Polymer gel muscles will be five times stronger than natural ones, so you could buy clothing that gives you superhuman strength.
They are too expensive to make today, but not in the future.
Imagine free-running and leaping between buildings like a superhero, and having built-in reactive armour to make you bulletproof too, with extra super-senses also built in.
A lot of that stuff is feasible, so exoskeletons might become very popular leisure and sports wear, as well as the obvious military and emergency service uses.
