User Review: Slumberjack Super Guide +30°F

I purchased this bag based on the weight and packed size with some reservations on the temperature rating due to the lack of loft. I should have listened to my instincts. A recent 4-day canoe trip to North Florida offered the perfect test when a cold front provided nighttime temperatures of 29, mid 20s, 36, and 46F. In a fully closed tent on a Therm-a-rest pad combinations of a Thermax base layer with lycra winter tights, fleece, hat, and Smartwool socks did not help on the coldest nights. There is simply not enough fill on the top to eliminate cold spots. The final night in the mid 40s was quite comfortable. Treat this as a +40 or 45F bag and you will love it because you simply can't beat the size and weight at this price.

Reportedly Slumberjack is adding 3 oz of fill for 2007.
