Sea to Summit Ultra-Sil Stuff Sack

The Sea to Summit Ultra-Sil Stuff Sack is an ultralight yet durable solution for organizing gear inside your backpack or travel bag. Made from bluesign®-approved Ultra-Sil 30D nylon with a Non-PFC DWR finish, it offers dependable water resistance while keeping weight to an absolute minimum.

Designed with long-distance hikers in mind, these stuff sacks feature a tear-resistant drawcord throat with dual Hypalon® pull tabs and a Capture Cord Lock, making them easy to open and close—even with cold or tired hands. A reinforced grab handle at the base allows for quick removal from tightly packed backpacks, while the slippery fabric helps the sack slide in and out effortlessly.
