Leg Length

Why we made it

Our LARK trousers will quickly become your go-to trousers to wear on the move. We take organic cotton for total comfort and add a bit of elastane to give them some extra stretch. 

They are a relaxed fit trouser with a tapered leg, giving you a generous fit around the thigh. With our famous diamond cut crotch, they were designed to transition from your day to day threads to a comfortable climbing companion. You'll never want to take them off!

Whatever your gender or size, you can do everything in these trousers. The elasticated waist and belt loops make a good fit for inbetween sizes, and three different leg lengths make them even more versatile. 

Good sized pockets in the front or back give you quick storage, and the organic cotton twill has a peachy finish for comfort you won't forget.

Can't find your size? Check our AW22 Larks instead for more colours!
