so I got a worn once for Halloween but otherwise brand new leafy suit off CL and it seems like the leaf material is noisy when you move I know there is no way you can move in this if a deer is close,, so wondering should I wash this a few times or maybe leave it in a bucket of water for a week to soften everything?  

any ideas?

I'd try washing, maybe with an unscented fabric softener..

Wear it! It will get softer over time.
Maybe put it in the dryer for several cycles and see if that helps.  

dryer worked well for me, put it in a few times,  Mike

I always wash a new leafy suit in Un scented detergent before using the first time and dry on low.  It'll make it soft and the more you wear it the more it'll break in.

thanks for the tips I will give it a shot.
