The Therm-a-Rest Centari Sleeping Bag is a synthetic sleeping bag for winter backpacking. The 3 pound, 15 ounce (regular) bag features an EN Comfort rating down to 23°F. Set up your tent and then slide your air mattress through the SynergyLink™ connectors to keep you from falling off your mattress mid-sleep. Everyone hates that falling feeling in the middle of a dream. The 20D nylon shell has been silicone durable water repellent treated, which allows moisture to bead up and roll right off the surface, instead of soaking into the fabric. Pretty handy when there's condensation inside the tent. Rest easy through the night as you snuggle inside the eraLoft™ stuffed bag, complete with draft tube to block the zipper and a draft collar that says no to cold air at your neck.

Old Goat from
LOW VOLUME LOW WEIGHT FOR A SYNTHETICI find no real short comings in this bag. I will be using this bag in Ohio where temperatures can be very cold but, always damp. I am 5'10" 220Lbs.and 72 years old. I bought the long because it was on sale but, after using it the regular would not have worked for me because I put my clothes in the foot. Slept in it one night as a test in my yard, with a base layer, Trail Pro pad, REI bivey bag and the real out side temperature -1 and this combo but for sure the Centari kept me warm enough that I do not think that -10 would be an issue. Woke at 06:30 my usual hour warm and dry with very little or no condensation.
