Lightweight Dry Bag First Aid

Thermoplastic Urethane (TPU) is a PVC-free / PFC-free material utilized in a number of functional areas within Sea to Summit products.

It is used either an airproof barrier (sleeping mats), a waterproof barrier (dry bags, packing cubes, Folding Bucket) or a transparent layer (View Dry Bags, Accessory Cases, See Pouches).

TPU is strong and flexible (even when cold), and works well for applications such as attachment points/straps on Watercells.

Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with moisture, such as tent wall condensation.Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It does not affect the 'breathability' or the lifespan of the down and lasts through at least 20 washings. The down used in our sleeping bags is responsibly sourced.Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.

Strong and lightweight, RCS Recycled, bluesign approved 70 Denier Nylon fabric. The outer face uses a non-PFC DWR to help to shed water. The inner PU coating is waterproof (rated to 10,000mm hydrostatic head) and is colored bright white to make it easy to find your gear.

These dry bags are flexible enough to fit into awkward spaces and rugged enough for paddling and bikepacking.
