If you want to compress your gear for your cycling or kayaking tour while keeping it dry, the Evac Compression Dry Bag from Sea to Summit is the perfect solution. With an uncompressed size of 35 liters, it can hold your warm sleeping bag, your tent without poles, or all your clothing. The advantage over regular stuff sacks is that the contents in the Evac Compression Dry Bag stay truly dry thanks to the waterproof outer material with C0 treatment, the roll closure, and the sealed seams, while also being able to be packed into a compact size. The durable 70D outer material with PU coating is waterproof but allows air to escape. When compressing, you can easily push the air out without needing to operate an extra vent. The compression straps make it easy to evenly compress soft items.
