The Alpinist 2P is Marmot’s answer to a lightweight, four-season, dynamic duo’s formidable mountaineer liar that pitches in a pinch when something ominous begins to form in the surrounding skies. This single-walled tent has “Membrain Assault” technology built in to the fabric, which is made of a denier polyester blend and is fully taped at the seams to ward against brazen rain and snow, as well as tumultuous winds. A hearty floor constructed of denier and polyester with a 5,000 mm waterproof coating protects against moisture from getting on gear and sleeping bags inside. A clever partial-pole and bent knee design renders it a super-solid structure for windswept terrain. The adjustable ventilation system and flap makes it also a suitable tent for summer conditions as well. The removable vestibule is key for minimalists who care about every ounce they pack.

Very easy tent. Quick setup. Tough build. Short on vestibule.


  • Quick dry set up even in rain
  • Great vapor control


  • Nearly useless vestibule
  • Very exposed to rain when entering and exiting

This tent is super fast and easy to set up, even in rain. Not a drop gets inside if done properly. Great ventilation system. 

The one drawback for me is the vestibule. It is very small, and provides no protection from rain when entering and exiting the tent. I'm still trying to figure out how to even keep a pair of boots out there dry. Specs say there's eight square feet, seems more like eight square inches. 

A lightweight vestibule extension would take this tent right over the top.  I'm working on making my own.

This isn't so much of a review as it is a general observation and response to the first comment above. As an experienced camper, it is my humble opinion that before you pitch your tent for the very first time out in the field or on the mountain that you take it upon yourself to seal all the seams throughout with a reputable brand of "seam sealer," and let the tent stand for 24 hours or so to let the sealer cure.

Nearly any tent, regardless of its cost, will leak at the seams if it is not properly seam sealed. Some manufacturers make the claim that they seam seal their tents, but it is still highly recommended that you seam seal the tent yourself to ensure it will not let you down in the event a tent manufacturer did a shoddy job on the sealing.

Here's a few of the brand name seam sealers out on the market: 3M, McNett, Aquaseal, iosso, and Evercoat.

And, here's a little tip as far as the application goes — pitch your tent first and then seal the seams, as some of the sealers can be pretty sticky. If the nylon material isn't stretched out it can have the effect of gluing together where it shouldn't.

I bought this "expedition tent" to keep us warm and dry. It failed on both those requirements. It was quick and easy to set up under wet conditions. Last month in June, I went camping on the Temperance river in the North Shore, Minnesota. The tent sides got everything wet even after using waterproof ground sheet as the sides at the bottom leaks.

We were freezing all night even with Thermarest mats and down bags. We finally slept after first sunlight as we had stayed awake all night.

No more Marmot tents for me! I am really surprised at the poor quality of this tent after spending 500 dollars and I trusted the market name of Marmot.
