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?

Don’t waste your money

Comfy enough, but I bought 4 pairs and all of them wore away to nothing in the crotch area in under a year. $180 for 10-12 month of wear is utterly ridiculous. Find a more durable product or one with a better warranty.

We are so glad to hear that you found the boxers comfortable, but we are truly sorry to learn about the durability issues and crotch wear you experienced across your pairs. Wearing through in under a year is certainly not the level of performance or quality we aim to deliver.

We strictly stand behind our gear and want to make this right for you. All of our apparel is backed by a 1-Year Warranty against material and manufacturing defects, and registering your gear extends that coverage to 2 years.

Please reach out to our Customer Care team directly at info@minus33.com with your order details, or submit a quick claim on our Warranty Authorization Page. We would be more than happy to inspect your pairs and get defect replacements sorted out for you right away.

We really appreciate your feedback and look forward to helping you out!

Very Comfortable boxers

These Wool Boxer Shorts are soft and comfortable. I like that the seams go crosswise instead of front to back. The material is light and airy to the point that you barely know that you're wearing them. Now, with the exception of pants, my entire wardrobe consists of Minus33 apparel. Been wearing Minus33 exclusively for over 5 years now and they don't disappoint. Great value for the cost and you can wear any of their items for weeks on end.

Best I've ever worn

I am a bit of an underwear snob. REI used to make my favorite, but I can't find them anymore. Bought these to try and out and they are absolutely fantastic. Superlight and love them.

We take pride in creating high-quality and comfortable products for our customers. Thank you for your support and for taking the time to leave a review. Happy adventuring!

Great underwear

I’ve used other brands of wool boxers and these are by far my favorite. They’re well made, comfortable and sized perfectly. Being Wolverino I expect them to last longer than the regular wool ones. I recommend these boxers without reservation.

Hi Bob,

Thank you so much for taking the time to leave a review for our Micro Weight Men's Wool Boxer Shorts in Woolverino. We are thrilled to hear that they are your favorite among other wool boxers you have tried. Our team takes great pride in creating well-made and comfortable products, and we are happy to hear that they have met your expectations.

Light and comfortable. Only complaint is no button on the fly. Or possibly sewn tighter fly hole

Nathan,

We apologize for the inconvenience regarding the lack of a button on the fly or a tighter fly hole. We will definitely take your suggestion into consideration for future improvements.

Not a lot of alternatives, good wool but elastic gives way

First, there is basically only one other company that does proper boxers made of wool, basically every other one is boxer briefs. So if you're a 100% boxers person like me, you don't got a lot of options (it's either this or woolX). It's good quality wool blend with high wool %age...so why 2 star? Well, the elastic gives way. Slowly at first and by the 1 year mark it's gotten to the point that it's completely unwearable. I should have caught it and exchanged months ago when I had the chance, but at the time it wasn't so bad.

Tj,

Thank you for taking the time to leave a review for our Micro Weight Woolverino Men's Wool Boxer Shorts. We appreciate your feedback and are sorry to hear that you have experienced issues with the elastic giving way. We take the quality of our products seriously and will definitely look into this matter further. Please don't hesitate to reach out to our customer service team for assistance with an exchange, warranty claim or any other concerns you may have. We value your loyalty and hope to continue providing you with high-quality wool products in the future. Thank you again for your feedback.

They are perfect as is.

I agree with a previous reviewer who wrote that they were perfect as is, and that no improvements are necessary. However I would appreciate the option of the same design, but with thicker wool/material.

DM,

Thank you for taking the time to provide us with your feedback, it is greatly appreciated! We are happy to hear that you are satisfied with the product's design and performance. I will also forward your suggestion for a heavier weight over to our product development team to be considered for the future!

Thank you!

Great sleeping shorts for gals

I'm female, and I bought a pair of these boxer shorts for sleeping. They are featherweight comfortable, they don't bind and they are very lightweight for travel. I love them, and I'll be buying another pair. One thought: I bought a Medium. I will buy my next pair in a Large. If the guy's Medium is JUST right for me, a not-very-large woman (5 feet, 5.5 inches tall, Size Small or Size 6 pants), then these must run small for men. The Medium definitely fits, but if you like a looser fit, a Large may be the better pick. But in every other way, I think I have solved my long quest for comfortable sleepwear that gives me more breathing room than traditional women's pajamas.

Darryl,

We are pleased to hear comfortable you find your Minus33 boxers to sleep in. Thank you for the great review and happy snoozing!

These boxers are lightweight and sizing is right on. I have not had a chance to use them on a multi day hike yet but from continual daily use now, they appear that they will work just fine.

Best Under $50

I purchased 3 pairs of under $50 boxers at the same time in mid-2021. The Minus 33 are the most true to size and stretch out less than the others. Will be buying more!
