Buddy brought this on a climbing trip this spring, best water filter I've ever used.

Just fill the bag up, connect the filter, and presto quick easy filtered water.
So quick and simple there's no need to hang it up, you can easy refill water bottles in a couple minutes, then it packs down super light.

Extra plus: use it to fill up your water bottles, refill the bag, and then carry unfiltered water in the bag until your bottles are empty, then use that water to refill again. Can't do that with a normal filter.

Wow, so I got a couple of these to rack nuts on, and boy am I impressed. They weigh next to nothing, and the non-snag nose keeps life hassle-free. They are so nice, I find myself showing them off to friends, grab one, you'll be impressed.

Own it, use it, like it.
Favorite feature? The hassle-free non-adjustable legs loops, lets face it I never find myself in a situation where I've put so many layers on my legs I can't fit the loops around them.

Amazing jacket!
I've owned it for one year now and it has taken care of me everywhere from Yosemite belay sessions to cold desert nights to unheated college housing.
The wear and tear this thing has taken is considerable and yet it shows practically NO damage. I've slept directly on the ground and even chimneyed up a climb in Joshua Tree (sharp granite!) and never had a rip.
Most of my other gear comes from different companies and was a bit hesitant to go with TNF, but the quality I got for such a low price is amazing. My only gripe is the hood, pretty useless unless its raining and then why would I be wearing down anyways?
