I brought and used this liner on a month-long trip in the Sierra Nevadas. It was warm but I don't think it added 15 degrees to my bag (not that I needed it to, I use a 25 degree bag). For me, this is a comfort item. It's like having cozy sheets inside your sleeping bag. I used to stay comfortable and to keep my bag a little cleaner. For my purposes, it worked great. I think it's a good liner but not necessarily any better than any other liner out there.

After buying, trying, breaking and returning the lightest, the very light and the pretty light "plastic" water filters, I decided to go with quality over weight savings. This is not a lightweight filter. However, it is the BEST filter when you must have clean, safe drinking water. It is a breeze to use and to maintain. I just used mine for a month straight and had NO problems and did not have to clean it once. It's hard to spend so much $$ on a water filter when less expensive options are out there but trust me, this is an investment you WON'T REGRET because it may very well be the last water filter you buy - it's that good.

My husband and I just spent a month in the high backcountry and loved our NeoAir pads. I've tried a lot of different sleeping pads; from fancy/unique shapes, short, long, foam, self-inflating, uninsulated air pads etc. and this is, by far, the most comfortable pad I've ever used. I've heard some questions it's durability but I just slept on mine for 26 straight nights and it did great. If you like to use your pad as a chair, this is not for you. If you just want the best nights sleep in the backcountry, you will love this pad.

My husband and I just finished a 230 mile hike in the high Sierras and we both carried this bag. It was fantastic. Not only did they keep us warm but we could move around freely like I've never done in a "mummy" bag. We absolutely love these bags.
