1 April 2002
Excerpt: 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.
