I purchased a size medium. I am 6'1" tall, weigh 145 pounds and have a 31.5 waist. In a dress shirt for work I wear a slim fit size 15.5 with a 34/35 sleeve length.
I purchased this shirt and an Icebreaker 260 Tech Long Sleeve Half Zip in order to be able to do a side by side comparison.
For quality of the shirts I feel that WoolX is easily the better of the two shirts. The Icebreaker is a 260 GM2 and the WoolX is a 230 GM2 so they are very comparable in weight. In holding up to a light and looking through the fabric toward the light, the Icebreaker is the easier of the two to see through. The feel of the fabric on the WoolX is softer and fuller. The WoolX is the lighter GM2 fabric but it just feels denser. The fit of the Icebreaker was closer to body but by no means was the WoolX baggy. The sleeve length of the Icebreaker was just a little bit longer.
When I shop for wool clothing, I shop WoolX, Icebreaker and Smart Wool. Each one has certain items that I like. Icebreaker and Smart Wool have a larger selection and specialty offerings that appeal to me for running gear.
When it comes to basic keep warm gear I feel that you simply cannot beat WoolX. The combination of quality of product, price point, speed of shipping and customer service is second to none. I have never had a WoolX purchase that I was not happy with.
When I head out to run in the coldest of the cold winter weather I assure you that my base layers are all WoolX.
The specifics of the Men’s Explore ¼ zip are simply that it is a superior quality fit and function shirt. If you are looking to buy a warm shirt for work, sports, outdoor activity or just lounging around in you cannot go wrong with this shirt. Buy with confidence and you will be happy with this product.
Two thumbs up and five stars.
