Marmot Couloir Sleeping Bag Review

Posted in Adventure Travel, Outdoor Gear by Sarah McConkie - 05.03.2009

The last thing I want when I am sleeping in a snow cave is feeling chlosterphobic in my sleeping bag or sleeping cold.  I am looking for a warm, comfortable nights rest and the Marmot Couloir has you covered.

The Couloir has been refined to be one of my favorite four season bags on the market.  Every time I have pulled this bag from it’s stuff sack, people watch in amazement as the 800+ fill loft continues to expand.  I love the loft!  The 0 degree Celsius rating is very conservative.  I have slept is this bag comfy and warm at -10.  In the warmer months I simply unzip the bag and drape it like a blanket.  I am not typically a warm sleeper.

Marmot sleeping bags are put through the ringer at the Thelma Center in Norway for testing, and the work shows.  Marmot has kept the big picture, while not over looking the small things.   The trapezoidal footbox surrounds your feet and ankles naturally, you won’t wake up with a tangled end or your feet smashed in the corner.  The sleeping bag is designed after the human form, comfy from the feet all the way to the shoulders.  Many mummy bags are looking to cut weight by making a narrower cut bag.  The Marmot Couloir weighs in at just over 3lbs and is worth ever ounce.  Even after the drawstrings are secured I do not feel chlosterphobic in this bag.  The loft is light and the seams are non restrictive, so I do not even have to think about anything, or make adjustments, just sleep.

One my pet peeves with down goods is the loathed zipper snag.  One hard snag and you can ruin a down jacket or bag.  The Marmot Couloir has reinforced the nylon so it is virtually impossible to snag the bag.  The zippers are smooth and consistent.  I have had mine 2 years and it has not worn out and I do not get any draft coming through the hood or zipper line.

While the Marmot Couloir comes in just the one curry color, it is available in a Dryloft version (if you are in wet climates) and in a long version.  I have heard complaints from people saying their bag looks dirty when they are new.  It is the loft filling in under the translucent nylon, the bag is most likely not dirty.  I highly recommend this bag for is durability, performance to weight ratio, as well as comfort.

Features of the Marmot Couloir:

  • 800+ fill down
  • Trapezoidal footbox
  • Anatomically designed, wide shoulders, easy to grab zips
  • Hood and hood muff to prevent drafts
  • No snag zippers
  • One pocket on the interior of the bag
  • Storage sack and stuff sack included

The Marmot Couloir is a quality bag, and it will be a loss when it is removed from the market.  Buy one and take care of it.  Unless you live in the Couloir, the issue where it is going to show signs of wear is repeated washing.  I would recommend buying a liner (then you can just wash the liner and preserve the bag, I really like the Sea to Summit Coolmax liner) or wash it with a Nikwax down wash.  Nikwax is inexpensive and makes for long life.  Abrasive detergents can work their way into the nylon and weaken the barrier.  Enjoy and buy now from Backcountry.com! …now all you have to worry about are avalanches and cave ins…
