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 for canoeing!

    I recently wore these for 5 days straight on a canoe trip in Minnesota. The pants were comfortable and breathable enough to wear in the hot weather to maintain bug and sun protection, dried fast after wet-footing the portages, and held up great to mucking about in the brush for firewood and hanging the bear bag. Also, the pocket layout is great for accessing items while seated/paddling. The only minor edit I would make would be to drop the double knee another inch or so, sometimes in very flexed scenarios, I was right on the coverage edge of the double knee. I am picky about pants in the outdoors, and these are legit.

    Hi Angus,

    That's an incredible real-world test for the GTFO STRETCH WOVEN MOUNTAIN PANT-STRAIGHT - five straight days on a Minnesota canoe trip with everything from hot weather to portage wet-footing and brush bushwhacking! We're thrilled they delivered on all fronts: comfort, breathability, quick-drying performance, and durability. It's fantastic that the pocket layout worked so well for accessing gear while paddling - that kind of thoughtful functionality is exactly what we're aiming for. Your feedback about the double knee placement is really valuable too; we appreciate that level of detail from someone who's clearly picky about outdoor gear performance. Thanks for putting these through their paces and for the awesome review!

    Great pants - poor fit

    Material, pocket layout, comfort, breath

    -ability, and durability are great. Most comfortable field pant I own in terms of material comforts

    I wish they came in 36 Length - for taller guys the 34 L will fit fine in sandals, but rides high in boots.

    Great pants

    I first bought the regular GTFO pants that I wore during multiple trips in the summer. Based on how well they did, I decided to also buy the mountain pants.

    I am 5' 10" and always order size 32/32. The pants are a bit too long for me. Nothing too much but length 31 would be perfect for my height.
