Moench Light T-Shirt

Challenging hikes and long backpacking treks require the services of the Mammut Men's Moench Light T-Shirt. This tech tee features a light, sweat-wicking fabric and movement-oriented design that helps you stay cool and comfortable on the trail. Polartec Power Dry pulls sweat from your skin and dries quickly to help you beat the heat, and Mammut's Vertical Motion Technology and gusseted underarms offer an ergonomic fit for freedom of movement. Smooth flat seams won't chafe your skin under your backpack straps, and an anti-odor treatment fights off smells when you're on day three in the great outdoors.

  • Lightweight performance shirt for moving in the mountains
  • Polartec Power Dry fabric manages moisture and stretches well
  • Vertical Motion Technology for optimal mobility
  • Underarm gussets allow better range of motion
  • Anti-odor treatment wards off funky smells
  • Flat seams wear comfortably under a pack
  • UPF 50 sun protection hides skin from UV rays

Fun and comfy shirt

  • Familiarity: I gave it as a gift but have feedback to share

Got this as a gift for my dad and he loves it and wears it a lot with other mammut stuff. And I like this brand too!

Most breathable base layer I own

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: XL

I buy a lot of gear in search of that one perfect item. This shirt if one of those perfect items. Normally I wear the orange shirt (in XL - I weigh 200 lbs) in the Fall during hunting season. The color is bright so I stand out in the woods, the shirt is durable so it doesn't tear on trees when it snags (I'm looking at you, Merino Wool), and when I do sweat a lot it breathes extremely well and dries quickly.
Recently I was in VT during an early July heat wave - there is no AC in our home up there, so it was hot and muggy - 92 degrees, 85% humidity. Nothing I wore felt good - merino wool, my favorite fishing shirts, cotton... everything felt sticky and uncomfortable on my skin. Then I put the Mammut Moench shirt on to go out for a MTB ride - comfort instantly achieved. I knew the shirt was great but even I was surprised - during the next few days this shirt is the only thing I wanted to wear. Whatever magical material Mammut made this out of, it really works. I am so impressed with the shirt, I just ordered another one for running.
Odor control isn't quite as strong as merino wool, but it is still far better than just about any other nylon, anti-microbial material I've used. It is also way more breathable than any synthetic base layer I own.
One note on fit - I am normally a size Large, but European sizing tends to run a bit more on the trim side. I purchased both a Large and XL int this shirt, and wound up returning the Large. If you run between sizes I'd recommend doing the same - this is going to be your favorite new base layer, so you might as well get the sizing dialed in. Hope you all have fun out there!

Amazing baselayer

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: s

I almost wear it everyday, with excellent performance, odor control and super faster drying speed much more than before.

I will super recommend it

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.
