The Chasm is designed for expedition travelers who need durable, water-resistant gear and quick access through a wide-mouth opening. The 40L size is the maximum for airline carry-on; larger models require checking. While the 900D polyester shell offers excellent abrasion resistance, the lack of a traditional shoulder strap and waist belt reduces comfort for 70L and larger versions during extended travel.

Who Fits the Chasm?
The stiff 900D material provides strong protection but requires the bag to be well-packed to maintain its shape during travel.
The Multi-Modal Commuter: BUY
- Best Fit: Travelers transitioning between aircraft overhead bins and rugged ground transport.
- Critical Limit: 40L (Maximum Carry-On Volume).
The 40L model fits in overhead compartments and under seats if not overpacked. Backpack-style straps support hands-free movement, but the absence of a waist belt is noticeable on long journeys.
The Extended Expeditionist: BUY
- Best Fit: Safari, sailing, or 2-week rugged road trips where gear protection is paramount.
- Critical Limit: 70L – 130L Volume Range.
The larger models hold enough gear for up to two weeks and withstand heavy rain and rough handling. The 900D polyester shell protects contents from dust and moisture in demanding environments.
The Ergonomic Specialist: SKIP
- Best Fit: Users with narrow shoulders or those who require a traditional single-shoulder duffel carry.
- Critical Limit: >20 lbs Static Load.
Heavy loads in the 70L and 90L models can strain the shoulders due to the lack of a waist belt or cross-body strap. The dual-handle and backpack-only options are not ideal for long walks in airports.
External Shell: 900D Polyester Durability
The 900D polyester fabric provides a high-density barrier against abrasion and environmental moisture.
| Metric | Value |
| Mention Rate | 64% (38/59) |
| Performance Status | Strength |
| Comfort Limit | Water-Resistant (Not Submersible) |
- “Material is strong, resilient, and water-resistant.” — 70L User
- “Material is SUPER STIFF. God forbid this was in any kind of cold weather.” — 40L User
The 900D construction emphasizes durability over flexibility. Its high denier count exceeds industry standards, ensuring the bag withstands rough handling and outdoor use. However, the material is stiff, prone to creasing, and less flexible in cold weather.
Geometric Profile: Tapered Depth and Padded Base
The Chasm has a unique duffel shape, with the top panel deeper than the bottom.
| Metric | Value |
| Mention Rate | 12% (7/59) |
| Performance Status | Mixed |
| Comfort Limit | Asymmetrical Packing Required |
- “Bottom of the duffel is a few inches less deep than the top of the bag.” — 70L User
- “The bottom of the bag is padded.” — 70L User
The tapered design requires packing larger items at the top to avoid space issues, as the bottom is shallower. The 70L version includes a padded base for added protection during transport.
Load Carriage: Modular Straps and Manipulation Handles
The Chasm includes multiple strap options and reinforced grab handles for easy handling.
| Metric | Value |
| Mention Rate | 58% (34/59) |
| Performance Status | Strength |
| Comfort Limit | End-to-End Extraction |
- “Carry handles at each end were also very helpful.” — 40L User
- “Side panel straps can be made longer… making the bag easy to side carry.” — 70L User
Dual-end handles and adjustable side straps make it easy to maneuver in tight spaces. Backpack mode is standard, but longer side straps allow side-carry, and reinforced handles make quick retrieval from vehicles or overhead bins easier.
Load Carriage Constraints: Ergonomic Deficiencies
Despite its versatility, the strap system lacks key weight-management features common in trekking bags.
| Metric | Value |
| Mention Rate | 15% (9/59) |
| Performance Status | Weakness |
| Comfort Limit | No Sternum/Waist Support |
- “Tampoco existe una correa para el esternón ni correa de sujeción interna.” — 30L User
- “Shoulder straps put the zipper on the inside (back side) of the duffle.” — 70L User
The Chasm does not provide the support needed for long treks. Without a sternum strap or internal hold-down straps, loads can shift, causing instability. The zipper placement against the back improves security but makes access difficult while wearing the bag. The absence of daisy-chain loops or external lashing points also limits attachment options.
Main Compartment: Wide-Mouth Aperture and Mesh Segmentation
The large lid opens fully, providing access to the entire interior and built-in organizational features.
| Metric | Value |
| Mention Rate | 30% (18/59) |
| Performance Status | Strength |
| Comfort Limit | Two-Zone Mesh Organization |
- “The standout feature of this bag is the wide opening.” — 70L User
- “Two mesh pockets inside (one smaller and one larger) for organizing.” — 70L User
The full-access top entry prevents the “black hole” effect found in many duffels. Two mesh pockets, one small and one large, help organize electronics and toiletries. The light interior fabric improves visibility in low light.
Volumetric Management: Compression and Storage
External hardware helps manage the bag’s bulk, and a secondary pouch adds versatility.
| Metric | Value |
| Mention Rate | 22% (13/59) |
| Performance Status | Strength |
| Comfort Limit | External Compression Hardware |
- “External compression straps can help reduce the bag’s size.” — 70L User
- “Stuff sack can also be used as a Diddy bag for toiletries.” — 40L User
External compression straps help reduce the stiffness of the empty 900D shell and minimize gear shifting when partially loaded. The included storage sack is often used for laundry or toiletries because the main bag is difficult to refold into its original shape.
Weather Resistance: Zipper and Fabric Seals
The Chasm uses DWR-coated fabric and strong zippers to protect against moisture.
| Metric | Value |
| Mention Rate | 25% (15/59) |
| Performance Status | Strength |
| Comfort Limit | Rain-Proof (Not Waterproof) |
- “Poured on in the rain and all my stuff inside was dry.” — 130L User
- “If you submerge for a length of time the water will penetrate the zippers.” — Scuba/River User.
The Chasm offers strong weather protection but is not fully waterproof. The 900D fabric blocks rain, but the zippers can let in water if submerged or exposed to high pressure.
Can the Chasm Hold Your Gear?
The interior is mostly rectangular but tapers toward the base, which affects how rigid items fit inside.
| Accessory or Sizing Item | Status | Technical Conflict/Result |
| Thule Compression Cubes | Fits | Optimized for internal mesh footprint |
| 14-Day Clothing Supply | Fits | Accommodated by 70L+ variants |
| Patagonia Black Hole | Fits | Thule offers stiffer material but higher weight |
| Water Bottle | Fails | No external holster or lashing point |
| Airline Under-Seat Space | Fits | 40L (when not overstuffed) |
The Chasm works well with Thule packing cubes. However, it lacks an external hydration holster and daisy-chain lashing points, limiting the attachment of items such as bottles or headphones. Compared to the Patagonia Black Hole, the Chasm is heavier and more rigid.
Is the Chasm Worth It?
The Chasm is a durable gear hauler that sacrifices some ergonomic features in favor of long-lasting materials. It performs well in situations where the bag may be tossed, stacked, or exposed to rain, as long as a traditional shoulder strap is not needed.
BUY the Chasm if:
- You require a 40L carry-on with backpack-style mobility.
- You need high-visibility identification in busy airports (Olivine/Golden Brown colors).
- You need 900D polyester protection for rugged environments, such as safaris or sailing trips.
SKIP the Chasm if:
- You require internal compression straps or external lashing points (Daisy Chains).
- You plan to travel in cold weather where the shell material becomes excessively rigid.
- You have narrow shoulders and plan to carry 70L+ loads over a 19-hour itinerary without a sternum or waist belt.
The bag becomes difficult to carry when the load exceeds 30 pounds. Without load-lifters or a hip belt, the weight is concentrated on the shoulders.
