I was cold at Camp Verde, AZ, campground in February and the zipper snagged the nylon backing. Good for spring camping in dry weather at Havasupai Falls Campground with no tent.


  • It is warm and compacts nicely.
  • Light weight


  • Zipper snagged and couldn't geit it loose with fingers.

I decided to take advantage of a late winter snow fall one February and skied at the Flagstaff Sno-bowl. I drove to a Camp Verde camp ground that night and would sleep in the back of my S.U.V. I found myself so cold that I was starting the engine frequently to heat up the truck.

At some point the zipper snagged the backing material and it was so severe I ended up having to use a needle nose plier I found in my tool kit about an hour later. I did enjoy fresh powder the next afternoon back at Sno-bowl.

I have used this bag in the early spring and late fall and it works great here in Arizona in the 1,000-4,000 foot altitude range without a tent. Never used it in wet conditions or with a tent so I don't know about that. It seems to wash easy, compacts into the stuff bag easy. It is synthetic so no allergy issues.

Welcome to Trailspace, Dane. Thanks for sharing your first review with us. How long have you had your Optima? I'd love to see some pictures of your bag in your review, if you're willing to add them.

I stumbled onto the Moonstone brand at a "high-end" outfitter in 1990 in Boston, Mass. I have the Optima Long and Maxima Long bags, with snap-in liner. The latter is used mostly in New England winters; the former in spring and fall cool weather.

My Optima is showing its age with a couple rips on the zipper baffle this fall. Hardly a cold night in either bag.


  • Extra long length with room
  • Washes (by hand) well


  • Expensive but WORTH THE PRICE

Too bad to hear, now years later, about the closure of Moonstone.  I have been convinced more than once about the value of synthetic bags vs. down. The Moonstone bags store well loosely rolled up in storage bag and loft well.

I was sold, TWICE, on the one-piece, full length construction of these bags versus the traditional baffle construction. I made the right purchases at the right time YEARS AGO..  RIP....

This bag kept me warm for a month in Wyoming this summer. It is a great 3-season bag, and, with the 25 degree snap-in liner, it can be a great 4-season bag. I was only cold on one night, when the wind was howling at 40 mph and I was sleeping outside at 11,000 ft.

It kept me warm, in the rain (there were 15 days of rain) and the bag was a godsend.

A great bag for the three-season backpacker. An optional snap-in liner adds 25 degrees to the rating ($70). Take a serious look at this one.
