Ten Thousand

Interval 5in Liner Short - Men's

What Our Gearhead® Experts Are Saying:

"These are my go-to shorts for everything—track intervals, trail sprints, strength days. The liner stays put and doesn’t ride up, the waistband is solid, and they’re breathable enough to handle seriously sweaty sessions. Total workhorse shorts that still feel premium."

From hill repeats to HIIT circuits, the Ten Thousand Interval 5in Liner Short is built to crush our toughest sessions. Lightweight, breathable, and designed for high-output movement, this short combines performance fabric with an ultra-supportive built-in liner that stays locked in place as we move.

Laser-cut ventilation keeps airflow high and sweat low, while the 4-way stretch fabric allows total freedom through every rep or stride. Two zippered pockets keep keys and cards secure, and a no-pinch waistband ensures comfort when we’re grinding through miles or reps. These are the shorts we grab when performance matters.
