great bag

  • Gender:Male
  • Familiarity:I've used it several times

i use these to compartmentalize my pack. They keep everything dry and you can use as a pillow too. much lighter than comparables for the price which is important to me.


Ultralight and strong

  • Gender:Male
  • Familiarity:I've put it through the wringer

As light as advertised. Primarily used inside my 55 liter backpack to keep sleeping bag and clothes dry. 35 liter size works well inside the 55liter pack - taking up about 2/3 of the available space when fully loaded. So far it appears to be durable though that may largely be due to e fact that it's inside my pack 90% of the time. The clear window is a very nice feature.

Is this considered a "Small Size"?

There are 7 options available, ranging from 1L to 35L, so yes the 1L is small. The 35L, on the other hand is quite large.


Well Made

    A well made stuff sack for anything you can imagine, and it has a window to keep track of what is inside. Looking forward to testing its durability.


    I have one similar

      I have a version of this one with an Air Purge valve in it. It you want sturdy and dry with the ability to see inside, this is the way to go! These bags are VERY Durable, and can deal with a lot. The only reason why it gets 4 instead of 5 stars, because its rubbery, it doesn't slide in and out of a backpack very well. Other than that, I have been living out of mine for 4 months, and use it everyday!
