If you want a lightweight dry bag that’s still strong and looks good, the Ultra-Sil Dry Bag from Sea to Summit is a solid choice. With the range of sizes there’s something for every situation, a small 2 litre version for your electronics or first aid kit, up to a larger size for clothing and your sleep system.
I’ve taken these on serious trips and they held up to plenty of abuse. The fabric is 30D Cordura, the seams are double-stitched and taped, and the bag closes with a waterproof Hypalon roll-top. It’s made from siliconised nylon with a PU coating for full waterproofing. This protects your sleeping gear, clothing and other kit from rain and damp.
All Sea to Summit dry bags have fully replaceable buckles, so if anything ever breaks you can simply swap it out instead of binning the whole bag.
Available in several sizes: 2, 4, 8, 13 and 20 litres. Colour: grey or blue.
