Review Summary

Really happy with these bags. Great for organizing and keeping clean my own gear and for containing the dog's things too. They are water resistant, so we use them accordingly. Sturdy, durable, great sizes, great colors, invitingly touchable material, and a great company. For reference, the photo shows STS stuff sacks too, which are also wonderful. The size of each ultra sil bag is visible on it's bottom right. The stuff sac above is the corresponding volume.

Used these bags on a recent JMT hike. The bags kept my items dry over three consecutive rainy days.

Bought a few of these to replace my not-so-waterproof stuff sacks that our down sleeping bags came in. They're durable and the seams look solid. I've run one of them under a sink and had absolutely no water come in.

Ultralight and Water-Resistant Gear Storage
This Stuff Sack offers a smart, compact way to organize your gear without adding unnecessary weight. Made from bluesign approved Ultra-Sil 30D nylon fabric, it features a PFC-free DWR finish that provides reliable water resistance while remaining eco-conscious. Whether you're hiking, camping, or traveling, this ultralight stuff sack helps keep your clothing and gear dry and neatly stowed in your pack or bag.
Built for Durability and Daily Use
Despite its featherweight design, this Sea to Summit gear sack is built to handle real-world use. Reinforced at all stress points and double-stitched for added durability, it stands up to the demands of regular outdoor adventures. The Cordura nylon fabric delivers both strength and a 2000mm hydrostatic head, offering a solid defense against moisture and abrasion. It's a practical and rugged solution for organizing and protecting your essentials.
Smart Design with Effortless Access
Featuring a tear-proof drawcord throat and a Capture Cord Lock system, the opening is both secure and easy to operate. Two super-strong Hypalon pull-tabs ensure smooth handling, even with gloves or cold hands. The slippery fabric finish and a reinforced grab handle at the base allow you to slide the sack in and out of your backpack with ease.
