Down that's afraid of water.

The Big Agnes Women's Roxy Ann 15 Sleeping Bag mixes lightweight loft with weather protective capability for camping or backpacking in nasty conditions. DownTek treats the lofty down insulation with water-resistant protection to retain its loft and warmth in rainy weather and moisture-riddled environments. Insotect Flow Construction optimizes insulation by strategically placing vertical chambers with Flow Gates to minimize shifting and to ensure warmth where you need it most.

For a roomy, rectangular-shaped bag, the Roxy Ann is surprisingly light and compressible for backpacking trips. Big Agnes also equipped this bag with a draft tube around the hood and a full-length zipper to keep brisk air at bay. Internal loops let you attach separate liners for extra comfort, and there are pockets for pillows and car keys. Since Big Agnes doesn't insulate the bottom of bags, be sure to pair this sleeping bag with a 20in sleeping pad.

Super cute, super comfy.

  • Gender:Female
  • Familiarity:I've used it several times

I really like this bag. I purchased it actually on accident and am glad I did. It is my first down bag. Coincidentally the petit size was on sale, and I just fit the height recommendation for the bag, so I went with it. I'm just over 5'6 and make it work comfortably, but I'd recommend going for the regular size for anyone also on the cusp.

I sleep very comfortably in this bag down to 40 degrees, and haven't yet tried it any colder. I pair it with the Big Agnes Insulated Air Core Sleeping Pad (20x66x3.25) and all fits perfect. I also prefer to sleep with a sleep sack (the neon green one seen in this pic supposedly bug repellent) In the summer time in the desert I actually just laid the bag on top of my Therm-a-Rest Z-Lite pad and slept okay. You definitely want some sort of padding beneath you. I feel spoiled while camping sleeping on the Air Core pad.

I enjoy the extra padding that tucks up around my neck and face, and the pillow pouch where you can tuck in your pillow, so it also doesn't slide around as you sleep. You can't beat this lightweight little bag for the price and comfort!

Super cute, super comfy.

Not that warm

  • Familiarity:I've used it several times

To be totally fair, I did buy this bag lightly used from a gear exchange shop. I've used this bag many times in the summer at elevations of 9,000 and below and it has been sufficient and cozy. Recently took it for a late season hike up to deer lakes, 11,400 ft. It got down to around freezing at night and even with fleece pants, wool socks and a down sweater on, I couldn't get warm enough to fall asleep. Finally traded bags with my hubbs. He had a 20 degree synthetic bag and it was SOOO much warmer even though the temperature rating indicated it shouldn't be as warm as my B.A. I will keep this as a lightweight low elevation summertime bag but I wouldn't try getting it close to the 15 degree rating.

I have never used a bag with no insulation on the bottom, though it seems like a good way to cut down on weight. I have a rectangular Nemo pad I love already so my question is, does this bag still work with a pad that can't be slid into the bags sleeve? Or will I feel cold just placing it on top of the pad. Fyi, I am a cold sleeper and like to keep toasty. Thanks

Best Answer

Hey Donna, I have the Thermarest down version without insulation on the back and like it a lot! its pretty universal with the pads so long as they're not extra wide.

I do feel much more comfortable throwing a hot water bottle into the bag 10-20 minutes before I get into it so the sleeping pad will be warm.

Unanswered Question

Will either the regular or mummy version of the Q-core SL fit in this bag?


Absolutely adore it

  • Familiarity:I've used it once or twice and have initial impressions

I just received this in the mail, and decided to try it out. I will say, that you definitely need something such as a sleeping pad underneath; it doesn't provide sufficient support on the bottom. One of the great things about this sleeping bag, that I found, is that there is a section on the bottom where a sleeping pad can be inserted so that you aren't sliding off the pad in the middle of the night. Another great thing about this sleeping bag is that it has a nice little shaped pad for your neck so that it doesn't rub against the fabric of the bag during the night. A third wonderful thing about this item is that unlike other mummy sleeping bags, this one offers more than enough space at the bottom, so if you move around a lot while you sleep, like me, you aren't completely tied down by the fabric. One thing to mention, is that if you purchase a size petite, like I did, I would suggest buying a regular size sleeping pad, not a petite, if you would like to be more comfortable. Overall I found this sleeping bag 100% satisfactory.

What pad sizes work with this sleeping bag?

Pad sizes that work with each sleeping bag size:

Petite (Sleeping Bag): 20"x66" or 51cm x 168cm

Regular (Sleeping Bag): 20"x72" or 51cm x 183cm

I have the Roxy Ann in the Petite. The specs say 20X66 and the specs for the Therm-a-Rest NeoAir Xlite Woman's pad are the same. Could this pad be used even though it is not square? If not could you recommend a similar square pad that is around the same weight? I'm doing a AT thru hike in the spring so I need a well made light pad. No monster 1.5 pounders! Thanks!


Won me over

  • Familiarity:I've used it several times

I wasn't sure what to make of the Big Agnes sleep system, but the Roxy Ann won me over. It had much more shoulder room than the Marmot women-specific bag I tried. I can turn on my side in it, and still feel gently cocooned. The Big Agnes system puts no down underneath where you'll be slipping your sleeping pad in. It sounded like trouble to me, but I've decided it's pretty clever. I bought the Big Agnes Insulated -Core, and the system is perfect for me. I sleep better in this setup than on my beloved carcamping Thermarest, simply because you can't slide off of a sleeping pad that is in a sleeve in your bag. The higher "rails" on the Q-Core also form a comforting cradle, making the whole setup more comfortable than I could ever imagine a backpacking sleep set up to be.
