Super Comfy

I have quite a few of these and love how comfortable they are

Fit

This shirt is very comfortable and I like material. I bought LS last year and fit was good. This SS version I don't like fit. Front, shoulders and chest perfect, but the bottom part in the back rises up and looks a little wider than it should be. The e back part of the shirt seems shorter than the front, although it is not because of the cut. I will return it.

Give Us A Black Tshirt !!!!

Durable comfortable shirt especially to wear in layering. Not having an all black option is a horrible choice.

Tall Sizes Please

Please make TALL sizes! when I climb and raise my arms above my head the shirt is to short and pops out of my harness and I hate that.

A Must Have In Kit

Cool, comfortable, durable, great fit and quick drying. The Perfect hiking shirt under my Atom or my Gamma Lightweight. I don’t have enough for every day of the week, but I’m working on it.

Disappointed!

Prior to this latest "Revised" version of this shirt, the length of the short sleeves were longer which kept the shirt sleeves from riding up into your arm pits. Now this "Revised" version has made the short sleeves too short and, as a result, the sleeves won't stay down in place and they ride up your arm during any kind of activity. Please bring back the longer short sleeves and also please create some new neutral colors.

My Do Everything Shirt

This shirt is very breathable and comfortable, and I think it fits even better than the long-sleeved version. It is still slightly tight across the chest, but I really cannot find any other faults. It is perfect for hikes, jogs, or the gym. If you need a go-to shirt that you can wear anywhere, this is it.

Ok, Not Great

I use this shirt for trailrunning, so high intensity output. But it's not suitable for warm weather (+18 deg celsius). It's not that breathable and soaks up sweat easily. After getting wet, my nipples starts chafing. Fit is fine. For it's price, it lacks top tier performance!

Great Shirt But Sizing Can Be Inconsistent

The fabric is amazing for high output activity. I have 4 of these (from 2021, 2023, and 2025) that I use for running and hiking and gymming. My only complaint is that sizing can be inconsistent. I have a 2023 Cormac SS in Pytheas Heather that fits a lot tighter under the armpit. Not sure if it was just that iteration because I have another Cormac that was produced two months apart in 2023 in Arctic Silk color (also in Medium) that fits comfortably.

Needs Real Black Color.

Love the shirt. Not sure why they don't make it in a real black that doesn't show sweat.

Peace Of Mind Shirt

Recently wore this shirt to a cycling class and I will be back to purchase more. Love how the breathable lightweight material allowed me to stay cool the entire time. I didn't even have to worry about BO as it was odor resistant and continued working out with a peace in mind. The fit and airflow defiantly stand out!

Breathable And Lightweight!"

I absolutely love the material and how nicely it fits! This is a top choice for anyone seeking a breathable and lightweight tee that performs exceptionally well. Designed with the active individual in mind, this shirt offers comfort, durability, and functionality.

Cool Cormac

I wore this shirt for an intense cycling class and it was awesome! Lightweight, quick drying, loose comfortable fit. It’s perfect for exercising indoors or warm weather sports. The dark blue looks amazing!

Super Lightweight

I recently picked up this workout t-shirt and it quickly become my favorite t-shirt for workout. The fabric is lightweight, breathable, and wicks away sweat very well. It gets dry very fast, the material feels soft on the skin and doesn't chafe, it also holds up well in the wash with no fading or shrinking. Definity worth the price

Super Lightweight Workout Shirt

I love this workout Tshirt. The fabric is lightweight, breathable, and wicks away sweat really well. I am 5ft5, 150lb, and a medium size fits me very well. it snug around the shoulders and chest, but loose enough around the waist for comfort and mobility. It gets dry quickly, material is super soft on the skin, holds up well in the wash with no fading or shrinking
