Sierra Designs Van Winkle

The bag is absolutely wonderful. It's the most comfortable bag I have ever slept in. The stretch design allows me (a sleeper that sleeps in a variety of positions during the night) lots of room to move around. However, one thing that I noticed is that the down is able to escape out of the seams of the bag. I don't know whether or not it's natural or if there is a breaking in period. Overall, the bag is the best I have ever owned (is there a e-mail for the company?).
