Rating: rated 5 of 5 stars

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.

With plenty of space for a third (or for extra gear) and with an indestructible design, the Marmot Thor three-person has become a go-to tent for expeditions and lengthy stays in the alpine realm.


This 3-person tent gives you the best of all worlds--massive room, bomber construction, four-season protection--and it's lightweight, too.


The Marmot Thor 3-Person 4-Season Tent has a burly six-pole design to fight off wind and snow during the roughest high-mountain storms. Designed specifically for alpine climbing and mountaineering, the Thor Tent stands strong whether you're taking on Rainer, Denali, or Aconcagua. Marmot thought ahead to storm-bound days and gave this tent the Knees Pole System to steepen the walls and increase its overall interior space.
