Big Agnes Mystic SL Sleeping Bag: 15 Degree Down - 2008 BCS

I have been very happy with the performance of this bag. I bought my wife the Lost Ranger which is a roomy bag and I found this on sale so I purchased it. I feel it does restrict my movements because of the squared mummy style. It is a little snug if I sleep on my side. I am a fan of down bags and this one packs down small, is lightweight and comes with both a storage sack and a stuff sack. As with all Big Agnes bags, it does not have any insulation on the bottom and relies on your sleeping pad for that. You will want the 20 inch mummy style pad for this bag. I prefer the Big Agnes Dual Core pad.

This is a great bag and good quality. I am 6' 170 so I got the long and it was a good choice. if I were to do it over again I would maybe get the mummy version because I am skinny and I have a ton of room in my feet and legs so it takes 30 min. or so to warm it up but once I do it is great. I love the fact that I stay on my pad but it is a little okward to sleep on my side but it works. One thing to know is that it is a big set up so if your backpacking tent is small you may want to consider something else. for example if your tent is 30 sq feet or less and you are sleeping two people in the tent you may not be able to fit two of these. I really like it and would buy it again.

I got this to upgrade from my BA Encampment, the weight savings alone was well worth it. It feels warmer and softer compared to my old synthetic. I only wish BA would put a 25" pad option on all their bags.

My one complaint with the Lost Ranger was that it was a little heavy and should have used a higher quality down. Well this is the answer. This is the perfect bag for me. I am a little claustrophobic and the smaller mummy bags constrict me too much. This one combined with the way the pad slides into it allows me to toss and turn without a problem. It is a great bag.

As always, BA makes great, innovative products. My only quibble is with the temp rating, but to be fair, I usually have that with temp ratings. I'd put this 15 degree bag at more like 30, but that's just my opinion. I still wouldn't trade it for the world - super light and well designed.

Absolutely LOVE my Mystic!! ... both my husband and I own and enjoy this 'as-comfortable-as-our-own-bed' Big Agnes bag/pad/pillow!!! (We had read one should, for camping, try create, as close as possible, one's own bed at home!! The Big Agnes system has accomplished this for us!!) Our last backpacking trip was a bit 'rainy' and cool, but we were very snug!!! Thanks Big A !!! : )

I have a couple of other Big Agnes UL/SL products that I love and this bag is no exception. First night out with it at close to the 8k level got pounded by heavy winds and wet snow but was toasty through the night. Being able to slip my existing rectangular pad into the sleeve was great. Because of the heavy winds and precip some moisture did drip onto the bag but nothing seemed to penetrate. I'm a bit of a thrasher at night but this bag has plenty of leg room so it was not a prob.
