Columbia Sportswear Mountain Tech III S/S Top Reviews:


I have 3 of these shirts now (albeit older versions - as far as I can tell, not much has changed), and they're my go to shirt for traveling, casual summer hiking, occasional winter hiking, and to wear on hot summer days.
I brought two of them with me to Japan last summer and the shirts easily dried overnight on a clothesline despite the near 100% humidity. The shirts are quite for outdoor activities, but they have a casual enough appearance that I don't mind wearing them to school, especially on hot days.
While the Mountain Tech is lightweight compared to a regular cotton t-shirt, it is heavier than some other tech style shirts (the Stoic Breathe 90 is significantly lighter), and as such, I tend to use other shirts for my high high endurance activities (trail running, hard hikes, etc), although, the Mountain Tech will certainly get the job done. I've wound up wearing this shirt on a lot of rock climbs and the fact that it's a bit thicker I think has allowed it to hold up well to abrasion.
I'm 5'7", 155 lbs and the medium fits me well, but is just slightly loose. Which makes it perfect to wear casually, but still fine to wear on the trail.

This is one of my favorite warm weather shirts. The "polyester jersey"material in my Abyss (dark blue) shirt feels and looks great. Columbia says the fit is "Active: Body skimming fit with end-use mobility in mind". They also say that users have rated the size as "fits slightly small". I agree... For me, some t-shirts fit great in medium, while others need to be large. This shirt is definitely a large. Mine weighs in at 6.65 oz. Recommended.

Its hard to beat the value with Columbia's active tees. Its got the technology you'll find in pricer shirts from other brands and does just as good of a job. Like others mentioned, it is an athletic fit. So if you've got a sweet beer gut, size up if you don't want to flaunt it.

Honestly Columbia makes a great hiking shirt for the price. Really light weight, breathable, quick drying, and soft. While the colors are accurate, the sizing is a tad off. Although it is intended to be an active fit (form fitting), I would recommend sizing up one size.

This was a Christmas gift for my dad - he wears these shirts all the time. These are especially great for sweaty Texas summers. Lightweight and sporty and they look nicer than your average T-shirt.

it's the everyday T that has so much more. this T protects from UV bombardment, fights the funk and moves with the body so easily.

This is a good shirt. Comfortable, light and cool. They run a little bit smaller than I anticipated.
