Yes, it's light as a feather. However, the bag has not much leg room (and the half-length zipper doesn't help either) for those who toss and turn during sleep(at least not for me: 5'9", 165lbs). This is a bag for the mummy-sleepers. Get the bag if weight's your primary concern.

A super summer bag. I use it above 40degrees and it does the job but I wouldn''t care to test it any lower than that. It is well made, just 17 oz (on my scales) and fullfills what i bought it for. Lightweight backpacking in temps above 40 degrees. One night it dipped to 44 degrees and I had to put on extra clothing to stay warm so for me, the real temperature rating would be 45 minimum.

western mountaineering doesn''t make low quality products imho.

for what it is, this is a great bag...i mean, it is super light and it rolls up into the size of a football...it's rated at 40 degrees, but i was a bit chilly at 41 degrees with a silk liner...material doesn't seem like it can handle any abuse, but you have to expect that for what you're getting - a one pound sleeping bag...

like i say, it's great for what it is and i'm happy with it...if you're looking for ultra-light, you found it...i sincerely doubt anyone's going to come out with a bag that's going to weight much less....but this is definitely "specialized" stuff...don't expect to have a bag you can use and abuse and toss around and utilize in every situation...

i don't like that it doesn't zip down all the way - only because i usually like to unzip my bags into a blanket...mummy bags are a bit claustrophobic to me...but, they went with the shorter zipper to save on weight...once again, if you want a one pound bag, you're gonna have to give up some options...

and it is pricey, but in my mind it's worth it to cut out a bunch of weight...

not a bag for the casual backpacker...definitely for folks who are looking for ultralight and are prepared for a few disadvantages and are prepared to treat their stuff with care...

It's tiny bag with light weight, great fine denier fabrics for reducing its total weight, It weighs only 1 lbs., very fantastic bag, I have used it for 1 year, everything is alright, but currently I bought a similar down bag from Germany, this bag (model name is pound of "Yeti-Exner Design") it also claimed 1 lbs. for its total weight but with more functions the Highlite it doesn't have, such as draft tube, they have baffle instead stitching thru, as well as long zipper for easy in and out of bag. I like this bag very much!

Of course, the Highlite is also my favor, but less features than Yeti-Exner, This is a little bit bad. Anyway, I still like this bag as simple and convenient..

Not yet, their workmanship is good, it seems having long life for abuse.

This bag rules! It really does weigh only a pound, stuffs into a tiny little sack and is actually warm.

I got the HighLite with the intention of carrying it on long routes in case of a forced bivy. Also for quick, light forrays into the Sierra, it seemed perfect. I can take a bivy sack and my HighLite and just find a nice little flat spot to sleep on. It delivers on both counts!

This isn't magic, though. Western Mountaineering does have some amazingly light fabric and the best down available. But there are definitely limits to this bag. On nights in the low 30's, I have to wear my clothing inside the bag to stay warm enough. (No big deal.) And the fabric does look somewhat fragile. This is the tradeoff for ultralight gear. The zipper only goes half-way down, so you can't vent your feet. But for my purposes, this bag is everything I need and nothing I don't.

Awesome bag, long version only weighs 17 oz and stuffs into nothing. Keeps me warm down to 30 so I can use in all but the middle of winter.
