Bloc are your boulder-problem solving companions. With them you can reach higher footholds, execute awkward moves and bridge with ease. They’re tough, organic cotton bouldering shorts built for dynamic movement and all-day comfort at the crag. Tackle off-width cracks, powerful heel hooks and delicate layback arêtes from Font to Froggatt.

  • High stretch, organic cotton fabric for climbing comfort
  • A gusseted crotch for movement
  • Low-profile elastic waistband fits neatly under a harness
  • GOTS certified cotton uses less CO2 and less water to produce

Designer’s notes

“For Bloc we wanted to create shorts that are more flexible than you are and would never hold you back mid-climb. A diamond-shape gusseted crotch and a touch of spandex in the fabric both help to keep the limbs loose. The fabric also allowed a slimmer fit than standard so you can see where you’re placing your toes.

Climbing shorts need to be durable, especially if being subjected to rough Peak District grit. Cotton is a naturally hard-wearing material so was the obvious choice. We finished Bloc with a simple, low-profile elastic waistband that’s easy on and comfortable with a harness. Four pockets mean you don’t have to leave valuables hanging around.”

Ronnie, Clothing Design Manager

How It Is Made

Organic Cotton

These shorts are made from Global Organic Textile Standard certified organic cotton. Organic cotton farming produces significantly less CO₂, uses less water and eliminates the use of harmful pesticides. And it feels great!

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.

We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
