the exterior dimensions, keeping in mind that an external envelope is not a mounting footprint and does not by itself establish whether a box fits your rack. Pelican gives the BX255 an exterior of 47.00" x 21.25" x 20.00" [S3]. Eylar gives the SRX-175 an exterior of 47.2"L x 18.4"W x 17.9"H [S4]. Length is within a fraction of an inch. The Pelican is the wider and taller box by roughly 2.9 inches and 2.1 inches respectively. Neither listing states crossbar spacing, permitted crossbar width, roof-mount hardware or any roof-rack fit specification, so before ordering confirm the manufacturer-approved mounting system for the case and check the full limits of your vehicle, your rack and the box together, including the empty weight of the case and mounting equipment plus the cargo you intend to carry.
Now the dimension differences. Subtracting interior from exterior leaves a difference the listings do not explain, so it does not establish wall thickness, material use or durability. The Pelican Cargo Case BX255 (Black) shows about 5 inches of width and 2.8 inches of height between its stated outer and inner dimensions [S3]. The Eylar SRX-175 Overlanding Cargo Case shows about 5.7 inches of width and 4.7 inches of height between its stated outer and inner dimensions [S4]. Eylar describes the SRX-175 as rotomolded hard case construction with an impact-resistant shell [S4]; the supplied Pelican listing does not state a molding process, so we are not going to guess at one.
The Pelican Cargo Case BX255 (Black) listing states a weight empty of 38.90 lbs [S3]. The Eylar SRX-175 Overlanding Cargo Case listing states a weight of 38.5 lbs without saying whether that figure is the empty case [S4]. Because the Eylar figure is not defined as an unloaded weight, the supplied records do not establish a like-for-like empty-weight comparison — which matters if you are working to a roof load budget. Neither listing states a lift or handling requirement, so the supplied records do not establish how many people either case takes to load onto a roof rack.
On sealing language, read carefully. Pelican's listing says weather resistant and dustproof [S3]. Eylar's says 100% waterproof seal with a heavy-duty rubber gasket, described as keeping contents bone-dry in rain, mud, creek crossings, and pressure washing [S4]. Those are not the same claim, and "weather resistant" is a deliberately narrower word than "waterproof." Both are seller claims, not independent certification. Neither listing claims submersion or an immersion rating, so if underwater use is your requirement, the supplied records do not establish it for either case.
Preferred for interior volume: Pelican Cargo Case BX255 (Black). Its stated interior is wider and taller than the SRX-175's [S3][S4]. Check Price on Amazon
Features & Functionality
Here is what each listing actually specifies.
The Eylar SRX-175 Overlanding Cargo Case ships with a stack of usability features spelled out on its listing [S4]:
- A gas strut lid that stays propped open automatically, so both hands stay free while loading.
- Four heavy-duty lockable latches, padlock-compatible (padlock sold separately).
- Two removable interior organizer trays plus a divider, and an included cargo net for top-layer retention.
- A built-in drain plug, which Eylar says doubles as an improvised cooler function when filled with ice.
- A flat top/bottom stackable design, plus reflective stickers for low-light trail visibility.
The supplied Pelican listing does not state a latch count, a lid strut, interior trays, or a drain plug. That means those specs are not in the record we have — not that Pelican never publishes them. Absence from the supplied Pelican record is not evidence the BX255 lacks those items, so the supplied records do not support a head-to-head comparison of included hardware.

Performance
"Performance" for a cargo case means three things: how much it swallows, how well it keeps water and dust out, and whether it survives the trail.
On volume, the Eylar SRX-175 Overlanding Cargo Case listing advertises a 175L capacity while giving an interior of 42.5" x 12.7" x 13.2" in the same bullet [S4]; those stated internal dimensions do not reconcile with a 175 L figure, so the case's actual capacity is not established by the supplied record and the 175L number should be treated as an unverified seller claim pending confirmation from Eylar. The Pelican Cargo Case BX255 (Black) does not state a liter figure in the supplied listing, but publishes an interior of 42.80" x 16.25" x 17.20" [S3]. On stated interior dimensions the Pelican is 3.55 inches wider and 4 inches taller at essentially the same length [S3][S4]. If you are stacking bulky sleeping gear, measure your own items against the full usable interior dimensions and the lid opening, because a stated interior height on its own does not establish that a given object fits or that either case is approved for a particular type of contents.
On ingress protection, neither listing supplies an IP rating. Pelican claims weather resistant and dustproof [S3]; Eylar claims a rubber-gasket waterproof seal that its listing describes as keeping contents bone-dry in pressure washing and creek crossings [S4]. Take both as manufacturer claims.
On durability, Pelican's listing claims extreme durability and backs the case with a limited lifetime guarantee (case only) [S3]. Eylar's listing claims an impact-resistant rotomolded shell that resists rough trails, drops, and extreme weather, with a 30-day return policy [S4]. Honestly, the warranty language is the more decision-relevant fact here: a limited lifetime guarantee on the case and a 30-day return window are different kinds of coverage entirely. The supplied Eylar SRX-175 Overlanding Cargo Case record states a 30-day return policy and does not state a warranty term, so no comparison of coverage length is established by the records we have.
A relative durability ranking between these two is not established by the supplied data. Neither listing publishes a drop-test standard, a load rating, or a UV rating.
Price & Value
Both are listed on Amazon and pricing moves, so check the current figure on each before deciding. What the specs let you say about value is this: Eylar bundles the trays, divider, cargo net and reflective stickers into the purchase [S4], while Pelican's cross-bed truck mounting requires the Pelican Cargo Cross-Bed Mount sold separately [S3]. Padlocks for the Eylar's four latches are also sold separately [S4].
On the other side of the ledger, the Pelican Cargo Case BX255 (Black) listing states a limited lifetime guarantee covering the case only [S3]. The Eylar SRX-175 Overlanding Cargo Case listing states a 30-day return policy and no warranty term [S4]. The supplied records include no current price for either case and no Eylar warranty term, so which one is the better buy is not established here.
Pros and Limitations
Pelican Cargo Case BX255 (Black)
Strengths: the largest stated interior of the two at 42.80" x 16.25" x 17.20"; a limited lifetime guarantee on the case; heavy duty lay-flat handles, tie-down plates and a mounting kit interface plate [S3].
Limitations to know: the Pelican Cargo Cross-Bed Mount for secure truck-bed mounting is sold separately; the sealing claim is "weather resistant and dustproof," not waterproof; at 21.25" wide and 20.00" tall it is the bigger exterior footprint [S3]. Only Black is named in the supplied listing.
Eylar SRX-175 Overlanding Cargo Case
Strengths: a hands-free gas strut lid, four padlock-compatible lockable latches, two removable trays plus divider and cargo net, a built-in drain plug, stackable flat top/bottom design, and four listed colors — Black, Gray, Tan, and Green [S4]. Its advertised 175L capacity is an unverified seller claim that conflicts with the same listing's stated internal dimensions of 42.5" x 12.7" x 13.2", so we do not treat it as an established spec [S4].
Limitations to know: its stated interior of 42.5" x 12.7" x 13.2" is narrower and shorter than the BX255's; the padlocks are sold separately; and Eylar's supplied listing states a 30-day return policy rather than a longer warranty term [S4].
Which Should You Buy?
You run a full-size truck bed and haul bulky, tall gear. Take the Pelican Cargo Case BX255 (Black). Its 17.20" interior height and 16.25" interior width give you more usable box than the SRX-175's 13.2" x 12.7" [S3][S4]. Pelican's listing states the case is designed to mount securely in a truck bed using the Pelican Cargo Cross-Bed Mount, sold separately; the listing does not supply an installation procedure or mounting load limits [S3]. Check Price on Amazon
You load and unload constantly, alone. Take the Eylar SRX-175 Overlanding Cargo Case. The gas strut lid is specified to stay propped open so both hands stay free, and the two removable trays plus divider and cargo net mean your small gear is not buried [S4]. Check Price on Amazon
Water crossings and pressure washing are part of the routine. The Eylar SRX-175 Overlanding Cargo Case listing claims a 100% waterproof rubber-gasket seal that keeps contents bone-dry in rain, mud, creek crossings and pressure washing [S4]; that is a listing claim, not a stated test result. Pelican's listing claims weather resistant and dustproof [S3].
You want coverage that outlasts the season. Pelican's limited lifetime guarantee applies to the case [S3]. The Eylar SRX-175 Overlanding Cargo Case record states a 30-day return policy and does not state a warranty term [S4].
You are fitting a box into a limited space. The Eylar SRX-175 Overlanding Cargo Case lists an exterior of 47.2"L x 18.4"W x 17.9"H [S4]. The Pelican Cargo Case BX255 (Black) lists an exterior of 47.00" x 21.25" x 20.00" [S3]. Neither listing states crossbar spacing, permitted crossbar width, roof-mount hardware or any roof-rack fit specification, and box height is not mounted height, so the supplied records do not establish roof-rack compatibility or overhead clearance for either case. Measure your own vehicle, rack and cover first.
You need a color other than black. Eylar lists Black, Gray, Tan and Green [S4]. The supplied Pelican record lists Black.

How We Research
This comparison was built by reading the published product records for both ASINs and comparing their stated numbers directly. The evidence used here is limited to two source types: the Amazon Creators API verified product record for each case, and the product listing feature bullets published on each Amazon listing, both retrieved September 6, 2026 [S3][S4]. Where a spec is absent from one listing, we say so rather than filling it in from another product or another variant. Nobody here handled, loaded, mounted, soaked or weighed either case.
For general guidance on consumer product safety and recalls, CPSC [S1] and USA.gov consumer protection [S2] are the appropriate authorities.
Frequently Asked Questions
The Pelican Cargo Case BX255 (Black), based on published interior dimensions. Pelican lists 42.80" x 16.25" x 17.20" [S3]; Eylar lists 42.5" x 12.7" x 13.2" [S4]. The Pelican is wider and taller inside at nearly the same length.
Is the Eylar SRX-175 actually waterproof?
Eylar's listing claims a 100% waterproof seal using a heavy-duty rubber gasket, described as keeping contents dry in rain, mud, creek crossings, and pressure washing [S4]. That is the manufacturer's own claim; the listing does not supply an independent IP rating or third-party certification.
Does the Pelican BX255 come with a truck bed mount?
No. Pelican's listing states the case is designed to mount securely in a truck bed using the Pelican Cargo Cross-Bed Mount, sold separately [S3].
Can I lock either case?
Eylar specifies four heavy-duty lockable latches that are padlock-compatible, with the padlock sold separately [S4]. The supplied Pelican listing does not state a latch count or locking provision, so that detail is not established by the record we have.
How much do these boxes weigh empty?
Pelican lists the Pelican Cargo Case BX255 (Black) at 38.90 lbs weight empty [S3]. Eylar lists a weight of 38.5 lbs for the Eylar SRX-175 Overlanding Cargo Case but does not state whether that figure is the empty case [S4], so the supplied records do not establish an empty-weight figure for it or a comparison between the two.
What warranty does each one carry?
Pelican's listing states a limited lifetime guarantee covering the case only [S3]. Eylar's listing states a 30-day return policy [S4]. No longer warranty term is given for the Eylar in the supplied record.
Do either of these stack or work as a cooler?
Eylar describes a flat top/bottom stackable design that stacks on roof racks or in truck beds, and a built-in drain plug that lets the case double as an improvised cooler when filled with ice [S4]. The supplied Pelican listing does not state a stacking or drain-plug feature.
Final Verdict
If you buy on volume and long-term coverage, the Pelican Cargo Case BX255 (Black) is the stronger case: 42.80" x 16.25" x 17.20" inside and a limited lifetime guarantee on the case [S3]. Just remember the Cross-Bed Mount is a separate purchase [S3]. Check Price on Amazon
If you buy on daily usability, the Eylar SRX-175 Overlanding Cargo Case listing specifies a gas strut lid, four lockable latches, two trays with a divider, a cargo net, a drain plug, and four color options [S4]. The supplied Pelican record does not list those fields, which is not evidence the BX255 lacks them. Check Price on Amazon
My read on the split: the Pelican is a container with a warranty behind it, and the Eylar is a system with organization built in. Confirm the manufacturer-approved mounting system and the full vehicle, rack and box limits — including empty case and equipment weight plus cargo weight — decide whether you need waterproof or weather resistant, and the choice makes itself.
Sources & Methodology
This website does not physically test or lab-test the products it writes about, and this cargo case comparison is no exception — nothing here was mounted to a vehicle, filled, submerged or dropped. What was done is a close side-by-side reading of the Amazon Creators API verified product records and the published listing feature bullets for ASIN B0C11X23R9 and ASIN B0DWZXYZWT, both retrieved on September 6, 2026, with every dimension, weight and feature claim traced back to the listing that publishes it [S3][S4]. For hard cargo boxes, that kind of specification reading answers the questions that actually decide the purchase — what exterior dimensions each listing publishes, how much fits inside, what hardware is included versus sold separately, and what coverage comes with it — while questions of long-term gasket life, real-world impact survival and finish durability would require use over time that no published spec sheet settles.
