It’s all about the fit, premium fabrics and real size craftsmanship. We use Lenzing Modal® (made of 100% natural beechwood) which is anti-microbial (minimizes stink), manages moisture and keeps you cool. When mixed with a long staple cotton it creates a plush, more luxurious feel.  Seams are flat designed to not chafe, and we use different materials to keep you comfortable when you do what you do.

Born in New York. Made in Portugal.

We designed our garments right here in New York City. Our signature blends of long staple cottons, Lenzing Modal®, Nylons and Lycra, is our mix of premium fabrics that we source globally. But we sought out premiere construction from the craftsmen and women in Portugal. They have been making luxury underwear for decades. It’s part of their DNA.  Its critical for us to have that kind of heritage in those producing our garments for this brotherhood. We know you’ll agree when you feel the comfort.

Performance Daily Wear

Gruff + Tumble is designed for sport, pleasure and the daily grind. So many of our wearers love how the garments performed within these different pursuits, they enjoy mixing things up. All our styles address the fit, comfort and performance needs for real size men. So feel free to try different styles when at the gym or grinding through a full day of doing what you do. We got you covered. Variety is always the spice of life.

Empowering Ethos

Honestly, what were most proud of is creating a brand that celebrates. That supports big men everywhere.When you embrace your expression. Share your swagger. Cause we see you.

To those who suit up and show up, we give head nods. We give pounds. We solute the bruises because shit happens. Just keep it moving. Our belief is we can push each other, and our product, forward each day.

Not yet but are creating one as we speak! To us, loyalty is a two-way street. We're really striving to show ours as soon as humanly possible. Give us a minute!

We get it. You can't really know how insane our underwear feels until you try it on, and we're confident you'll agree that it's like nothing else you've ever rocked. If you disagree, we'll issue a refund or store credit for the first pair you tried on so you can try a different size or style, on us. 

 The Try Us Guarantee is available within 30 days of purchase. To claim a Try Us Guarantee, Please Contact Us with your order number or receipt to request a return by mail. 

My name is Jonathan. I started this brand with a couple of like-minded brothers who were tired of not being offered enough premium options.

So we designed some badass boxer briefs in real sizes.

As well, Gruff + Tumble is about empowerment. Gruff embodies the idea of being straight with what you want. Mean what you say and say what you mean. And Tumble symbolizes the skillful art of movement, like gymnasts – daily physical feats as awesome big men. Smooth, impressive, awesome.

Apple Pay: If you have an iPhone with Apple Pay enabled you can pay using Apple pay from either your desktop or phone. On the desktop, you must have MacOS Sierra or above; on iOS, you must be running iOS 11 or above. Apple Pay is not supported if you visited our website through an in-app browser, like Facebook's in-app browser.  

PayPal: We definitely accept PayPal on our website (desktop or mobile). The deal is, if you have a balance in your PayPal account, your PayPal balance will be used first before your backup funding source (which you will select at the time of purchase). Funds are always used from your PayPal balance first; you are not given a choice to use or not use your PayPal balance. However, the PayPal window you see may incorrectly lead you to believe you are paying from your credit card or bank first, even when you have a PayPal balance. (Even though the purchase screen does not give you an option to not use your PayPal balance, it is always used first if it exists in your account at the time of your purchase. We regret the confusion caused by this interaction with PayPal as it is out of our control.)
