Size guide

Why we made it

Here to save the day, the HIRO trousers offer the ultimate in movement and breathability for climbing and other intense activities.

If 3RD ROCK’s Strider trousers were to meet the old-school Ronhills, the HIRO would be their lovechild! Stretchy and moisture controlling, the HIRO are flexible slim fit trousers that are built to last, with bum and knee patches for reinforcement. An elasticated waistband brings pure comfort while articulated knees give extra movement.

Why we love it

Elasticated waistband with internal puller cord to keep you secure

Deep pockets and flat zips that don't catch on things

Made from recycled post-consumer plastic these shorts keep you and your conscience feeling great, and in a fantastic range of colours you’ll look great too

2 colours to choose from - classic black or splash blue
