The RK30 is a roll-top design. It is made from the same fabrics as our AK range, and is fully waterproof. It is an exceptionally tough pack that is ideal for technical routes that involve hauling and necessary physical abuse, but is equally at home for activities in very wet conditions. The RK30 has been updated for 2020, and features a new removable front/side compression system.

Only red is currently available.
