So you wanna buy some gear? Maybe sell some gear? New? 2nd hand? It's for skiing, climbing, hiking, kayaking, camping, scuba-diving, marathoning, biking, mbt, nude trekking and so on? Well before you despair of the poor response rate from your local post it notes at the gym, KOTR or such, grab a Korean buddy and check out
www.okoutdoor.com even though it is only available in Korean, you can see there is a wealth of info and products. Some great deals too.
