Arc'teryx  Cormac Crewneck Shirt - Men's

Obviously, it is baggier than the previous version once I put it on my body. I just got no idea of the designer, why change this tshirt in continuous three years. I bought cormac in the past three years. Everything is changing, the cut, the material and the UPF capability. My body shape is just good in size M for the past cormac. Now the new cormac is longer in length and even baggier. So I need to find a tailor to cut the length to make it fit. The only good news is the new material feels good than ever. The texture is not bad. My recommendation is you better try it before you buy.

I have 5 cormacs in total. 3 from 2024-2025 2 from this years release with the new fabric. I can say the new fabric here is so much softer and more breathable. However, it’s roomeier (bigger in medium) but it allows for more air flow and I don’t mind. The Phasic material was nice but held onto moisture for a while. The new Solotex does dry up quicker. Buuut, it lost its upf spf rating?? The last phasic was upf50 rated. These aren’t?

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.

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.

Last years version of this shirt was my favourite tech tshirt I’ve ever worn (and I’m picky!). They made the fit baggier, dropped the spf in the entire line, and the material doesn’t feel as nice on skin wearing it. This update ruined all of my favourite things I loved about this shirt, so disappointing. The Cormac line is a staple across your summer lineup, why would you make such drastic changes?

I’ve been using the Cormacs for a few years now, and the updated material is a noticeable improvement. It’s softer and has more stretch, while still feeling lightweight and breathable. The length has changed slightly compared to the previous version—it feels a bit longer—but it’s not a dealbreaker for me. Overall, it’s a solid update that builds nicely on an already reliable piece.

I've purchased many of the older Cormac shirts. I love the breathability and the old style fit me perfectly. But they've changed the fit with new style, it is a few inches longer and wider around the waist. Don't fit me nearly as well as the old style. Returning it.

Simple piece, but it hits. Breathes like it's barely there, dries fast, and doesn't turn funky after days of movement. I've worn the same one through a week of backcountry trips and it's still showing up every trip. For a t-shirt, it does a lot of work.

A really great T-shirt style shirt. Comfortable, breathable, wash and wear, light weight. Excellent for travel and everyday wear. I have several Cormac Crew shirts and live in them.

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.
