User Review: Cabela's Boundary Waters 40 (Long)
Fill: 650 fill down
Temperature Rating: 40 deg F
Weight: 3 and a smidgen
Price Paid: $130 US
This is a great bag for a big guy like me (6'3", 235lbs) who sleeps hot. Stuffs down to canteloupe-size, and opens out to a 70" circumference that gives me the shoulder room I need (I wear a 50 coat size). Although it's rated to 40F, I have used it down to 20F and was still comfy with long johns and a stocking cap and I still had the foot vent open and my head out. I'd go colder with it, no problem.
Oh - it has a baffled vent in the foot of the bag to help with temperature regulation (I love this feature!), and a small zip pocket at the chest, neck baffle, and drawstring closure for the hood. You can zip yourself up in this one and wait for spring.
Truly waterproof stuffsack included, and light cotton bag for storage.
