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.

    Good, not great!

    These pants have a lot going for them. The design is well thought out - I wasn't sure I'd like the front-oriented cargo pockets, but they are easy to access even while sitting, and the zippers work great. My biggest gripe with these is that they just didn't have much stretch at all to them. This was no secret, as the material used is shown clearly on the site as the least flexible material used by Origin, so I should have known! For comparison, my favorite flexible, active slacks with cargo pockets currently are the Barbell Apparel "Covert Pant". The ONLY reason they still top these GTFO's are because they stretch like mad - and I need that in an active style pant. As soon as Origin makes a pant like these with the stretch I'd like, I'll buy 6 on release day! If stretch isn't important to you, you'll love these!

    Hi Andrew,

    Thank you for taking the time to share your feedback about the GTFO STRETCH WOVEN MOUNTAIN PANT-STRAIGHT, and we sincerely apologize that the shrinkage after washing and the shallow back pockets have made these pants disappointing for you, especially when you're making the effort to buy American-made products.

    Your specific feedback about the pants shrinking after one wash, combined with the back pockets being too shallow to be functional, is valuable information that we'll share directly with our design and manufacturing teams to review our fabric pre-treatment processes and pocket construction specifications to ensure we're delivering the durability and practical functionality that customers should expect from performance mountain pants.

    Your insights about the pocket depth and fabric stability help us understand where we need to improve our design to deliver pants that maintain their fit and provide the reliable features that make them worth choosing American-made.

    Will they perform time will tell.

    So far I'm loving the pants. Light, strechy material. Great for hikes, camping, range and everyday wear. Pockets will print anything you put in them so if you pocket carry a ccw you can forget about it. Again great pants will get another pair in another color. American made fantastic product.
