Aenergy FL T-Shirt—light, technical first layer for ultimate performance
What Our Gearhead® Experts Are Saying:
"This tee is perfect for high-output days. It’s so lightweight and breathable, it almost feels like you’re not even wearing it. I especially like the mesh panels and HeiQ Fresh treatment—it keeps me cool and stink-free no matter how hard I’m pushing."
We’re always on the move, whether it’s a summit push or a sunrise run. That’s why the Mammut Aenergy FL T-Shirt is a game-changer. Its ultralight construction and body-mapped mesh ventilation zones let us stay cool and dry even on the hottest ascents. Treated with HeiQ Fresh to keep those post-adventure odors at bay, it’s built for the long haul.
The athletic fit hugs close but never restricts, moving seamlessly with us as we climb, trek, or chase new personal records. Reflective details keep us visible when the light fades, and the bluesign®-approved recycled polyester adds an extra dose of feel-good. It’s the tee that matches our pace and our passion for the outdoors.

Amazing sweat wicking but awkward fit
The color is great, the build quality is great, the function is amazing. super breathable, extremely light, holds up in washes. the only thing I wish was different was the fit. I know it's a close to the skin athletic fit but the armpit section doesn't fit me like a lot of my same sized/same function shirts. not as comfortable because it's really close to my armpits and I'm fairly slender so it's not my first pick, but if it's really hot out and I'm sweating a lot I will pick it up.

Love the fit but the tags are so annoying and itchy!
Love the T-shirt, but don't love Mammut's recent change from printed tags to sewing rough, itchy tags in the neck line that are impossible to separate out without damaging the stitching of the jacket. At least put the tags on the waist line of the jacket/shirt and not the neck!

Thin, light shirt for high intensity workouts
This shirt is quite easily the lightest workout shirt I have encountered. Hot weather is where this shirt is best suited. Still a worthwhile purchase, only reasons this shirt gets 4 stars and not 5 is because it does run a bit small and the thinness means you have to be more careful not to snag or tear it compared to other shirts.

Very light and comfortable
Excellent shirt for warm weather or working out. The cut is athletic but not overly fitted. Definitely a fan of this shirt for gym days or warm weather cragging. Material feels good. I am 5'10", 175lbs and happy with size Large.
