Review on Sea to Summit Ultra-SIL Compression Dry Sack, Lightweight Waterproof Bag by Benjamin Robinson

Great upgrade to an already great bag. This bag is extremely waterproof. Compression + ventilation make it ideal for tight packing. You can actually pull the straps to make the contents smaller. It's good for clothes, sleeping bags, groceries, tents and other items that need to be protected/organized. This Ultra-Sil case is slightly less durable than the original. eVent compression, but I like this version better. The small 10 liter version (images below) is suitable for a very small sleeping bag/blanket, down jacket or change of clothes.
