The Zpacks Travel & Trail Hiking Pants are built for people who live out of one pack and expect every piece of gear to earn its place. Designed for and by long-distance backpackers, they deliver the all-day comfort, mobility, and trail-tested functionality needed for months on trail, while offering the streamlined versatility minimalist travelers want for flights, city walking, and fast-moving itineraries.

Whether you are heading out for a Pacific Crest Trail thru-hike or packing a single bag for a week of travel, these are the pants you will keep reaching for. The Japanese Toray Dot Air™ Primeflex™ ripstop fabric features micro-perforations to boost airflow and speed drying, giving you breathable performance in hot weather and quick recovery after washing on the go. The stretch fabric feels relaxed and easy like your favorite lounge pants, making long flights, train rides, hostel stays, and trail days equally comfortable.

Every detail is tuned for efficient living on the move. A lightly elastic waist with a drawcord provides a clean, low-bulk fit across a range of waist sizes without needing a belt. Discreet zippered side pockets are sized for everyday essentials like a smartphone, passport, or wallet, and positioned for easy access, whether you are walking through an airport or sitting for hours in transit. All six pockets, including the hand, back, and side pockets, are mesh-lined to drain water, dry quickly, and stay ready for wherever the next leg of the trip takes you. 

Convertible Travel & Trail Hiking Pants are also available.

Kept me dry in a heavy downpour and they are so small I can pack them along just in case.

Perfect for the summer rain. Nice and light for warmer rains, and the zipper gives more room for a longer stride and some extra circulation.

The kilt packs down to nothing and very very light weight. Far better than carrying rain trousers at 5 times plus for weight. The kilt is very easy to use quickly and no need to take boots off. A great idea that keeps you dry with good quality materials and finish. Arrived quickly when ordered.
