Exactly what I needed at a fair price for the quality.

    Most of the camping I do is early spring through mid fall. This bag has been perfect for taking on far road trips and spending weekends at sites. It compresses great although I would recommend buying a different sack than the one that the bag comes with. The extension zipper is really nice and gives extra wiggle room. The colors are great and the material feels wonderful. The mummy zip is nice for the cooler evenings. I camped mid June and the temperature ranged from 40 degrees and raining to 90 degrees and humid. The bag worked out well. Definitely choose synthetic over down-- It won't bunch up. Mountain Hardwear is a brand I trust for sturdy and long-lasting gear.

    The zipper is driving me crazy!

      Yes, the bag is warm and comfortable and packs down to a descent size, and it has two convenient storage pockets inside and the expandable zipper for when it's not below freezing...I would give it five stars, except I've been sleeping in it for a month and a half and have yet to manage an effective way to zip it up without it snagging. At best, I can get it 90% zipped, but it's that last 10% that is nightmarish. And it's cold, so I want to get it zipped all the way up...but it ALWAYS snags. Always.

      The zipper is driving me crazy!

      How small does this thing compress? I've...

      How small does this thing compress? I've been borrowing my dad's for camping trips and such, but his is to big for my taste, so I'm looking for one of my own compressed as tightly as I can. So how tight is that?

      Hi there, I just receive this sleeping bag...

      Hi there, I just receive this sleeping bag from you and notices that the nylon stuff sack and mesh storage bag are missing. I thought this bag comes with a Nylon stuff sack and mesh storage bag?
