A midweight base layer for stop-and-go activities in cold weather, the Smartwool Midweight Funnel Zip top for men stays versatile with its extra tall turtleneck collar for warmth and its half-length zipper that lets heat escape when you’re sweating. Made from Smartwool’s warmest base layer merino wool (NTS Midweight 250 g/sq m), this long underwear top is non-itchy, breathable, moisture-wicking and naturally resistant to odors. Designed with a slim fit, it’s got a long torso and long sleeves with thumbholes to keep you covered when reaching up or bending over to pull on your boots. Flatlock seams eliminate chaffing and shoulder panels are designed to sit comfortably under pack straps for that long day on the cross country ski and snowshoe trails. Spend a little more time on a windy summit with the neck protection of the Smartwool Men's Midweight Funnel Zip shirt.

Excellent product
April 12, 2012

I recently bought this shirt as a base layer for various outdoor activities. I love it because it is long enough for my ape arms! In fact, the thumbholes help keep the woolen sleeves over my wrists without worrying about a jacket pulling them out of place. The fit is great and the merino wool is the best when it comes to insulation. Be sure to read the wash care instructions. It is a bit pricey but the value of merino wool is well worth it.

Pros: Great design, Build quality, Performance, Ease of use, Great value

This is a great base layer. I've worn it a few times already while running and it is great at wicking. This is a great product for its value and I would highly recommend it to anyone doing outside activities in the cold weather. The fit is great, too!

Excellent but a little loose
October 15, 2012

I love the thumb holes, the style, the feel, and the warmth. My only problem with the shirt is that I thought it was going to be a little snugger in fit since as you wear it, it tends to stretch out a little. Fits more like a regular shirt than an underlayer piece. But that said I am wearing it right now and absolutely love it. The green is bright and sharp looking!

Pros: Great design, Performance, Cons: stretches out
