Thanks for the tips people.
I wouldn't try garbage bags since they make noise and they are higly reflective. Also, from my point of view (a clor blind's point of view), clothes that are the same colors than trees are harder to see than white outfits. I guess this is because trees are standing in vertical position while 6ft tall snowmen arn't everywhere in the forest.
I'll try to grab some camo from walmart after I get a better gun (I'm still in walmart guns) and more airsoft money
.
I'll try to make a sweet outfit that looks like the WW2 german troops during the russian winter,
but in green
