Fit FAQs

What if I am between sizes?

If you are between sizes, we recommend sizing up or down based on what fit type you would prefer, and based on how you plan to wear the piece. Our knitted merino is stretchy and you could realistically go with either size. If you would prefer an Athletic fit, size down. If you prefer a Regular or Relaxed fit, size up.

Do I need to size up/down to layer?

Generally, no, you do not need to purchase a different size than normal. Our base layers are designed to fit right into your current layering system. They are also designed to work with other products in our line, too. You may wish to adjust your sizing if you plan to wear one of our garments in a way that it is not intended, if that's the case please feel free to contact our customer service team for help.

Does your clothing run true to size?

Yes, our clothing runs true to size and is sized similar to most other American brands. If a sizing discrepancy is discovered, you will see fit advice in that product's specific listing.

Perfect workout shirt

Was looking to replace my polyester workout gear with wool and was struggling to find lightweight sleeveless t-shirts until I stumbled upon this one. Perfect sizing, super comfortable, and holding up well so far.

Fantastic for everyday use

I wear this top everyday in the winter like long underwear. I like the long length that gives my whole torso a layer of warmth. It is super thin but warm. I would never wear it alone because it hugs my body so closely (and I have the largest size available). Nevertheless, I like that it is smooth which makes it easier to add a shirt or sweater on top. It is also great to sleep in because it is so long and stretchy.

Ruth,
Thank you for taking the time to leave such a positive review for our Micro Weight - Men's Wool Sleeveless Tank Top Woolverino.

We understand your concern about the snug fit, but we are glad that you appreciate the smoothness of the material for layering purposes. We hope you continue to enjoy wearing it, even as sleepwear. Thank you for choosing our product and for your support.

Kindly,

Perfect 1/2 Marathon Shirt

Quickly has become my absolute favorite running shirt. Wore the black one for a 1/2 Marathon in 66 degree 97% humidity weather and it performed perfectly. Wicked sweat, didn't get weighed down and stayed cool. Just bought the gray one and will definitely buy additional colors once made available.

Nice material, too large

The cut is good but much too large. I would have preferred an XS to be more form fitting to use as an underlayer. M 150LB 5'10" slim

Comfortable

This top is comfortable and fits great. Great for work outs as it wicks moisture from your skin. Would like to see more colors like the green on your label or maybe red and blue.

Dale,
Thank you so much for leaving us a review! The Woolverino Men's Wool Sleeveless Tank Top is a great top. We are still a small company so we love getting feedback and suggestions from our customers. Enjoy your workouts!

Cool in summer

I like the fact that they are light weight, cool for working in the garden or handling livestock. When working in the heat it doesn’t weigh you down like cotton, but breathes, unlike plastic fibers.
This are a snug fit, not loose, so i go one size up on these. Loose is my preference, on all other shirts through here i go my size, it’s just micros that i up

Mark,

We are glad to hear that you are staying cool during the summer while working in your garden or with the livestock. Owning a homestead of my own, I know how important being comfortable can be. Thank you for the great review!

Excellent shirts for warm/hot weather

I bough both colors and they are extremely breathable and ideal for hot weather areas like the Caribbean. I will definitely buy more in the future. It would be awesome if they would come in other colors other than black and silver.

Hi Jose A.

Thank you for the great review! Glad to hear you like your purchase. The Woolverino is great for keeping you cool, while giving you good range of movement.
