Finally. The Best Shirt Is Back.

As an avid purchaser of this shirt for a decade. This is a welcome revision. Great job. Thanks for bringing back black. The collar detail is a nice touch.

Prefer The Previous Season

I purchased two Cormac short-sleeve shirts from the previous season, and they are in constant rotation. The 2026 revised version is, for me at least, much more flow-y and much less fitted. The t-shirt is objectively longer than the previous season; there is more fabric. Overall, I feel the shirt is less appropriate for technical/sporting pursuits, and more akin to a casual tshirt. I far prefer the earlier version.

Better Fit And Fabric

Revised Cormac for 2026 has an updated fit and fabric. Both are positive changes in my opinion. The neck/collar opening is slightly smaller on this version compared to the last which was too large. There is an extra few centimeters of fabric in the body length and sleeves. Fit seems more flowy but less boxy compared to the last version. I don’t see a SPF rating anymore which could be the only negative change.

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.
