A downloop / frontloop / forward loop - is when the kite is looped "forward" in the travel direction through the air.
A backloop (uploop), also sometimes just called a loop - is when the kite is looped around "against" the travel direction.
Typically meaning, that when you pull the loop with your front hand according to the direction when you took off, it is a downloop / frontloop / forward loop.
And when using your back hand, it is a backloop or just a loop
Of course, when up high and you have no significant speed across the wind, it is the same whether you pull a front or backloop, but the terms are still fine as you WILL have had a direction of travel when you took off, so noone is in doubt what direction you mean
