Big Agnes 15°F Crater Down Sleeping Bag with Sleeping Pad - Mummy, 600 Fill Power

My son loves the bag slept in it the night we got it. But I'm still not on board yet. Concerns about warmth rating. It should be ok down to around 30F.

Awesome bag and fits my 5'7" husband like a glove. Any taller though and it would be a very tight fit.

I love this sleep system. With the included Big Agnes Isulated Aircore Pad, its the best system I've used. I am an extremely restless sleeper-side /belly. I have to have my legs and arms at angles that most mummy bags would not allow. I had three good night's sleep with this bag and that's rare for me. The pad does not move and I can roll over and from side to side. I am around 200lbs right now and It works great for me-it insulates well and I was WARM down to the 30's. It rained hard one night, with frost in the a.m., and I was toasty. I was worried about the lack of insulation on the bottom but the pad and my thermals made things work out just fine! It is also light! The pad and the down bag pack down small-both fit in the sleeping bag compartment of my pack. I am a lightwieght packer(not UL) so this system is the perfect balance of comfort and weight for me. The only thing I didnt like was the feel of the pillow sleeve. I stuffed a jacket in there for loft and used a pillow over that.

I used this sleeping bag on a backpacking trip in early spring. The temp was approx. 30°F and it was a little on the warm side in the bag. This is a great purchase and will work well for backpacking. The pad inside the bag is exceptional never roll off the edge of your pad again.

This is a very comfortable bag and overall happy with its performace. Zipper is a little pesky at times but seems durable. Also does not come with compression sack but hope it will compress to a good size. The long is perfect fit for me with room to move(5'11-177lbs)
