Jack and James may help you feel warm around the campfire, but you'll freeze if you don't end up in the Big Agnes Whiskey Park Sleeping Bag once the bottle's empty. Thermolite Extra insulation keeps this bag warm in freezing temperatures, and it stays warm even if you happen to spill a little liquid on it. Big Agnes treated the shell to shed said liquid too, thereby keeping your sloppy self nice and cozy throughout the night. Inside, the Whiskey Park's cotton polyester lining feels just like your bedsheets at home. The hood un cinches with a few toggles for better comfort in warmer weather, and there's a pillow pocket so your head doesn't lose its much needed softness in the middle of the night. Draft collars cover the dual zips and hood to seal your body from winter's winds. Big Agnes also included internal loops for liners, external loops for airing the bag out, and an integrated sleeve with stretch panels to fit twenty five inch sleeping pads.
