I must second the recomendation for the Feathered Freinds bags. They are very well made and are available in an assortment of sizes.

They are also made in Seattle.

I have a WM Caribu (35*), FF Swift (20*),and a Marmot Hydrogen (30*). These are summer, fall/winter and inbetween bags respectivly. I definitely think the FF bag is the beter of the three, and it was more expensive.

Since I haven't used the Hydrogen since I got the FF Swift I may sell the Hydrogen now.

Good luck with your choice.
