Harness and backpack in one
The Alpine is UP's new reversible harness, made for pilots for whom, say, a Nanga is just way over the top heavy and bulky. By building the harness into the paraglider backpack the designers have accomplished something of a Columbus' egg in that the main achilles heel of lightweight harnesses (passive safety) has been fixed without adding weight or bulk to the total package - even with a super lightweight kit you'd still need the backpack to carry it in, so why not put it to good use?
