This bag is like sleeping in a cloud. It is semirectangular to give people like me who hate mummy bags a little extra room. It is extremely lightweight and packs down so small. The 850 fill down is ultralight and ultraefficient.

I have used it so far down to probably somewhere in the 30s and I have been more than plenty warm. That is wearing just boxers and a tshirt. The bottom unsips to allow some airflow and the bag can unzip entirely and zip to another bag if you were sleeping with a companion.

I got mine in the 6'5" version since I am 6' tall and wanted a little extra room to keep stuff at my feet.

I love it, I love it, I love it. Western Mountaineering is great stuff.
