"This is a fine sleeping bag, although a bit pricy. Part of the reason I selected this back was due to the fact that it is manufactured in the USA, could be customized (girth, length, material, fill), and had 750 down and a good recommendation. The bag is well made and has kept me warm in the Colorado Mountains in June at 11000 feet. The zipper operates smoothly. Not much more I could ask for.
Customer Service disappointed me. before my purchase I called to disuss features of their bags. Since I don't live in Seattle and I couldn't visit their brick-and-mortar store, I decided (upon advice of the Customer Service rep) to order 2 bags, try out the fit, and return the one that didn't fit as well. I did this and shipped back the bag that I didn't like (not the hummingbird). A few days later I got a call from a different Customer Service rep claiming that the bag came back too dirty to sell as new and that they would require a $50 cleaning fee. The bag was tested at my house, not outside... ever.
This was very frustrating since THEIR customer service rep recommended the order-2-return-one idea. Due to this I've ended up paying nearly $400 (including the return shipping) for a bag that, had I gone to REI, EMS, etc and tried out a TNF, MARMOT, etc. I could have spent $250 and gotten comparable quality and performance."
