The Marmot Thor 3P is one of the best 4-season expedition tents you can buy. If you're looking to do some serious winter camping then you should definitely consider purchasing this tent.


  • Spacious design
  • Quality construction
  • Easy to set up


  • A few ounces on the heavy side

Ever since I first took my Marmot Thor 3P tent up into the Alaska backcountry I have loved its solid quality design and construction. It sets up in minutes to protect you from the wind and cold. If you have the time to attach guidelines and anchors then the Marmot Thor can turn into an impenetranable shelter in the harshest blizzard conditions. 

It packs up nicely and weighs in at around 9 lbs. Although you could cram 3 adults in the tent under austere conditions, it comfortably houses 2 adults with some additonal gear. 

I've had my tent for three years and it still looks like new and is just as reliable as they day I bought it. There are a lot of great 4-season tents out there but for me, this is the last mountaineering tent I will ever buy.

The tent is lovely. We used it 100 day/nights. One trip to Burning Man at about the 40 night mark cause the fly to very significantly degrade. Marmot refused to make good on a warranty claim for repair. Nice tent. Crappy warranty support.


  • Lovely color to wake up in
  • Good ability to control temperature
  • Great size for 2 people
  • Very rain proof


  • Fly degrades in the sunlight
  • Heavy
  • Poor warranty support

Good luck setting this up in the dark until you are well practiced.

Very stable in high winds. Completely dry through powerful rainstorms.

Good adaptable ventilation.

Lots of room for two people.

A heavy tent for backpacking. Great for car camping.

Durability: Fly degraded after 40 nights. Sent it back after 100 nights and Marmot did nothing to make it right.


Welcome to Trailspace, Eric! Thanks for sharing your experience with this tent and Marmot. Did Marmot just send back your tent?

Yes, Marmot sent the fly back, un-repaired. I think it was a very reasonable warrantee request. They offered to sell me a fly for $250.
