I have used the Boulder trousers ‘extensively’ not only for climbing but for after Mountain Runs and Mountain Biking. I like the material: Light, durable and dries quickly. I especially like the lightness. I am a fan of multi day lightweight backpacking , these will be perfect. I also like features such as the Velcro fly, easy to use even with gloves, avoids problems with zips and makes the pants even lighter.
