Just ordered the SD Cal 30 from backcountry.com because it was 20% off and… well because I think it means I can have my cake and eat it too. 800 fill down? check. Under 1.5 lbs? Check. Not having the old PNW "Down Anxiety" with a little tarp? Check.
Search turned up nothing, although google gave me a good youtube video from Prolite Gear. Stated weight is 23oz in a long size, and that is with a 64" shoulder width. Sounds competitive. Anyone else have any experience with it?
I'm planning on the AT starting in May, and with a poncho tarp the Dri-Down thing has my attention.
