## Overview

The Sea to Summit Ultra-Sil Dry Bag Set includes three ultralight (0.07-0.09 lbs) waterproof stuff sacks (3L, 5L, 8L) made from bluesign-approved 30D Ultra-Sil Cordura ripstop nylon with a 2,000mm waterhead rating.

## Description

The Sea to Summit Ultra-Sil Dry Bag Set provides three convenient ultra-lightweight dry storage options for fast and light backpacking, bike touring, and travel. Manufactured from bluesign-approved 30D Ultra-Sil Cordura ripstop nylon, their reinforced waterproof seams are double-stitched, and tape sealed, with reinforced stitching at stress points; 2,000mm waterhead (the higher the waterhead rating, the more waterproof the fabric). A secure Hypalon roll-top closure keeps moisture out, and a patent-pending field repair buckle can be replaced in seconds with a Phillips screwdriver. The translucent fabric makes it easy to see what’s inside the bag, and the low-profile, streamlined oval shape saves space, and resists rolling. The Sea to Summit Ultra-Sil Dry Bag Set includes three dry bags: 3L (measures 6.7 x 5.5 x 8.1 inches when closed, and weighs just 0.07 pounds), 5L (measures 6.7 x 5.9 x 12.1 inches when closed, and weighs just 0.07 pounds), and 8L (measures 7.5 x 6.8 x 14.5 inches when closed, and weighs just 0.09 pounds. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.

Review: Excellent ultra-light solutions for keeping stuff dry or containing wet items. - These bags are very lightweight, waterproof, and durable. I purchased two a number of years ago and have used them on bikepacking trips for years. I originally purchased them to hold dirty or wet clothes on bike trips so that the other things in my bags wouldn't funk up. They work brilliantly for this purpose and are plenty durable for use inside backpacks or panniers. I do not think they'd be suitable for situations where they'd come into regular contact with thorns or rocks. This year my son had to use panniers that were not waterproof. We ordered 6 more (two three packs) so that his important stuff would stay dry during downpours. I have pretty much converted from other packing solutions to these. My one nit-pick is that they don't have a valve to let air out and aid in compressing the as I have seen on other heavier duty bags. That said, they are really quite easy to close in a compacted state, and adding a valve would likely increase the weight by 50% or more.
Review: The difference between dry or hypothermia. These bags work! - When keeping your items dry means the difference between success and failure, Sea to Summit has you covered. I backpack in the deep backcountry and keeping my clothing dry is the difference between warm and dry or hypothermia. Simply put, they work! I can compress the air out to conserve space in my pack and keep my items dry and that is especially important if you are a day or two from civilization.
