Question: Has anyone slept in this bag at its rated temperature of 20deg F?  How did it perform?  Thanks.
Document: I used it for outdoor camping at 4500 feet in Arizona in December. Just the right sleeping bag for me.
I am 6'2&#34; and this bag has plenty of room for me. Zipper works great and the overall construction seems very sturdy
This sleeping bag is great. I am 6ft., 2in. and I fit in this bag very well. I would recommend this bag.
Came quick and it's an amazing sleeping bag, took it up to Big Sur and even on a frigid night, I was more than warm and comfortable.
Great bag without the big name price. Fits nicely in a pack also. lf you are over 6' 2 it might be to short in the 80&#34; lenght.'
one of the best sleeping bags ive owned and used. kept me very warm in 45 degree weather (havent tested colder)this is not one of those bags you have to have professionally folded to go back in the stuff sack. you can literally just stuff it back into the stuff sack it came with. great bag at a great price
Ended up using a compression sack from walmart....it compressed a bit but didnt really give much more room in the backpack. I bought this sleeping bag mainly for the wider width in the shoulder area as my husband is pretty wide there. He would have probably popped the zipper on the Evader as its only 32&#34;. The ALPS bag is much wider.
We did two days, lows in the 30s. Probably could have strapped it to the bottom of the pack but we had the self inflating ALPS sleeping pads strapped there. All in all it is a good warm bag, it is comfortably wide for someone that needs the room, but unless you have a pretty large capacity backpack and plan on only doing an overnight...it wont fit with all the other supplies needed on a 2+ day hike.
Not quite what I expected. I ordered because this was under the &#34;compression&#34; sleeping bag section. But was larger then I expected when in it's sack. Packing list reads that it comes with a compression sack but it did not. It was a standard stuff sack. So I will have to purchase the compression sack seperately.That being said, my son used it at a camping (not backpacking yet) trip & it was comfortable & warm.
Its a warm bag. However, it does not compress as small as my Cabelas Evader 30+ bag. With the Cabelas bag compressed I can fit it into the sleeping bag compartment in my Teton Sports Scout 3400 backpack. The ALPS bag is definitely warmer...no doubt. It just takes up a big portion of your backpack. I did try a compression sack. ALPS Mountaineering medium.
