Delivering the all-weather reliability normally associated with synthetic insulation and the lightweight, compressible performance of down, the Big Agnes Spike Lake 14 Degree sleeping bag is a high-performance option for cooler weather backpacking.
The Spike Lake 14 Degree bag is insulated with 600 fill DownTek insulation. Down insulation has long been renowned for its compressible properties and efficiency in delivering an excellent warmth-to-weight ratio. The shortcoming of down has been its susceptibility to the effects of moisture, losing much of its performance qualities when wet or damp. DownTek insulation utilizes nano technology and a proprietary application process to provide water-repellency and both anti-microbial and anti-bacterial protection. A nylon rip-stop shell also features a water repellent treatment and provides lightweight durability.
Insotect Flow technology is used in the collar and side panels of the Spike Lake 14 Degree to help eliminate cold spots, regulate the movement of down and offer better body heat distribution. (Traditional baffle construction is used in the main body of the bag). Strategically placed Flow Gate construction eliminates lateral and vertical down shifting by using vertical chambers with "gates" to control the position and density of the down insulation.
A number of other design features bolster the warmth and comfort of the fully-insulated, mummy-shaped Spike Lake 14 Degree bag. An insulated contoured hood with a drawcord and cord lock and a draft tube located along the length of the 70” zipper lock in heat and keep out cold air. Integrated connection loops enable you to use the bag with a liner (sold separately).
Available in Regular (fits to 5’ 10") and Long (6’ 6") lengths, each Big Agnes Spike Lake 14 Degree sleeping bag includes a nylon stuff sack.

- Would not recommend this bag for temps below 35
Likes: Compressibility, tabs for hanging after use.
Dislikes: A little history, 62 yr old, learned to camp & hike as a scout (Eagle), having camped year round, decided to upgrade with some ultra lightweight equipment. Chose This bag and it failed miserably. Had to sleep with all my layers on in 24 degree weather. I could say a lot but I honestly believe the rating has conditions not mentioned. I will have to purchase another bag and pass this off as a 35 degree bag. Money wasn't the issue. I have a Big Agnes tent and pad and they couldn't be any better. Will look elsewhere at other brands to continue my reprise of cold weather backpacking.
