• Yes I have one.
    Why do you need a bleed valve? I have found if you turn the top once on a bag, then use a knee to compress no valve is needed really.

    As atk said. I tend to double bag, or even tripple anything important. My sleeping kit goes into a sea2 summit ultra sil bag, and then inside of dynemma or thicker tri laminate bag. Sleeping/insulation isn't something to try save gramms or a little space when it's so vital.

  • I've got a thicker drybag already so the idea was to do exactly what you say, compress and shove inside another bag.

  • Cool. Personally I wouldn't other with compression one you can get 8/10 of the effect with a knee.
