Note that the top cover does have a small strip of double sided tape so that the cover stays on lid. Credevo fosse un difetto più unico che raro (sono MOLTO sfortunato con i mouse) invece riscontro lo stesso identico problema anche nel secondo esemplare appena acquistato su Amazon. You can do push-ups, dips, leg raises, and different variations of pull ups with it. I like it for me, however. I dont like a fleece that sits on my hip! I would say if you wear a nine or up get the large. I use these for swimming. My daughters and I have air pod knock off headphones and noticed that the fit wasnt great. I use it with my full face motorcycle helmet and I find the cord sliding to one side or the other. Well well made and sturdy, holds up my daughters mountain bike with ease, freeing up valuable space in our garage.
