I just hang mine in the closet till next year. Shortly before archery season opens I get it all out and give it a wash in odor free non-uv brightner detergent and hang it out on the line for a few days. Then I'm confident it's odor free and ready to go hunting.

I put mine in a big sealed box. Then just before hunting season it will get a good washing to get any odors that may have crept in over the off season.
