Description

A super-warm bag just for the ladies.

Everybody knows that xenon gas is being used as the propellant for ion thrusters in spaceships, but few people are aware that it's also used as the insulator in Marmot's 15-Degree Down Women's Xenon Sleeping Bag. What's that, science master? Fine, it isn't actually, but the 850-fill goose down that Marmot chose is a way better insulator anyway. Plus, when you combine with a DWR-coated Pertex Microlight shell, the whole bag weighs a lightweight 2lbs 9oz, so it won't sit like a boulder in your backpack―making it perfect for all spring, fall, and moderate winter trips.

The insulation itself is treated with Down Defender, a water-repellent coating that helps it maintain its loft and warmth, even if it does get a little bit wet; there's actually extra down packed into key areas, making sure you don't have to deal with cold spots. There are strategically-placed stretchy baffles as well, which move with you to keep you comfortable while you're dreaming and, since drafts have ruined many an otherwise cozy night, the Xenon has an insulated draft tube, collar, and face muff to keep all the cold air out and the warm air in.

  • EN comfort rating of 19 degrees
  • 850-fill down with Down Defender water-resistant treatment
  • Women's-specific fit with more down in key areas
  • Mummy bag with trapezoidal footbox construction
  • Pertex Microlight nylon ripstop fabric with DWR treatment
  • Six-baffle Nautilus drawcord hood with insulated collar and draft tube
  • Stretch tricot baffles and head and foot
  • Stuff and storage sack included

So hot...zipper stuck...no escape!

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

I did all my backpacking this year with a 3.5lb synthetic bag from the 90's, it was so worn and flat that I packed a 1lb fleece blanket too and still froze. I put my research hat on and decided to buy a good down sleeping bag. I wasn't fooling around, I figured this would be my last sleeping bag purchase so I considered serious, expensive options like Western Mountaineering or Feathered Friends.
I settled on the Marmot Xenon 15 because of the weight to temperature rating ratio and the short 5'6" length. I really like the color, usually I deplore the pink that's slathered onto women's gear but I'm forced to admit that the Xenon is a foxy, good-lookin' bag. The stuff sack a tight fit, I'm replacing it with a larger compression bag. The storage bag is great, mesh and no compression, the Marmot should last forever kept this way.
I spent a few nights using it in my buddies' camper so I haven't given it a true test but I have some initial impressions. My ass was an ICE CUBE when I crawled in the first night, however, after 1/2 an hour, I had to unzip the bag. The 850 goose down thawed my butt (and I cannot lie). I'm pretty thrilled with the warmth factor, I'm anxious to try the Xenon in some truly crappy weather because I think it'll perform well.
Of course, there is a downside. The zipper on this fluffy, purple beast inhales sleeping bag no matter the direction of pull. Whether zipping-up to thaw glacial glutes or unzipping to escape your sweaty, taffeta prison, the Xenon 15 is a real pain in the ass to operate. At $400+, I think the single moving part should function perfectly and maybe give me a foot rub. I got a screamin' 1/2 price deal but if I'd paid retail, I would consider a return.
If I go snowshoeing with 2 friends and a couple of fifths, I'm pretty sure I won't freeze to death but I AM worried that the zipper will tear a hole in the bag if not another dimension.

Marmot makes clouds

  • Familiarity: I gave it as a gift

I've been a Marmot fan for several years. All the Marmot gear I've owned and used has been great with certainly no exception to their sleeping bags. I will not get into the history of Marmot down bags, but let me just say they are innovators and stand behind their products. They are also the oldest customer of W.L. Gore in the world outdoor market. Now onto the bag...
I wanted to get a women's specific bag for my gf and ran across this. All I can say is wow! She absolutely loves it! The EN rating for this bag is 19 F which is equivalent to my Lithium O F.
She tested it on a trip to Palo Duro Canyon in which the temps dropped into the lower teens with high winds. She never complained and was in fact warm.
