- Familiarity: I've used it once or twice and have initial impressions
Combine the bag with a Neo Air pad and the performance/comfort is hard to b beat. Used a couple times with morning temps in the 30s....no cold spots and I sleep on my side etc.
Does the down have any water treatment?
Does the down have any water treatment?
Nope just your average high quality down you would see from any of the major manufactures using 700 fill or better. The shell is DWR coated though which helps with condensation in the morning.

- Familiarity: I've put it through the wringer
This bag solved alot of problems that other bags have concerning comfort, whether you have been too hot or too cold this bag is designed to work with a sleeping pad to regulate the temps in the bag so that you sleep soundly through the night. The design is unique and very cool, the down in the back from about the small of your back to the middle of the shoulders is eliminated so that your body heat can permeate into the pad, which mixes with the cold air from the ground. The end result means that your bag warms up faster and doesnt feel too stuffy once it does, and the comfort lasts all night. I slept sounder, longer and fell asleep much faster compared to other bags I have used in the past. Another cool design feature called Synergy Link Connectors which are strips of an elastic material that hold your sleeping pad to the bag itself, which means you can move around and find your preferred sleeping position without falling off of your pad. All around I would highly recommend this sleeping bag, especially when used with a Therm-A-Rest sleeping pad such as the Prolite plus. If you are looking to fall asleep more soundly and wake up rested and refreshed ready for whatever the day has in store pick up the Antares!
This picture doesn't quite do it justice. This packs down SMALL, as well as light. I fit this bag, my BA Q-Core, the Thermarest NeoAir pillow, and my rab generator, and a rain jacket all in the bottom compartment of my Deuter Aircontact pack (with room to spare). Great backpacking setup!
Tough to admit
This is a great bag. I am a BA guy through and through but I decided to pick one of these up because the link system intrigued me. I love the BA system but it has it's down sides. The full sleeve restricts any knee lifting or sitting up. The Synergy Link Connectors that Therm-a-Rest uses allows for a more unrestricted feel. I prefer this system over BA. The bag is well made and has nice features. I have used it down to the mid 30's and I was toasty. I actually removed my socks. There isn't a whole lot of room for a pillow in the hood, this is the opposite of BA, they have a built in pillowcase in there system bags. I like both ways I generally wear a hat and do not use the hood so it is basically the same.
I see what ya did there...
And man i love it, hands down the best bag i have owned to date, love the combo between this and my therm-a-rest Neo Air sleeping pad, perfect combo to save weight and stay just as toasty warm. The only draw back i could possibly have is that it isnt a crazy spacious bag, but dont get me wrong it isnt to tight either. Being a side sleeper it is sometimes hard to get it all perfect but this certainly is the best i have found. zipper stays in place all the time with no snagging and the bag even has a handy pocket on the side to put essentials. All in all this is a great bag if your looking for something that is light weight and combos up with a sleeping pad (bag does not have insulation on back panel)
Applause to Therm-a-Rest!
This bag is a great 3 season bag. When paired with the Neo Air pad I honestly don't think there is a better combo of comfort and weight on the market right now. I love this bag!
Therm-a-Rest did their homework
This bag is simply incredible. It makes me very happy that Therm-a-Rest did their homework and didn't rush a release of this product. So far I've put about 9 nights in this bag, so I cannot speak to it's long term durability. However, my first impressions are as follows:
Ergonomic design - I'm 6'4 and 210 pounds, slept like a baby
Wider at the knees and shoulders, making side sleeping and tossing & turning comfortable
Elastic on the bottom attaches to most sizes of pads. I didn't use them for half those nights and it was fine.
The hood holds pillows in better than other bags
Bag appears to be well made. Multiple layers of stitching
Zipper DOESN'T snag! (My favorite)
I was very warm at 30 degrees & it breaths well when it's warmer
Compresses to practically fit into my pocket (figuratively speaking)
Price (although it's still worth it)
Don't know how it will last in the long run
If you don't use the elastic bands, and the bag turns over with you, you'll get cold fast
There is no insulation on the bottom, making a pad essential (not really a con though, again, Therm-a-Rest did their research!)
My fiance has the Altair 0 Degree, which has insulation on the bottom, and she loves it. She gets cold in the damn hot tub, so you know that bag is top notch!
Most Comfortable Sleeping bag
I was a little skeptically when Thermarest came out with sleeping bags. I have loved their pads for many years, but was unsure the bags. After getting in one I fell in love with it instantly. This sleep system allows you to attach a pad that is either 20" or 25" wide. I like this because I can use my backpacking pad when I am backpacking and my car camping pad on car camping trips. The foot box and hood can move independent of the pad. This is huge plus for me because tend toss and turn. So when I am moving around in the bag the pad is not moving the bag is. I can even curl up in the fetal position and bag will move with my body. The weight is great at under 2lbs. I have slept in a lot of bags over the years from, Marmot, North Face, Kelty , etc. and I have to say that this is by far the most comfortable bag that I have ever been in.
