Black and grey denim with more give and a softer hand than our canvas. Breaks in fast, moves easy, still built for the wall.
Two denims, one pant
Flexible black denim where you move, structured grey denim where it holds. Give and shape in the same pair.
Reinforced where pants blow out
Double-layer seat and knees. The first place most pants fail. The last place these will.
Cinch it or drop it
Elastic ankle cuffs. Tight for the wall, loose for the street. Your call.
Handmade in Barcelona
Cut and sewn by hand in small runs. Backed for life against our own mistakes.
Made by hand. Worn on the wall.
We sweat the stitches. You just climb.
22 pieces. One pair of hands.
In Barcelona, from the first cut to the last fold. So out there, the only thing on your mind is the next move.
If a seam ever gives up before you do, it's on us. For life.

Absolutely love these pants! They helped me with sizing on Instagram, helped me with a change in my order and they came super fast. They are super comfortable and light weight. Highly recommend! (Picture is a Size L)

Super cute and very forgiving in the waist. I was worried about them moving with my body, but I can do everything I want in them! Definitely going to be my go to winter climbing pants!
Also, definitely cute enough to wear out to the bar! -
Amazing quality and design; the size chart was very accurate. However, it did take 45 days for the pants to arrive in Norway.

I've worn a lot of different climbing pants/outdoor pants. I've always been a multipurpose user, these pants are functional in the outdoor space, but also when I want to put an outfit together they work really well. Material is great, colors are wonderful, craftsmanship is top notch. Gonna be ordering all the colors ASAP

I got an XS I'm 5'6 and it fit really nice, the way you can clip the pants at the bottom is cool, they're light and breathable, other than that they just look sick.

The color is perfect, the texture, the material, everything is great and of very good quality!!

Best climbing pants I've owned. Super comfortable, I've been using them for bouldering sessions and the fabric feels strong but flexible at the same time. You can tell the quality jut by wearing them.
