I'd like a bit of variety in my airsoft clothing choices.
M81 is bae, A-Tacs FG works great in my area (along with RG) but a more "civilian" looking kit wouldn't be bad to have. Maybe with a ranger green shirt thrown in.
I wear my bike jeans (Rokker Revolutions), which have concealed D3O pads in the knees and hips and are also waterproof. Highly recommended, if a bit pricey.
