This amazing combination backpack / seat comes to us from Sweden where at an orienteering meet everyone has one. Carry all your o-gear and your food and drink to the arena, and have a place to sit and watch the race, to wait for your start, to use to when putting your shoes on, and to sit and gossip with your clubmates. It's the next greatest thing in orienteering in North America! The A Series backpacks have fewer bells and whistles than the 1030 or 1040 and are therefore a little cheaper, but they still have the seat, the raincover and the comfortable shoulder and waist straps. The A45 has a 45L pack.
