SteelFan, what do you think of .300 Win Mag?

Also, do you have any experience with this bit of kit.

I feel like a mall ninja for wanting one but it looks nice.
DPM is the best camo for my area year round for both blending and breaking up the human shape, all or my kit is in DPM except for some nylon and a field jacket that is olive.
I wear the ripstop DPM Jacket Field regularly and I figure the arktis is a good upgrade, maybe something I can buy at the end of the summer if I have some money left over.
Of course shooting gear is probly a better idea, just wondering if you have used it.
