anyone have any experience with event dry sacks ... im wondering if clothing would dry out with them ... possibly with a hot nalgene inside to push the moisture out?

thanks,

Eric,
I use one for my sleeping bag and down clothes. It rides in the bottom of my pack pretty well compressed and surrounded on three sides by the pack fabric. In cold weather the top of my sleeping bag gets damp/wet from breathing on it. It is still that way went I unpack at night.

YMMV

I have a Sea to summit pack liner and sleeping bag compression sack which have event bottoms, with a heat source it might work.

A hot water bottle seems like it would work to some degree. It would work best if the entire garment or item was wet. If only a portion of it was wet (like the cuff of a jacket that got wet in a stream), then the heat source will probably dissipate some of the moisture from that one area, but might also spread the steamy goodness around to all other contents of the sac, dragging everything down to the next level of winter wetness hell. Or it might work beautifully. Try it out and let us know!

i was hoping not to spend the moola and be a guinea pig ... lol

It seems like you'd need to put the bottle at the roll top end to make the water go towards the eVent.. If you put the bottle in the 'middle' then it would push half the water towards the roll top instead of towards the eVent.

If this hypothesis is correct, putting the bottle at the end would possible cause it to cool faster than the water can be pushed out. Or maybe, the heat wouldn't be great enough to push the water all the way to and through the eVent.

It would probably work though. Just put the bottle in the middle, and during the day repack it to reposition more wetness towards the eVent.

Totally an uneducated hypothesis...

Eric let us know how it works! ;)
