CARE TIPS

CARE TIPS

Made from 100% cotton, Callo Denim

First wash = just denim & you

Raw cotton denim can release excess dye at first. Wash it alone or with dark tones to keep your Callo Pants looking fresh.

Cold & gentle is the way

A delicate cycle in cold water protects the fibers, preserves the fit, and keeps that just-made feel.

Skip softener the first time

Let the fabric breathe naturally. Softeners can trap residues from the making process.

Inside out, always

It's the easiest way to reduce fading and protect the surface from unnecessary wear.

No heat on embroidery

High heat can weaken and unravel the stitching. Treat the embroidered details like the art they are.

Size exhanges and returns

Each piece is made in small runs. We accept size exchanges and returns within 14 days of delivery. Original item must be unworn and in original condition.

Details by color

Rose Quartz — Midweight 210gsm cotton canvas in dual-tone pink.

Built with more structure and durability than Opal, offering a balanced feel between stiffness and comfort. Tough enough for repeated sessions on rock and resin, yet softens naturally with wear. Designed for year-round climbing, street use, and longer days where resistance and movement matter equally.

Details by color

Opal— Lightweight Japanese denim, ideal for warm weather or extended daytime wear. Slightly more breathable, with a softer feel from the very first climb.
