I own several of the HR silicon sport straps now and they are all amazing! The quality, durability and asthetics are top-notch! These are some of the most comfortable straps I own! They don't make me break out into a rash when I sweat like polyurethane straps do. I would highly recommend these straps to anyone who is looking for a durable, lightweight, supper soft all-weather strap for any of their watches. I even have the blue/black version of this strap on one of my expensive Stuhrling Original Tourbillon Watches with a blue case/dial and it just added a level of style to the watch that I don't think it had even with it's expensive genuine crocodile leather strap! That is how amazing these straps are!
NOTE: these straps do NOT come with spring bars, those have to be purchased separately.
