i did not like my 20 deg slick bag at all. i froze my butt in 40 degree weather.
i got the alpinlite..and i cannot wait to give it a go. i'll be using it in the cold ass AZ desert in a few weeks. last year, i couldnt even use my slick bag..i had to go and find my 0 deg, beat up marmot bag. which was too warm..it was awful. too cold, too hot.
talking to people..i just closed my eyes and thru the money at WM.
the zipper is awesome!! no snags yet!! i have a bum shoulder, and i tend to snag every bag i own..first zip with the slick was a disaster..my brother had to rescue me. haha.the zipper design is super smart..and the storage bag is better than any storage bag i have ever seen. dumb to get all excited for a storage sack, but the thing could be my laundry bag..it is burly.
