User Review: Eureka! Men's Casper 15
Fill: synthetic insulation
Temperature Rating: 15 F.
Weight: Bag is 2 lbs. 15 oz.
Price Paid: $80
I bought this bag for Philmont, trying to stay warm and light. It worked out very well, with the temps. getting into the high 40's. When I returned home to upstate NY, I planned on making this my regular fall bag.
Went on a fall trip to Canada, temps in the high 30's, and the bag was cold on a Big Agnes Clear View pad. Contacted Eureka and they sent me a new bag. Tried again, this time down to low 30's, bag still cold. Eureka replaced the bag with below zero bag.
I would recommend this bag down to around 40 F. It packs small and is light, but is not up to its 15 degree temp. rating. The important lesson here is that Eureka stands behind their products.
