Undertac Underwear are the best men's boxer brief on the market. Originally designed for Special Forces Operators in dangerous environments these will work perfectly whether you're on a mission or flipping flapjacks. Made from modal they are anti-bacterial, moisture wicking, and they don't pill like cotton. So they'll have you feeling cool, comfortable, and dry all day long. Oh, and they're also super soft! Due to our ambidextrous (yeah... we even thought about the lefties) Quick Release Fly you don't have to worry about moving your carry piece or reaching in up to your elbow when nature calls. The INFANTRY tag on the back of the waistband is what truly makes this tactical underwear, it's the Escape and Evasion Pocket! The top is open to allow covert carry of a handcuff key, ceramic blade, razor blade, kevlar string, or a few $100 bills, which makes them perfect for travel. Item retrieval is a one-finger job and the pocket, even when full, appears only as a label.

We may have forgotten to mention, Modal comes from sustainably harvested beech trees. So I guess you could say we care about the environment. It is biodegradable and eco-friendly. Roll with Undertac, we got you covered.

Very good!

Works exactly as you advertise! Biggest plus for me is no wedgies as with other underwear I've tried! 😆

Hi Steve! 😊 Thanks a ton for the awesome 5-star review! We're thrilled that the Infantry briefs are working out great and that you're spared the wedgies! 😂 If you ever need anything or have more feedback, don't hesitate to reach out.

Highly recommended!

Comfortable, breathable, form-fitting but not restrictive…I should’ve bought these ages ago! Great prices and fast delivery.

Protect your family jewels like you would your home!

Best underwear I’ve ever worn. Fits good, cool, and no rub.

Great!!

Great boxer briefs-extremely comfortable!
Tried a pair based on Kyle Serafins podcast
recs and I’m hooked.

Thanks, Randal! Huge thanks for giving us a shot after hearing about us on Kyle's show. We're glad the Infantry lived up to the hype. Welcome to the Sierra Whiskey Co. family—we appreciate your support!

Great gift and fast shipping!!

Good comfortable fit all day long.

They are very well made. I just don't like how they bunch up and right up my leg around my nuts. Still top notch though

All day comfort ! 0 Swamp A@#

That’s the mission
All-day comfort, zero BS.

Perfect all around

Quick delivery, great product, and I will probably be ordering more soon.

Arrived as described

Fit fine, need to take a sharpie to the glaring back logo tag as well as peel off the logo on the leg. Prefer the waist band if the wording was on the inside of the band.

Bought these for my son so can't really say but i know he loves them! I was very impressed with ...

Best Underwear Period

Been wearing these for a couple of years now and I can say they're the best underwear on the market for active dudes. The junk flap design makes way more sense than the normal side one. Makes it a little tricky pulling it out through your fly when you're carrying appendix but that's it.

They are crazy soft and comfortable. They do wear out quicker but well worth the cost of replacement and that's why I have them on a monthly subscription.

Thanks so much for the awesome review, we really appreciate you sticking with us these past couple of years. You're spot-on about the comfort/durability tradeoff. We’ve tested a ton of fabric combinations over the years, and while we’d love to make them indestructible, that usually means sacrificing the softness and performance guys love. Our Recon line is about as bombproof as it gets, but it’s a different material and serves a different purpose.

Feedback like yours is invaluable. It helps us keep refining the design and pushing toward that perfect balance. We truly appreciate your support! We’ll keep working hard to make sure Undertac stays the best gear in your lineup.

Thanks again for being part of the mission. Stay awesome!

the order showed up in a couple of days just as promised

this is my third time ordering the Infantry boxer brief I ordered some from an advertisement and liked them so ordered more to only use this boxer they are the only thing I like to where

Hi Kent! 😊 Thanks for the amazing 5-star review! We're thrilled to hear that the Infantry briefs are your top choice and that you've loved them so much you keep coming back for more. If you ever have any questions or need assistance, we're just a message away!

Love the underwear.

Great fit. They shrink just a little. Size up.

Good but sizing is off.

Good quality but your sizing chart is WAY off. I should need a L according to the chart but had to get a XXL instead. Waste band is TOO small.

Very nice underwear

The tag should not be heavily labeled it thick and scratchy

Stretchy smooth silkiness !!

Feels fantastic on the boys and the buttocks !

Hi Perry! 😊 Thanks a ton for the fantastic review—glad to hear the Infantry briefs are keeping you comfy and happy! If there's anything more you need or if you have any updates to share, just give us a shout. Stay awesome!
