A LETTER FROM OUR FOUNDER

Maps, Myths, and Mayhem

"In the summer of 1995, I wore the same pair of shorts every single day. That summer, and those shorts, felt like something straight out of The Goonies. I was 15, wild at heart, spending my days in the mountains, lakes, and rivers of Maine. We lived off brook trout, bathed in the lake, waged epic one-pump BB gun wars, and built forts deep in the woods.

For 30 years, I searched for a pair of shorts that could match the durability and feel of those originals. I never found them—so I made them. Right here in America. The fabric we invented is called ORIGIN NYLOC®." - Pete Roberts

"Back then, my ragtag crew didn’t need to be told to Get The F*** Outside. That was just life—through brutally cold winters and scorching hot summers."

THREE OPTIONS TO MATCH YOUR PACE.

GTFO WAS BORN OUTSIDE

When we set out to build the GTFO Collection, we handed it to a bunch of Gen X’ers and told them to do what they do best. They jumped out of airplanes, hiked the Appalachian Trail, hunted in the Maine mountains, and wandered the cobbled streets of Europe. We made a few tweaks, refined the fit, and built the perfect pant—one that performs day after day after day.

WATCH THE GTFO COME TO LIFE

We documented the first time we put the GTFO Pant to the test. Naturally it involved Special Forces Operators jumping out of helicopters into the remote backcountry of MOAB, UT.

ORIGIN NYLOC®

Origin NYLOC® is a proprietary 99% nylon, 1% spandex performance fabric engineered for rugged durability, lightweight comfort, and unrestricted movement. Weighing just 7.2 oz, it delivers military-grade abrasion resistance, 4-way stretch, water and odor resistance, and mil-spec reinforced stitching. Built to handle harsh conditions and high-output activity, it's designed and developed in the USA and proudly manufactured in Asheboro, North Carolina.

SECURE STORAGE

Two streamlined thigh pockets give the GTFO Mountain Pant stealth storage without the bulk. Positioned for comfort and quick access, especially when seated. Each pocket is secured with a rugged YKK zipper, keeping your essentials close and your movement unrestricted.

ENHANCED PROTECTION

The GTFO Mountain Pant is reinforced at the knees with a second layer of ORIGIN NYLOC® doubling durability right where it counts. Built to take the hits from crawling, climbing, or kneeling on unforgiving ground. And for next-level protection, each knee is designed to accommodate pad inserts for those who push even harder. (Knee pads sold separately)

Some men stay put. Others keep moving. Chasing adventure, covering ground, and navigating the unknown. If you're the latter, you need GTFO.

    All the stitches are coming out after one week of work! I thought these would be the ultimate work pants as an electrician. And I was sadly mistaken. Paying more doesnt always mean better quality. These are no different than the $30 Walmart utilty pants

    Skeptical at first

    I was skeptical about how comfortable theses pants would be at first since I'm picky about my pants I like to wear. I'll just say I'm getting more as soon as they restock my size. Lightweight and super comfortable. I am pretty active in the outdoors and I don't feel restricted at all. I did add a zipper pull to the thigh pockets since I am always in an out of my pockets alot but a piece of micro cord does the trick. Definitely worth it just like most Origin products.

    Light and Tough

    4.5 These pants are amazing.

    Super light, comfortable, yet durable.

    Go to for travel or getting out in the field.

    I haven't really beat them up but feel confident they could handle anything I'd get into.

    You'll catch yourself just rubbing the fabric.
