Needs a gusset at zipper line. Cold air coming thru zipper line.

Great sleeping bag

I got the long size, and like how it gives me some freedom to move around/stretch out more than other mummy bags I had. Super warm, and packs down to a small size. I really like the straps on bottom to put around my therm-a-rest pad to keep it from sliding around. Zipper is durable. Happy with the bag overall....if Im super picky Id want a more neutral colour.

Super warm bag

I was skeptical as to whether or not this sleeping was going to get the job done as I am a very cold sleeper, but it it amazing. First time in a LONG time that I have not had to sleep in all of my clothes, a puffer coat, and beanie! Very comfortable, and I stayed so warm on the AT I was so glad I pulled the trigger on this bag! I highly recommend it. I have an ultralight thermarest sleeping pad and had no trouble fitting it inside the straps on the back of the sleeping bag but the standard size might not fit as many have stated. I have not tried it with a standard bag. Packs down tight and is small and light to carry. Will be taking this gem to Yosemite in June and I'm so glad to have it.

Warm, comfortable and surprisingly compressible

Fantastically warm and comfortable bag. I would give 5 stars, but as someone else commented, the straps don’t fit my thermarest Xtherm pad, which seems like a silly oversight. It wouldn’t take much to make the straps an inch or two longer. That said, overall I find this to be one of the warmest, softest and most comfortable 0 deg bags I’ve used. The foot box is luxurious. And it all compresses down to an impressive small size. Well done.

Excellent Design That Performs!

I took it out in 7 degree temperatures with industry certified thermometers and tested it out! I would not recommend Thermarest Parsec 0° Down Sleeping Bag below 5 degrees after my usage and testing. It might work at 0 degrees, but I can confirm a good night in 5 degrees. Which is great, given most bags never are comfy near their actual bag rating. With space to add a small insulation layer to extend the bag rating a little! The Therm-A-Rest Parsec 0° Down Sleeping Bag is comfy, well thought out and has even warmth! Here are the results! Air Temp: 7° Degrees Starting Temp In Bag: 32.1° Degrees 5 Minute Bag Temp: 55.4° Degrees 10 Minute Bag Temp: 65.4° Degrees 15 Minute Bag Temp: 72.6° Degrees 20 Minute Bag Temp: 76.6° Degrees 25 Minute Bag Temp: 78.8° Degrees 30 Min Bag Temp: 80° Degrees 35 Min Bag Temp: 80.9° Degrees 40 Min Bag Temp: 81.6° Degrees 45 Min Bag Temp: 82° Degrees

Warm feet

I've used this sleeping bag once so far and love how warm it kept me. Temperatures were down to 34 degrees fahrenheit but was comfortable. I didn't need a liner or even socks.

The bag keeps me warm

The bag keeps me warm in winter conditions and is comfortable but on my first trip using it the zipper got stuck on the fabric and ripped a hole in it, even though it has a fabric strip to prevent this scenario.

Great Sleeping bag, exceeded expectations in really harsh conditions

Winter camping in the Pacific Northwest is serious and dangerous if not well prepare, this sleeping bag worked better than expected pair with NeoAir XTherm R value 6.1, the temperature was19 degrees and I was literally hot to the point that I had to open the upper part of the bag to cool down, this is a zero degree sleeping bag so I know it will deliver if im at lower temperatures just fine. 5 stars hands down.

High winds, with snow and rain.

This sleeping bag is great! I looked forward to crawling into this bag after a cold long day of hunting! Light and warm and amazing!
