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.

    Great pants

    Color is a little light, I think British khaki is a better color

    Hi Michael M.,

    We're so glad the GTFO STRETCH WOVEN MOUNTAIN PANT-STRAIGHT is working great for you – a 5-star rating means the world to us! Thanks for the feedback on the color too. The British khaki is definitely a popular choice and has that deeper, richer tone that a lot of guys prefer. It's awesome that you're loving the pants overall though! We really appreciate you taking the time to share your thoughts on our American-made gear!

    Tough and Classy, not blousy

    For years I've used a competitors outdoor/rugged pants with oversized cargo pockets but was never happy with the blousy look of them; Always felt like I was wearing clown pants. I just moved up to Origin's GTFO stretch woven Mountain pant-straight and very pleased with look and fit. Tough enough for hiking off trail yet classy enough to wear in town. A Keeper.

    Caveat: The calculator recommendation used for sizing ended up being a wee bit tight in the waist and a little too long in the legs. When I changed them to my historical standard which is a 30" x 30" size, worked perfect for me. Order your standard size that works for you first, then if not fit, can easily exchange it. Origin makes the process painless.

    Greats pants, one suggestion

    Wore these recently to submit Vesper Peak here in Washington. Great pants. Held up great to the abuse of snow, ice and rocks. The one thing I kept wishing for though were some side zips to dump heat. I had the pants rolled up for the heavy inclines which caused a sunburn on my lower legs (lol). Not blaming origin at all for that. Sunscreen should have been worn. Side zips would have been magical though. Knee to hip with a mesh expansion to keep stuff out would be perfect. Attached are some photos of the pants in action!

    "Great Fit, Poor Function – Not Worth $170"

    I was really excited to try these out, and there are definitely things to like. The quality feels solid, and the material is soft and comfortable. I’m 5'7", 205 lbs, and the 36x32 fit me perfectly. They move well and feel they would be great for hiking or pairing with a flannel in the fall.

    But for $170, I expected more—especially in the functionality department.

    The biggest letdown is the rear pockets. While they’re a bit deeper than average, they have no zippers or closure system and are so loose that they’re virtually useless for securing anything. Wallet? Phone? Forget it—those have to go in the front pockets or awkwardly in the front thigh pockets, which is not ideal while hiking.

    Speaking of front pockets, they’re also on the lighter, looser side and don’t offer much security or structure. There’s no reinforced material or design consideration for carrying a knife either, which seems like a miss for something branded as a "mountain" pant.

    Bonus frustration: It’s also pretty frustrating that Origin releases these in such limited quantities. I wanted to grab a pair in Olive as well, but it’s been out of stock for weeks. For a premium-priced product, availability shouldn’t feel like chasing a limited drop.

    Bottom line: while the fabric and fit are excellent, the lack of pocket security and functionality is a deal-breaker at this price point. These could’ve been an instant favorite with a few smart upgrades, but for now, they feel overpriced for what you don’t get.

    Hi Rob M.,

    Thank you for your candid feedback on our GTFO STRETCH WOVEN MOUNTAIN PANT-STRAIGHT. We're genuinely sorry to hear about the functionality issues you've experienced, especially with the pockets.

    We understand your disappointment that the rear pockets lack closures and the front pockets don't securely hold essentials like your wallet and phone. Your point about the absence of a reinforced design for carrying a knife is also well-received. These are crucial details for outdoor gear, and we agree that these pants fall short of the practical functionality you expect from a mountain pant at this price point.

    While we appreciate your positive comments on the fabric quality, comfort, and fit, we know these aspects don't make up for the fundamental limitations that make the pants impractical for their intended use. The lack of secure storage in a premium-priced mountain pant is a serious concern regarding our design priorities, and we're taking it very seriously.

    Your detailed feedback on the pocket issues and suggestions for improvements are invaluable and will directly guide our design efforts for future versions. We also hear your frustration about product availability; improving consistent stock levels is something we're actively working on.

    We aim to deliver products that offer both an excellent fit and practical functionality worthy of your investment
