I looked at the a few weeks ago. SG doesn't appear to be waterproof.I haven’t personally tried it but it looks like this Stone Glacier sleeve is worth a shot
Hydro Sleeve
The Stone Glacier Hydro Sleeve is the perfect solution for carrying water bladders inside your Stone Glacier pack. It is large enough for any 3-liter bladder.www.stoneglacier.com
It looks like it has webbing attached so with some webbing hardware you can probably get it mounted up fine. Let us know what you end up doing!
Paranoia of it breaking or leaking and catching that water in the sleeve. Versus soaking all my gear.I don’t understand why a bladder carrier needs to be waterproof. Reasoning?
Some of the reviews mention it keeping gear dry from a leaky bladder. Might be worth a shot, and you could try seam sealing it.I looked at the a few weeks ago. SG doesn't appear to be waterproof.
I slide my Camelbak into a 1 gal ziplock then slide the whole thing into my pack pocket. And the only reason I do that is because of the one time that it leaked in the 18 years I've been using it. One of the o-rings wore out I guess. Camelbak sent me new ones for all the way around and it's been good since.Paranoia of it breaking or leaking and catching that water in the sleeve.
