Imagine hitting Pacific Crest Trail with only one sleeping bag in your pack. The Therm-a-Rest Saros Sleeping Bag can offer long-haul trekkers blissful sleep from late spring through early fall. Synthetic insulation resists moderate-cold temperatures, and an external water-resistant coating helps the shell repel light moisture. This is a rugged and reliable workhorse of a sleeping bag that's just as comfortable as it is versatile.

Review
Perhaps it will be useful. After every day using this bag during 1 year it is not comfortable even at 10 C degrees. During first 7 months it was ok, but later it’s pressed and started absolutely not warm.

Wonderful sleeps
I am a side sleeper and am able to do this in this bag which I am extremely happy about. The foot pocket is a very useful feature and the no catch zipper with baffle is impressive. I am very excited about my new sleeping bag.

Need wider SynergyLink connectors but other than that it’s amazing
Paired it with the Trail pro sleeping Pad Regular Wide. Sleeping bag has SynergyLink connectors but had a very hard time connecting it. Wish there was a wider SynergyLink connectors. It almost felt like it would rip from the sleeping bag so I ended up removing it. Other than that it’s amazing, kept warm in below 20 weather. Very happy with my purchase. Highly recommend it

Saros 0° Sleeping bag
I think it is so pretty. I love the the colour scheme. I finally got a chance to use it this past weekend in the mountains. It was a bit confusing experience. The temp at night was probably 45°. I wore a sweater and down vest to bed ( I always do while camping). I wore long johns and 100% wool socks and at first I was toasty but then about 15 mins later my legs got really cold and my feet were freezing. I was really worried because I had no other option but to suck it up. I was freezing. I could feel air from all sides from my legs down. After about 2 or 3 hours I finally decided to put my pants on too ( just standard polyester hiking pants) and I put my jacket at the bottom of my feet and once again felt toasty and could rest for the night. I have no intentions of replacing this bag. It was expensive for me and I love the colour scheme. I plan on buying a liner and a light down mummy bag that i can use as a blanket and hopefully that will solve my problem. But I was not expecting that situation as it is supposed to be a 0° bag.

Perfect Bag for Damp Weather
Great bag for cooler weather when the air is wet or it's raining. Dries quick and stays warm!

Roomy and warm in all the right places
I currently use this bag for winter camping in the desert. The comfort for me is the top sell. The price was also very workable for me. I think the trade off for the prices is the large pack size that comes with the synthetic fill. Despite the size I'm happy to have made this purchase as i know I can rely on it for the comfort and warmth. Eventually I'll replace this bag for myself with something that does compress more and pass this off to my clients which I'll be able to do with full confidence.

Solid Synthetic Bag with Features
First-things-first, I'm allergic to down, so Thermarest's down bags simply aren't an option for me. They look rad, but I can't use them. I grabbed the Saros for my 20-degree do-it-all bag, and so far I've been really satisfied. It's been through a year of use, and so far the fill hasn't packed down, the zippers are still functioning great, and I can pair it with my Proton blanket for those very cold nights. Also, didn't realize it came with the foot pocket, but that thing is rad! If I had to pick one thing I don't care for, it'd be the connectors that wrap around my sleeping pad. They just don't quite fit my pad. I'm 6' tall, and the Regular size just fits me.

Great sleeping bag
This is by far the best sleeping bag I've ever slept in. So warm and comfortable. I would recommend buying a sleeping pad to use under the sleeping bag. It's nice that the pad is kept in place with straps so you don't roll off when turning in your sleeping bag.
