Add warmth without the bulk of a fleece top when you pull on the Smartwool Men's TML Light SportKnit Half-Zip top. Made from soft, never itchy merino wool, this long underwear top has a touch of nylon and elastane for enhanced stretch. When you wear this merino wool shirt over a Next-To-Skin Smartwool base layer you'll be toasty warm in its naturally odor-controlling, moisture-managing, temperature-regulating comfort. Designed with a semi-form fitting silhouette, it has stylish contrast stitching and no shoulder seams so you can wear it comfortably under your backpack shoulder straps. Wearable in all 4 seasons, the Smartwool TML Light SportKnit Half-Zip shirt for men is perfect for the last hiking trip of the fall and a long ski tour this winter.

Does the job
October 16, 2012

I purchased this top for cycling. I live in London, UK, where the mornings can be blisteringly cold but the TML Light has kept me warn so far in October with only a light-weight waterproof on top. It can get a little damp if your perspire continually but does dry-off quickly with no bad odours. I'm 5'11'' and about 200 pounds; the XL is slightly loose but comfortable.

Pros: Great design, Build quality, Cons: slightly heavy
Comfort: 5 / 5
Quality: 5 / 5

Great purchase

This shirt fits and feels great. Insulates just enough so it's comfortable to wear both in- and outdoors. The material is of high quality and I would recommend to a friend.

Pros: Great design, Performance
