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.

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.

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.
Good fit, feels nice, and would…….… buy again!
Thank you so much for your review! We’re thrilled to hear the Microweight Woolverino Tee fits well and feels great — that’s exactly what our Merino wool blend is designed for. The Woolverino line combines ultralight comfort with durability, moisture management, and year‑round performance, so knowing it hit the mark for you means a lot to us.
We appreciate you sharing your experience and are glad it’s a piece you’d buy again. Thanks for choosing Minus33!
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!
These T-Shirts are so comfortable! The only ones I wear!
These are the only T-Shirts I wear. Comfortable and wicks away moisture.
Order a size up as they run small
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. We hope this helps and thank you for choosing our Microweight Men's Wool T Shirt!
Best,
The Minus33 Team

The quality is excellent. Fits true to size.
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.
Used for the field, and far outperforms a regular issued style short. Bought Army green microweight wool shirt.
awesome shirt. fits perfectly! i need to pick up the other weights now
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 shirt is so comfortable, it breaths and it also keeps me warm. I will be purchasing a more of these shirts.
Feels really nice. Solid plastic fabric replacement for my athletic ambitions.
Thank you so much for your review! We're thrilled to hear that our Microweight Wool Raglan T Shirt has exceeded your expectations and has been a great replacement for your athletic needs.

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!
I recently bought merino tshirts from Minus33, Ibex & Arcteryx and have enjoyed the weight, feel & cut of the Minus33 shirts over the others.
Hi Todd,
Thank you for taking the time to write a your review. We are thrilled to hear that you are enjoying our Microweight Raglan T Shirt. 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.

Extremely comfortable and wearable
Thank you for your review! We're thrilled to hear that you find our Microweight Wool Raglan T Shirt extremely comfortable and wearable. We strive to provide high-quality and comfortable products for our customers, and we're glad to know that we hit the mark for you. Thank you for choosing Woolverino!
The sleeves appear fitted. Some merino wool t’s even a fit guys arms swim in the arm openings. Are these reasonably tight enough to fit a persons arm that hits the gym? I don’t wear tight shirts just want a fit.
Boyd,
The Woolverino Men's Wool Raglan T-Shirt is intended to have an athletic fit that is tight to the body. It is a great shirt for the gym and if you prefer a little looser, order the next size up!
