I've used totes for years, but the last few years, I've just used contractor grade garbage bags.
I usually leave clothes stored in totes, but then, in the morning while I shower, I treat what I need for a days hunt. I'll give the bag a shake or two while the unit is running to distribute the O3.
I see no reason to store treated clothes...who knows if they can become contaminated somehow. We are dealing with critters which we have no concept of their olfactory limits. May as well just treat what you need just before the hunt.
I also like garbage bags for tossing clothes into after the hunt. I don't want to contaminate a tub by throwing used clothes in it. Plastic does absorb and hold odors. My wife has one dedicated Tupperware container for storing onion. Every other container that has had onion in, smells like onion for a long time. I refuse to throw contaminated clothes into a tub, unless the tub is dedicated for that purpose only.
Garbage bags take up less space in the vehicle, too.They will stuff into places where a tub can't.
Another thing I like about garbage bags is I use them for seat covers on the day of the hunt.
Even though I treat my truck with O3, I still don't want to sit on cloth seats after I've showered. 52 weeks a year, my truck seats have me sitting and contaminating them. Think about it...seats are padded with foam underneath. Every time we sit on a seat it billows the contaminated air. I have to believe that those odors cross-contaminate my base layer when I drive to the hunt. I dislike standing buck naked in freezing wind to dress so I do usually wear 1 base layer when I drive to the hunt and finish dressing at the parking spot. I don't want that base layer touching my truck seat so I slip a bag over the back and sit on another.
Garbage bags...cheap, they work well for multiple purposes, and you can use them for their intended purpose when the season is over. Just don't get the perfumed ones.
