Lightweight, high-performing, and low-maintenance is my idea of the perfect shirt.   Apparently, the folks at Smartwool have the same idea.

Their Men’s Merino 150 Baselayer shirt feels much lighter than the average cotton t-shirt I wear with jeans. Of course the fabric, a 87% merino wool/13% nylon blend, is thinner and functions much better than cotton. The top does a great job of breathing, which comes in handy when I’m running or on my bike.

I like the versatility of the Merino 150 Baselayer shirt. It’s comfortable on warm days when it prevents me from overheating, and it keeps me warm when there’s a chill post-workout and I still have to get home on my bike. Even damp from my sweat it keeps the chill out.

This top has also been my first layer for hiking and camping. Thanks to the raglan sleeves, layering and carrying a pack are comfortable: no shoulder seams! On a quick weekend trip, all I wore was my Merino 150 Baselayer shirt. I also had a long-sleeved button-down wind- and rain-resistant shirt, so I was comfortable indoors, outdoors, in the rain, in the heat, and on chilly evenings.

My travel companion was just happy that after three days the shirt still didn’t smell!
