Showers Pass Apex Merino Tech T-Shirt – Great for a Broad Range of Temperatures

Drew Thayer


Showers Pass redesigned their lightweight merino wool shirt this year, also releasing a long sleeve version. These are great shirts; they’re breathable and comfortable with a form-fitting cut and are a great layer across a broad range of temperatures.

The long sleeve Showers Pass Apex Merino shirt is perfect for spring runs where the trail will be both calm and windy, this shirt is comfortable across a broad range of conditions.


A thin, tight-weave merino wool shirt is my favorite fabric for running and mountain biking, hands down. Wool is just a magical material, it wicks sweat, dries fast, and blocks a bit of wind much more than any other fabric. In Colorado our weather is very dynamic (some call it crazy), where daytime temperature swings of 40 degrees through the day and 70 degrees through the week are not uncommon. The temperature often changes 10-15 degrees over the course of a run, even more at higher altitudes. 


I love tossing on a thin merino wool shirt before heading out the door because I know I’ll be comfortable in a broad range of temperatures. For example, the long sleeve Apex shirt is good for about the 40s to the 60s, and the short sleeve from the 50s to the 90s. The ability to block a some wind also makes these shirts, especially the long sleeve, a bit of a quiver of 1 for cool-weather running and mountain biking. In moderate winds, I’m often as comfortable in just the long sleeve merino shirt as I am in a synthetic shirt and a windbreaker, simplifying my running layers.

These shirts have all the other benefits of merino. It’s the softest of the wools, so they don’t itch. The fabric repels odor quite well, good for weekend trips/ travel/ backcountry trips etc for repeat wearing. They dry really fast. These shirts also suffer the weaknesses of wool… while the weave is quite tight, any wool can catch and tear. I wouldn’t wear these shirts for rock climbing or “full contact” mountain biking, even if that contact is snaggy branches. 


Bottom Line: Really comfortable shirts with a great, form-fitting look made of high-quality tight weave merino wool. $89 $75

Drew’s love of gear is born from his life-long obsession with human-powered adventure in the mountains. On foot, on ski, on bike, and on the steep rocks, he loves exploring Colorado’s mountains through each season.
Drew brings a technical eye to gear — he’s a data scientist with a Masters’ degree in Geophysics and loves to understand the design and engineering make great gear what it is. He’s also worked in the field for many years — as a wilderness therapy field guide and a Geophysicist — and knows a thing or two about function and durability of technical equipment.
Drew tests gear in real mountain conditions, on overnight ventures whenever possible. His specialties are rock/alpine climbing and light-and-fast human-powered pursuits on ski or mountain bike. He’s ventured on exploratory climbing expeditions in Argentina, Peru, and Alaska, and completed remote technical river descents in Alaska and Colombia.
When not building statistical models and writing code, he can be found tending his garden or trying to keep up with his awesome wife.
