I've used the Peltier vest a few times, but I'm selling it because my job changed and I no longer need it. The safety shoes were a gift, and I'm selling them new because I don't need them ^_^ The vest is size L, and it's a good fit – not too tight or too loose – even for someone slim like me, and it has stretch ^_^ The safety shoes are 27 cm. Please consider them if you're interested ^_^
