Wazzie Wool Long Sleeve


Color: Black
5 in stock

Our original Wazzie Wool is a wonder. With exceptionally high New Zealand Merino, and some added stretch, it's the perfect baselayer. It works hard at moving sweat and keeping you cool on any distance run, but is equally good at insulation and trapping body heat when you need it. A classic crew neck is combined with thumb holes to make up the sporty details.


• Thumb holes for added warmth
• Responsibly sourced
• Absorbs and wicks sweat
• Naturally water repellent
• Machine wash, tumble dry (line dry optimal)
• 25.5" body length (size 4)


• Wazzie Wool (Merino wool / spandex)

I have worn this shirt in black: in a 25k trail race, with temps swinging 15+ degrees, rain, sun and wind. On a date to a very nice restaurant, tucked into high-waisted jeans and with chunky boots. To work, under a blazer. Sledding with my kids, as the only layer under my winter jacket. Please make this in more colors, especially darker or jewel toned colors!


Love this so much that I bought two, one in the light purple-ish color and one in black—and I am not a person who typically buys things in multiples. This is soft, stretchy, and fits beautifully. I am usually a size medium and clothes and this is TTS. I wear it as a base layer under a sweater, as a workout top, or by itself. Big big win.

I was able to get one before they sold out! Love this shirt and will wear it all the time! I agree that a size down would be good as I bought the 6 and could easily wear a 4. Please make more!

Last for Years

I still have my first Wazzie Wool Long Sleeve from 2015 and it's held up great. This is a bit looser in the body so I size down as I prefer to wear this as a base layer, as opposed to over top something else. Not itchy at all, and has held up through many washes and trips through the dryer.
