I'd like to put it on the balcony of my apartment and do muay thai work out there through the year and not have to worry about rain/snow messing it up.
When u leave it hanging the filling eventually packs down inside the bottom and makes the bag hard as a rock. Thats how i fractured my hand 10 yrs ago. Never took bag down at home one day goin at it hard for five min straight threw an uppercut style gut shot at the bag and it was like hitting concrete and crunch.
Bags like the century wavemaster have a base you fill with water or sand then an adjustable top. They're pretty stable when filled and you can remove the bag and store inside when not in use
