Get ready for your new favorite baselayer, the Men's Smartwool Lightweight Zip T. With a 14 inch center front zip, this long sleeved next-to-skin piece is designed to be used as a cool to cold weather baselayer, or on its own during moderate to high intensity activities. Sculpted side panels eliminate side seams and reduce chafing, while enhancing the form fit of this 100% merino wool top. Flatlock seams also add to the comfort as a drop tail hem and contoured sleeve cuffs increase coverage and improve fit during exercise. The modified raglan sleeves improve range of motion and freedom, letting you concentrate on your skiing and not your gear. Toss the stinky polypro and pull on the choice of sheep, the Lightweight Zip T for men from Smartwol.

Functional Base Layer
March 30, 2012

I recently got this shirt and used it for the first time this week. My intention for this shirt is to use it as a base layer and since I am always overheating I wanted something lightweight with minimal warmth. I found the weight to be comfortable under my softshell and on its own. I have not used it long enough to know about durability, which seems to not be as good with wool compared to polyester, but nothing about the shirt led me to think it would be a problem. I really like the long body of the shirt. It easily stayed tucked in even while wearing a backpack. This makes base layers so much more comfortable that I am always surprised how many are too short. Another review recommended sizing up, I disagree. I am 6'4" and 220lbs and got my normal XL and it fits perfect. I kind of wish it had thumb loops, but I rarely use them so it is not a big deal for me.

Great Baselayer for hiking
January 19, 2012

I use this here in Pennsylvania during the colder months up in the Pocono Mtns. It is a terrific base and breaths well. Depending on conditions I only use a micro fleece on top with a light shell if necessary to cut the wind. As it warms up I loose the shell and micro. I run hot so if you do to you can get away with this solo with temps in the 40-50 range. I'm 6'3" @ 205 lbs. I love the fit of the XXL. Another great Smartwool product.

Pros: Great design, Build quality, Performance, Great value, lightweight
