Says latex in the products description. If its natural latex from the rubber tree it will last longer if its synthetic it wont last as long.
You will get about 10 years out of a heavy duty latex mattress but In general adult catsuits will last for around 3-4 years.
Adult latex clothing is much thicker than the 1/6 suit which is very thin and a similar thickness to that of a balloon, as he showed on Jazzincs video when he stretched it in his hand, so for myself I cannot justify that cost.
Joost said in the recent stream the real suit isn’t latex, and they aren’t making it from real latex either. It’s a 4-way stretch fabric material similar to the custom run Sean did before so it should hold up well. We can see the fabric stitching in the closeup shots. Not sure why the description says latex though since Joost talked about it before that they aren’t using real latex which has a terrible lifespan.
