Sea to Summit eVAC dry sack

They are fantastic!!

+1

They work great. Very durable and quite waterproof. I've gone days without seeing clear skies and my sleeping bag has always stayed dry.

I consider myself an expert on very few things, but this product is one of them.

Take a look at my profile picture. See the bundle on the back of the bike? I lived out of a large e-Vent sack for 30 days straight. it held a hammock tent, a sleeping bag, and all my clothing.

Nothing ever got wet. Not once. No moisture buildup. The e-Vent bottom even allowed some things to dry inside the bag, which means a slightly damp sleeping bag like a down bag won't sit there and stew all day if it's on the outside of your pack.

It's very durable- I still use it. It's probably seen 60+ nights of use.

This is my second year using one for my down bag/underquilt, and another for my camp clothes. Absolutely love them! I was skeptical in the beginning because I'm a show me kinda guy, but I'm sold.

I have used both and the Sea to Summit Evac dry sack is much more durable than the Sea to Summit Ultra Sil dry sack. Both are plenty waterproof.

I've found the e-vac dry-sack to be totally waterproof and durable so far, but I haven't abused them. The ultra-sil ones do "wet out" after prolonged exposure and pressure. The one thing I don't like is that they blow back-up after compression if your pack is not packed very tightly.

I have the version with the event bottom. It's awesome and works as advertised. Having said that, I have moved away from stuff sacks in general and prefer the concept of a pack liner and allowing my sleeping bag and clothing to fill in the gaps in my pack.
