This size of rucksack is one of the most practical available. It will function as a cragsack, a daysack for hillwalking, a weekend bag for those short trips away and at pinch even longer trips. The Cuillin 35 Rucksack has a split main compartment with two large side pockets. The front has a zipped pocket for smaller easy access items. The lid has a zipped section and also a key clip. There is a rain cover in the base. The back system has breathable mesh on all body contact parts-very important in warmer weather.
