Re: Choosing a down bag

With my 2011 Marmot Pinnacle sleeping bag shell disintegrating and plastered with Gorilla Tape on tears, did my homework yesterday online for current down sleeping bags in the 5F>20F range so this morning ordered from REI this below Aya 15 women's model by Nemo, a $390 list price model. REI had it on sale for $293 and I then received a special 20% online purchase code discount plus a 10% REI membership discount plus had $30 of REI credit so only $225 after taxes.

Perusing all the websites and information noticed there are significant reasons to be very careful selecting down sleeping bags in this online era as there are many products with mediocre specs being sold for high prices mixed in with valid pricing. Especially important to look at actual down fill weights, fill power ratings, and industry standardized temperature ratings versus manufacturer ratings. Probably many sleeping bags are sold in sporting goods stores by look and strong bright colors without people understanding product issues.

The women's size is fine since I am just a thin 5'6". The light metallic color might as well be gender neutral and will allow some modest custom marker artwork. Have a rotisserie sleeping style usually turning each time I wake up and most often just use sleeping bags blanket style while sleeping atop my short Z Lite pad until wee hours when I might get inside and zip up. Will report back here after it gets shipped and use it a bit.

I just received my Western Mountaineering Ultralite, obtained via our own Maverick. ... ultralite/

Full-length #5 YKK Zipper
Full Down Collar
5 1/4″ Spacing/Continuous Baffles
59″/38″ Shoulder/Foot Girth
5″ Loft, 20° F
16 oz. Down Fill
1 lb. 13 oz. Total Weight

It is a beautifully crafted piece of gear. I particularly like the taping around the zipper which prevents it from ever snagging. It is noticeably lighter than my old bag, and comes with a sturdy storage bag and a stuff sack. I will let you know how it performs after a summer of backpacking!

Yes, please let us know what your experience is with this sleeping bag. Being a cold sleeper, I am particularly interested in what you have to say about how warm you found this bag to be at or near 20 degrees (or whatever the coldest temperature is when you are using it).
