Best Ultralight Sleeping Bag Reviews

Backcountry hikers must have an ultralight sleeping bag when adventuring in Glacier National Park’s wilderness.

The fact is many Glacier National Park hiking trails wind over towering mountain passes, down steep, dizzying slopes, and through countless valleys and other rocky terrain.

The heavier load you carry, the more troublesome the Rocky Mountain terrain will be. An ultralight sleeping bag is one of the easiest ways to cut down on additional weight, allowing you to enjoy your backpacking trip.

What’s An Ultralight Sleeping Bag?

Qualities to look for in backpacking sleeping bags are:

  • Weight - Assuming this is a summer sleeping bag, it should weigh around 1 pound. Winter sleeping bags can weigh around 3.5 pounds. If you’re trying to backpack ultralight, don’t bring the sleeping bag’s stuff sack
  • Material - Down sleeping bags are lighter than synthetic. They also are more compressible
  • Mummy style - This style sleeping bag encases you like a mummy. It’s more efficient as mummy sleeping bags form to your body and leave little room for “cold pockets” to develop
  • Half-zipper - Half-zipper sleeping bags are lighter as they shed zipper weight.

Having all the above characteristics makes a sleeping bag suitable for the backcountry. Keep in mind, if you plan to just spend your time camping in Glacier National Park’s frontcountry (aka car camping), you do not need an ultralight sleeping bag.

The Perfect Hiking Sleeping Bag

Think a backpacking sleeping bag is ideal for your Montana vacation? Depending on how light you want to go, you are going to lighten your bank account by 250-300 dollars.

Again, you don’t need a lightweight sleeping bag for car camping. You can find far cheaper sleeping bags. But for adventuring in Rocky Mountain backcountry, the best lightweight sleeping bag is the Go Lite Adrenaline 20

I personally own this sleeping bag and would not trade it for any other product out there. For backpackers, it does not get better than this:

  • It weighs a mere 1 pound, 4 ounces

  • Has a comfortable goose down fill, making it compressible and warm

  • A bottomless design that wraps under your sleeping pad to reduce weight

  • Waterproof shell and clever cut that preserves heat, but optimizes comfortability

  • Has a 20 degree temperature rating

Glacier National Park’s weather makes it likely that your pack will stay dry, encouraging the use of down sleeping bags. However, if you are hiking in wetter, warmer climates, a synthetic, hiking sleeping bag will meet your needs and Mountain Hardwear UltraLamina 15 is the best lightweight compact sleeping bag.

It's compressible, comfortable and remains fluffy after washing it numerous times. It even has a zipper on both sides so you can read or cook while in your sleeping bag.

Personally, living in Colorado and adventuring to Glacier National Park for summertime adventures, I have no need for a synthetic sleeping bag. Again, you only need a synthetic sleeping bag if you hike in wet environments, such as the Appalachian Trail.

Caring For An Ultralight Sleeping Bag

If you provide perfect care for your bag by practicing the right sleeping bag storage techniques, your bag’s lifespan will be countless seasons.

Even while on the trail, you should be conscious of:

  • Keeping out dirt and debris from your tent, reducing the likelihood it winds up in your sleeping bag

  • Crumpling it randomly when compressing it

  • Sleep with a liner to reduce the number of times it requires cleaning
