REI pouch with carrying handles

Does anybody know what this is? Somebody gave me this with their old pack.

    It is almost certainly a bag designed to carry something liquid or perhaps (but unlikely) act as a dry-bag. The thing on the lower right is a valve for pouring - like on a box-wine. Can you supply some photos of the opening and other side?

    Does the top of the bag seal in any way?

  • Can you post a little more info about it? It looks like it might be able to seal and hold water, can it? Maybe a shot inside as well.

    How do I add more photos? It seems this site will only let me add one at a time.

I expect it's a camp tap. You fill it with water, hang it somewhere by the handle, and can get a little water from the wine-box like valve on it. It doesn't take up space when it's empty, unlike a bottle, and you don't need two hands to operate it, are less likely to overpour or spill, etc.

Here's one of the water storage bags REI sells these days:

  • I'm sure you nailed it. The bag is obviously meant to be filled by scooping from a water source--fine if you have clean, deep enough water available but it would be nearly useless with shallow water that could still be recovered fine with a pump. Commented Feb 14, 2021 at 2:04

After you pack clothing into it , it can be evacuated through the valve to compress the clothing to the smallest volume.

    Huh? The top looks open and it's REI--why in the world would they be selling a vacuum-based compression bag anyway? There's rarely a source of suction where REI products are being used. Furthermore, if it is a vacuum compression bag why the handles? That's wasted weight, anathema in the backcountry. (Now, they might sell a roll-up compression bag but it wouldn't look like that.)
