"So stretchy you can kick yourself square in the face" wasn’t on the design brief for the Bloc Pant but it’s true nonetheless... if you can reach...

Get into (and out of) tight spaces with the Bloc Pant. Designed for fair weather outdoor climbing and foul weather indoor bouldering to make heel hook hindrance a thing of the past. The twill fabric uses soft organic cotton with a touch of spandex, providing a frankly silly level of dynamic movement.

Just in case that wasn’t enough climbing comfort, we’ve added a diamond-shape gusseted crotch and articulated knees, allowing you to execute awkward moves with orangutan levels of limb looseness. The stretch-twill also allowed us to make the Bloc Climbing Trousers a slimmer fit than standard climbing pants, so you can still see your toes on nifty foot placements.

Climbing trousers need to be durable, especially if they’re being subjected to rough Peak District grit. Cotton is a naturally hard-wearing material and possesses inherent grip properties: useful for tackling gnarly off-width cracks, (or for by-any-means-possible climbers with notorious knees...).

A simple low-profile elastic waistband is easy to pull on and fits neatly under harnesses, and there are four jeans-style pockets for phones, guidebooks and retina-burningly bright beanies.
