Integral Designs North Twin
Integral Designs is no longer in business, and the North Twin has been discontinued. If you're looking for something new, check out the best 3-season synthetic sleeping bags for 2024.
This was my second ID bag and I got it for an April trip into the Ak range and for local climbing nights in the 0F range. Same superb foot section, zip and hood but the hood closure is an updated version and works much better than my Renaissance. Also, the extra synthetic insulation in the chest collar allows the stiff synth insulation to seal up tight. This bag too has a custom zipper to match my bivy sack and to decrease weight.
While I like this bag a lot and would buy it again, it doesnt see much local use relinquishing its duty to the more usable Renaissance. I have used this bag to -25F with extra clothing, I was warm but not overly hot during the nights.
