The eVent Sil DrySack by Granite Gear. eVent Sil Drysacks are ultralight waterproof roll closure bulk reducing sacks that are ideally shaped for easy and efficient packing. The extremely waterproof breathable eVent bottom allows air to escape as the sack is roll compressed, yet maintains its wonderful block shape that is ideal for stacking in your pack. We also added an arched rolling stay that helps keep the top of the sack open while loading and shapes an easy to grab handle when sealed. The ultimate cure for compression. Reduce weight and bulk!.
This sack is awesome as the eVent fabric allows you to press the air trapped into the out the bottom. I own 2 10L one for my bag and the other for my clothes.Just roll the top over a couple times and whatever inside is good to go even in a downpour. .
This is probably the greatest stuff sack I own. Roll it three times and its water proof, it also allows you to push tons of air out of it and packs down really well. I have the 25 liter bag but really want to get a couple more.
I have two of these bags, the 13 L and the 25 L. The 25 L will hold my down bag, tent, rainfly, and footprint and I still have room inside. The 13 L is perfect for my sleep pad. Both bags are super water resistant and seem very durable.
"I really enjoy this dry sack, it allows you to press air out of the pag to get a tight fit."
What I really love about this dry sack is the eVent fabric which allows one to press the air trapped into the out the bottom. I find the product great for storing packable clothes in that can be pressed down very firm due to he eVent fabric.
