Callo Boulder Pants
Premium climbing pants built for movement and engineered to last. Handmade in Barcelona. Designed for climbers. Baggy fit. Size down for a closer fit.
Built to move. Ready for everything.
Inspired by Japanese workwear and double-knee pants. Designed for climbers to move with you and withstand the demands of life, both indoors and out.
Each pair is handmade in our Barcelona workshop using selected premium fabrics. Not mass production. Functional craftsmanship.
Technical features
Reinforced seat and knees
High-stress areas made with durable fabric for extra longevity, using a double-texture construction that improves breathability and wear resistance. No plastics. Just structure that moves.
Adjustable elastic ankle cuffs for greater precision
Elastic adjustment system at the ankle that adapts to your movement for a snug and comfortable fit, without restrictions. Keeps the pants in place while you climb.
Dual-fabric pattern for maximum performance
Hybrid construction that combines flexible black Japanese denim in key movement areas for total freedom, with 11oz grey denim in structural zones for shape and durability. Stretch where you need it, durability where it matters.

Details by color: Jade
210gsm canvas, designed for durability and resistance. Ideal for colder climates, indoor climbing gyms, or rough outdoor terrain. Still flexible, but more robust where it matters.
Details by color: Onyx
Japanese denim, ideal for warm weather or extended daytime wear. Slightly more breathable, with a softer feel from the very first climb.
Details by color - Rose Quart
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.
