i dunno age as in manufactured but ive had them from new, how long they were in the shop in packaging not a clue ... about 6 months by me, used about 4 times .. no rips or tears as I use the pull string things on them ... washed since i last used them and after every use.
If you buy them tonight i can post them with the headband all together ide do the evil top with it for 8 instead of 10 if you take the whole set. so 28 and you already have the head band
