Sea to Summit Talus 80L Duffle Bag Overview
The Sea to Summit Talus 80L Duffle Bag is a heavy-duty expedition duffle designed for transporting large gear loads across demanding travel environments.
Built with oversized YKK zips, reinforced attachment rails and durable recycled fabrics, the Talus combines rugged construction with adaptable carry options for expedition travel, vehicle-supported adventures and extended gear hauling. Its convertible carry system lets the bag switch quickly between hand-carry and backpack-style transport, depending on the situation.
The oversized D-shaped opening provides wide access to the main compartment for easier packing and organisation, while the included storage sack converts into a packing cube for improved internal organisation during longer trips.

Materials & Construction
ReShield Fabric Construction — Recycled PVB Protection
The Talus uses Sea to Summit’s ReShield fabric construction, which incorporates recycled PVB film reclaimed from discarded vehicle windscreens. PVB (polyvinyl butyral) is the strong laminated layer normally used inside car windscreens to improve impact resistance and prevent glass shattering.
By repurposing this material into the duffle’s fabric laminate, Sea to Summit creates a construction that combines durability, weather resistance and abrasion protection while reducing landfill waste from automotive manufacturing and recycling streams.
This reinforced laminated structure helps the Talus withstand demanding expedition travel, repeated hauling and rough transport conditions without relying solely on virgin materials.
1500D Recycled Polyester — Heavy-Duty Exterior
The main body uses 1500D recycled polyester, designed to withstand demanding travel environments and repeated expedition use.
This heavyweight construction supports abrasion resistance and long-term durability during transport.
1000D Recycled Nylon Base — Reinforced Protection
A reinforced 1000D recycled nylon base improves durability in high-wear areas when the duffle is placed on rough ground, transport surfaces or expedition staging areas.
Non-PFAS Construction
The Talus is built using non-PFAS materials, meaning it avoids the use of per- and polyfluoroalkyl substances often found in traditional water-resistant outdoor fabrics and coatings.
PFAS chemicals are widely used in outdoor equipment because they provide strong water and stain resistance, but they are also known for persisting in the environment for long periods without breaking down naturally.
By removing PFAS from the Talus construction, Sea to Summit reduces the environmental impact associated with long-term chemical pollution while still maintaining the durability, weather resistance and expedition-ready performance expected from a heavy-duty duffle bag.
Features & Technologies
Convertible Carry System — Hand Carry to Backpack
The carry straps quickly convert between traditional hand-carry mode and backpack-style carry, depending on transport requirements.
Hand-carry mode works well when loading the duffle into vehicles, carrying it through airports, moving between hotels or transporting heavy gear short distances where quick access matters most. The padded grab handles on all four sides also make it easier to lift the bag into roof boxes, boats or expedition vehicles.
Backpack-style carry becomes more useful during longer walks between transport connections, carrying gear across campsites, navigating train stations or moving equipment over rough terrain where keeping both hands free improves balance and comfort.
Oversized D-Shaped Opening — Easier Packing Access
The oversized D-shaped lid with YKK #10 zips provides wide access into the main compartment for easier packing and gear retrieval.
The stiff fabric construction helps the bag maintain its shape while loading.
Hypalon Attachment Rail — Expedition Durability
The Talus features a reinforced Hypalon attachment rail that wraps around the entire duffle, creating a highly durable external structure designed for demanding expedition travel.
Hypalon is a heavy-duty synthetic rubberised material commonly used in expedition and marine equipment because it resists abrasion, moisture and repeated stress extremely well. On the Talus, this rail acts as both a reinforcement system and a series of external attachment points.
In real-world use, it allows the duffle to be securely strapped onto roof racks, boats, expedition vehicles or trailers without placing excessive strain directly on the main fabric. It also provides reliable anchor points for clipping extra gear, securing compression straps or handling the bag during rough transport conditions.
Padded Grab Handles — Multi-Angle Carrying
Padded grab handles positioned on all four sides improve handling when lifting, carrying or loading the duffle into vehicles or storage systems.
Protective Base & Lid Padding
The padded base and lid construction help protect both carried equipment and user comfort during backpack-style transport.
Convertible Storage Sack — Packing Cube Function
The included duffle storage sack converts into a packing cube, helping keep smaller items organised inside the main compartment during travel.
How does it carry?
The Talus 80L is designed to adapt across different stages of expedition travel.
Its fully removable convertible straps allow fast transition between duffle-style hand carry and backpack carry, while the padded construction improves comfort when moving heavier loads over longer distances.
