Review on 🗑️ Maxsa 21520 Waterproof Seatback Trash Can: Secure Velcro Closure, Stylish Black Design by Chris Hayes

That's a good idea. The bag fits easily behind the seat and is easily accessible. When you're driving, just pull them back and drop them. It has an open fit and is held in place by an adjustable strap that wraps around the headrest. Closing is easy, it has a velcro closure at the top with a fold over closure. Not entirely odor proof, but mostly if you regularly throw out something really smelly. The bag is hard-wearing, absolutely moisture-wicking and waterproof. I'd just say if you leave it hanging from the seat back, thieves might think there's something to steal. So I would put my bag if not in the car but in the area where cars are broken. I live in San Francisco and that's a problem here, so when I got out of the car I took my bag off and put it on the ground so it wasn't as visible. It's a good idea, works well, is a pleasure to buy and keep clean!
