We all know and love Therm-a-Rest sleeping pads. Now along comes a fart sack, made to pair with the NeoAir sleeping pads. The Antares has a few cool tricks up its sleeves.
The Antares is updated for 2014 and is now comfort rated to 15F, thanks to added box baffling for the 750+ down, which seems like a reasonable rating to us if you're using a decent pad. Our bag weighed 2lb 4oz with included storage bag, a bit more than the official 1lb 15oz list weight but still on the lighter side of average. Fit is Goldilocks, not too small and not too big.
The Antares puts its weight to good use, packing in a collar, draft tube and trapezoidal foot box, as well as a internal stash pocket. The real trick on this pony is the strap system that holds it to a sleeping pad. Two elastic straps let you toss and turn to your heart's delight while keeping the bag static. Using two straps instead of a sleeve means side sleeper don't feel like they're wearing a straight jacket, because the bag can flex with your knees without coming off the pad.
The system works as advertised, which is good because the Antares doesn't have any insulation on the back of the torso area. Overall the Antares is a great bag to pair with a great pad, and guaranteed to keep you from rolling onto a cold tent floor in the wee hours.
