John Matusiewiczwrote a review of Rab MeCo 120 T-Shirt - Men's on October 12, 2015
Familiarity: I've put it through the wringer
Fit: True to size
I read about the benefits of merino blends over 100% merino and got this t-shirt to see if it lived up to all of the hype - I was not disappointed. Everything they say is true; it's lighter, dries faster, and is more durable than 100% merino while still retaining its natural odor inhibiting properties. I'm definitely impressed.
I've used it for running, hiking, climbing and hunting and it has been flawless. It's very comfortable, and I would rate it as an "athletic" fit. I wear a large in most shirts (42" chest, broad shoulders/athletic build) and this fits just the way I think a baselayer should - close to the body without bunching-up anywhere and enough length to tuck it into your pants when necessary without worrying about it pulling out.
I'll be looking to replace all of my pure merino baselayers with MeCo as soon as funds allow - It's that good.
