Compress your gear down to a third of its capacity with the ULTRA-SIL Compression Sack from Sea to Summit. The ripstop Cordura fabric is ultra-durable, and the four straps provide even compression for a more packable shape and size. The pull handle on the bottom makes it easy for you to grab the sack and go. It's easy to pack things into the slippery finish. The outer is water-resistant, so your stuff will stay protected if it starts to rain.
