Great shirt but sizing can be inconsistent

8 days ago
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.

HI there. Thanks for your feedback on the Cormac Crew Neck Shirt SS — we're glad to hear you love it. We hear you on the colour and understand how a deeper black that hides sweat would be a useful addition. We’ll be sure to share your suggestion with the team.

Peace of mind shirt

a month ago
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!

Super lightweight

2 months ago
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
