Combining the best features from the already popular ‘R’ series of packs, joined together with the waterproof protection of the ‘US’ series drybags, the R30 comes ready for any weather conditions and situation. It straps on comfortably and securely with the Quadlock harness system, and features CNC buckle adjustments at the hips and a closed loop strap system at the top. A six-point compression system keeps items synched-in tight and two water resistant outer pockets allow quick access to your oft used items. The 30 liter main body is 100% waterproof and top-loads with a roll-top quick release closure system, providing 1890 cubic inches of storage. Highly reflective panels front and back increase nighttime visibility. Strap on extra waterproof capacity by attaching a US-5 (pg. 84 #9163) for 300 additional cubic inches of space, or over 600 cubic inches with a US-10 (pg. 85 #9065). (Not designed to carry the 3L Hydrapak.) 19.3"×11.8"×8.3".
