backpack shell

Body Fabric: SHELL

SHELL is a three-layer, laminated “sailcloth” material originally developed for the sails of racing boats. 

Sailcloth works well for sails and backpacks because it is durable, lightweight, and waterproof.

SHELL is 100% recycled and uses no harmful TPU, PVC, DWR, or other coatings.

The durable, water-repellent (DWR) coating is C0 meaning that it contains no fluorocarbons like PFAS/PFOA.

Unlike other laminated fabrics that use solvent-based adhesives, SHELL doesn’t contain any VOCs (volatile organic compounds).

backpack zipper


Zippers: YKK

Tortuga only uses best-in-class YKK zippers for durability, water resistance, and security.

We use PU-coated zippers for the best balance between water resistance and ease of use. For security, you'll find lockable zippers on the main compartments of our bags.

A travel backpack is only as good as its weakest component, and zippers are often the weakest parts of a bag. Cheap, low-quality zippers can distort and break. A broken zipper will ruin the backpack you invested in and trusted to travel the world with you. That’s why we only use the best zippers we can find.
