Well, for all the times I've said try NOT to look military, I admit that my BOB is in woodland camo under all the pouches, and my ditch kit is mounted on a chest harness. *shrugs* Wear it with khaki or grey utilities, work boots, a checked shirt and under a non military poncho and you should be fine. Particularly if you have a bright red or yellow compression bag for your sleeping bag.

If people ask, I tell them it a comfortable way to carry gear- front and back balance out. ANd when I'm just carrying the ditch kit, it gets put on backwards and worn as a lumbar pack. Never had a second glance from someone.
