Forget about dropping half your paycheck on a sleeping bag. The ALPS Mountaineering 35-Degree Blue Springs Sleeping Bag is a true 3-season bag with offset baffles, double-sided closure, and an included compression sack. Best of all, the Blue Springs won't gobble your food budget for the week, so you can stay out of the ramen noodle aisle and head straight for the steaks.

  • 35-degree rating makes the Blue Springs appropriate for mid-spring to mid-fall camping
  • Siliconized finish on the insulation fibers helps maintain loft
  • 2-layer offset baffles eliminate cold spots
  • Synthetic insulation retains insulating properties when wet
  • Mummy shape insulates more efficiently and packs to a smaller size than a rectangular bag
  • Tough 210T nylon shell resists abrasion
  • Soft 210T polyester lining wicks moisture
  • Structured, insulated hood stands up on its own and has a hook-and-loop tab to prevent involuntary unzipping
  • Full-length zip on one side, half-length zip on the other side allows you to quickly vent or sit up comfortably
  • Regular bag is less than 3 pounds
  • Compression stuff sack included

Great weekend

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

Took this baby out to the Coal Pits in Zion. early may. it packed up small and we carried more than we needed for the weekend :) super comfy bag. i love the double zipper feature. zipper moved great, no snags and i was able to cross my leg because of the great width of this bag

Ole Cliche: It Is What It Is.

  • Familiarity: I've put it through the wringer

It's a great bag for mild nights. I've used this several nights on the Appalachian Trail and on the Linville Gorge Loop. It kept me warm when needed. I would recommend it for weekend hikes and/or if you're pack is at least 44 Liters or more. Depending on the compression bag, it will compress down to a size slightly larger than a football or a bowling ball. My bag is a long, so smaller sizes will compress much better. It's a good quality bag, the only issues I have is that the zipper sometimes snags and I wouldn't use it for long distance hiking. That being said, I still use this regularly and the price is unbelievable!

Great bag!

  • Familiarity: I've used it several times

Love this bag. It is pretty light weight but is also warm. I have used it a couple times so far and the only time I was a little bit cold was during a night up in the Uinta mountains. It is also super comfortable and I love the fact that the side opposite the zipper unzips a few inches so you don't get that claustrophobic feeling. Great bag.

Is this bag really only 21 oz? What are the dimensions when stuffed?

Hi Sheila,

Sorry to burst your bubble. I was curious because 21 oz is the weight of many high end down bags. It looks like an error on BC's part. I just checked the Alps website and its 21 oz fill weight meaning the amount of insulation in the bag. The actual weight itself is 2 lbs 11 oz.. There is no information on the stuffed dimensions that I could find. But the post below had the same question and Wayne said that the stuff sack dimensions are 17.3 x 7 inches. Hope this helps.

Tia, The fill weight is 1.3 pounds, the actual bag weight is 2lb 11oz. I'll put in a note to have that changed.

Can you zip 2 of these bags together?

Unfortunately, no.
Mummy bags are designed to be more form fitting than a "square" bag. They typically only have a 3/4 length zip on one side.
Look at standard rectangular/square bags for ones that can zip together.
