Truly the best of both worlds, this bag can go from a 15 degree bag to a 30 degree bag in the blink of the eye. There is a removable Dual Temp down torso panel that allows for a quick change if the temp changes. The panel also makes a great pillow. The Pyro Maniac sleeping bag has all the bells and whistles without sacrificing weight.
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.
