Short story. I bought this last winter for sleeping in an unheated home in the NorCal coast redwoods that ran 43-48 degrees with high humidity for months and I until then this was the best warm weather bag I've owned and used.

I sleep cold, as I'm 66 years old, and this bag was warm from two minutes after I'd slide in all through the night and it was very cozy, just like a bed. I highly recommend the design.

Because I slept on a mattress I hadn't noticed, but on close inspection I found that five baffles on the bottom had NO FILL; that's right, NONE. An email to SD warranty was quickly answered and I was given an RMA to send it in for repair/ replacement.

Several days later I was advised that the bag couldn't be repaired or replaced with the same model. They'd wholesaled all the rest to retailers, so it was suggested it be replaced with the current model. I told the cs rep that I wasn't impressed with the specs. of SD's new Zissou, as they'd gone from 14.3 ounces of 700 fill to 12.7 ounces of 600 fill and he suggested the Backcountry Bed 700/35, as a move up without cost to me, so I said I'd give it a try.

As soon as I got it I knew it would not work for me. The blanket is sewn in at waist level so I needed to slide in my legs and squiggle down and it's the opposite for getting out; not workable for me, as I'm up and down several times during a night's sleep; so an email and back it went.

Now, it gets good. The rep gave me full credit for the retail price of the BC Bed 700 and with an $87+tax charge I bought a real winner and the best three-season bag I've ever had; the Nitro 800/20. It's the shizzz!
