About Advance Progress 4
Reversible harness-rucksack system, so it flips inside out into a 75 to 95 L pack for the hike up. The inflatable protector covers a large area right up to the lumbar and stays light and compact once packed. Split leg pads keep you precise in thermals, and the reworked back support holds up on long flights. EN and NfL certified to 120 kg. Harness runs 3.30 kg in S up to 3.65 kg in L, or 2.66 to 2.99 kg without the rucksack part. Three sizes cover pilots from 155 to 202 cm.
