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.

Not sure what size or fit type you need?

had to pay 10 dollars to return a 70$ shirt...

Thank you so much for sharing your experience. We truly appreciate you taking the time to let us know how things went. Customer satisfaction is incredibly important to us, and we never want anyone to feel disappointed with a return or exchange.

Just to clarify, our return policy does note that customers are responsible for return shipping, and in this case the return label cost was $7. That said, we completely understand how any unexpected fee can feel frustrating, and we’re always here to help make things easier.

Also, reaching out to us through email or chat before sending the shirt back, we could have set up an exchange for the larger size and waived the $7 return shipping fee. We’re still more than happy to do that for you by simply sending us a quick message at info@minus33.com, and we’ll take care of everything.

We appreciate you choosing Minus33, and we’d love the chance to make this right for you.

The WOOLVERINO men's t-shirt is as soft as can be

The WOOLVERINO men's t-shirt is as soft as can be. My husband, a fan of Ibex, Icebreaker, Smartwool and Madam, tells me Minus 33's micro weight shirt outdoes all of the other companies. Your product is superior.

Thank you so much for taking the time to share your feedback on our Microweight Men’s Wool T‑Shirt – Woolverino. We’re thrilled to hear that you’re enjoying the comfort and performance of our Woolverino fabric. This blend was designed to give you the best of both worlds—Merino Wool’s natural breathability and odor resistance, combined with added durability and stretch for everyday wear.

If you ever have questions about care, layering, or finding the right Minus33 gear for your next adventure, we’re always here to help. We truly appreciate your support and are glad to have you as part of the Minus33 community.

Lower quality than older cuts

Lower quality than older cuts. Not sure what they changed, but the longevity and effectiveness of the merino wool is no longer there. For the new models; after tough operations it starts to smell a bit musty and doesn’t hold up to nor wick sweat as well as they used to. Also feel a little more “plastic-y”.

Thank you for taking the time to share your feedback. We’re sorry to hear that the current Woolverino T‑shirt isn’t performing the way your older versions did. We haven’t changed the core fabric blend, but we know that even small adjustments in fit, weight, or construction can affect how a garment feels and performs in demanding conditions.

Your notes about odor retention, wicking, and the “plastic‑y” feel are especially helpful. This isn’t the experience we aim to deliver, and we’d like to take a closer look. If you’re open to it, please reach out to our team so we can review the shirt under our warranty and work toward a solution that meets your expectations.

We appreciate you being a long‑time customer and for giving us the chance to make this right. please reach out at info@minus33.com

Good product

Good product.

Thank you for the great review! We’re glad to hear you’re enjoying the Woolverino Microweight T‑shirt. Our merino wool is designed to keep you comfortable year‑round with natural moisture‑wicking, odor resistance, and temperature regulation—so it’s awesome to know it’s working well for you.

If you’re looking to round out your gear, we also make a full range of merino wool essentials, including socks, base layers, and underwear. Many customers love pairing their Woolverino shirts with our merino socks for the same benefits: breathable comfort, fast drying, and reliable performance whether you’re working hard or exploring outdoors.

Great cut!

I'm huge fan of the Woolverino shirt. These have a much more athletic cut than the 100% merino. I'd prefer a higher merino count for these, but I get that you're only going to get this type of fit and performance in a blend. The small fits perfectly at 5'8", 140lbs.

Hi Josh,

Thank you for your positive feedback! We're glad you enjoy the fit and performance of the Woolverino shirt. Your input on merino content is appreciated, and we'll keep it in mind for future designs. We appreciate your support!

Thank you for your review. We appreciate your feedback and want to make sure you have the best experience with our Woolverino products. Just a friendly reminder, our Woolverino items have an athletic fit, so if you prefer a relaxed fit, we suggest sizing up one size.

This is an amazing shirt…

This is an amazing shirt….the most comfortable I’ve ever worn. Lightweight, soft, no seams that rub - perfect. But…..pricey due to the materials, after all, this isn’t your typical Fruit of the Loom or Hanes T!
I expect it to be durable thanks the material blend, we shall see as time progresses.

I love this t shirt

I love this t shirt. I purchase this and several other items during the holiday sale. I’ve worn a lot of merino wool. The fit, finish and overall quality of the t shirt is second to none. I bought this to wear as baselayer under sweaters and shirts in our cold Minnesota winters. I’ll be buying more once spring hits.

The most comfortable T-shirt I've ever worn

The wool feels luxurious and the raglan sleeves for my broad shoulders well and free up movement without bunching up when I raise my arms. I love the navy blue, and am hoping for a forest green and burgundy so that I can add a couple more to my wardrobe.

We're so glad to hear that our Microweight T-shirt is the most comfortable one you've ever worn. We put a lot of care into selecting high-quality wool for our products. Thanks for being a part of the Minus33 Family!

Minus33 preferred over Ibex & Arcteryx.

I recently bought merino tshirts from Minus33, Ibex & Arcteryx and have enjoyed the weight, feel & cut of the Minus33 shirts over the others.

We take pride in our high-quality wool and are happy to know that it stands out amongst other brands like Ibex and Arcteryx. We appreciate your support and hope you continue to love our products.
