You’ve found the perfect, versatile daily driver.


Made in Canada from ethically & sustainably sourced materials, this crew is designed to be the optimal general wear shirt. It’s perfectly subtle, so you can wear it on its own or layered. The stretchy, fitted and smooth bamboo is super breathable, perfect for winter and early spring.

What's different from previous versions? Same great fit now in new colours and a different external branding tag.

    Great shirt but I bought the wrong size.

    Most importantly the sleeves and body were long enough. Turns out he’s not an M anymore.....

    My Favorite Shirt

    I may be on the shorter spectrum of the tall and slim scale (6'2", 175lbs), but the LT fits like a glove. What I also like is that with my longer wing span, the sleeves don't ride half way up my forearm, as with many other shirts. The material is comfortable, soft, and doesn't give me bad body odor as with most polyester and other synthetic fabrics. Alex has personally gone above and beyond expected customer service. When there was a mix up with shipping the order, he went out of his way to rectify the problem' it helps being local. On a side note, I bought the Zod boardshorts size L back in the spring. They were too tight through the hips, and I had no problem getting them exchanged for an XL pair. Three thumbs up.

    Super Comfortable

    I'm 6'6", 250, athletic build. Bought a XXLT. Shirt fit really nice. Sleeves are a bit long but manageable.

    Another great Mac shirt

    I've bought a couple of the Mac style shirts before and this one was just as good as ever. Comfortable and fits great!
