Pyro 0 Degree Down Sleeping Bag
Sierra Designs   Pyro 0 Degree Down Sleeping Bag

The new Pyro utilizes our new Core Comfort Technology, to allow a comfortable and warm night wherever adventure takes you. Core Comfort Technology combines innovation in insulation location and sleeping bag construction. Meaning the down fill is more strategically placed, prioritized according to a comfort body-mapping process. Maximum loft and warmth are ensured by an advanced double-baffle system. The combined technologies provide warmth precisely where needed.

By mapping the body`s warmest and coolest parts, Sierra Designs` Core Comfort Technology places sleeping bag and apparel insulation where it`s needed most- directly over the torso- to maximize heat retention for warmth without bulk. CCT apparel cools through non-insulated areas during high exertion activities and retains heat during times of low exertion while CCT sleeping bags require less insulation to keep users warm overnight.
