I loved the original Hex Nano Watch Band. I used it every day at work wandering around the office and the only drawback that I could see is that I didn’t have access to the pin connector. Well when Hex came out with the Sport band they solved that problem. With a slightly slimmer band and ventilated design the Sport band has an opening for the standard Apple connection that allows you to connect your charger, FM Modulator, or other accessories. I have been using mine with the Nike + system when I go running and its been really nice to have it all in one little package. Routing the headphone cables up my sleeve I don’t have to worry about tangles and I can set up my workout and be on my way with a minimum of bulk which was my big problem with a lot of the arm bands and other work out accessories. Other than that port this is still the same basic design. The Nano pops in and out very easily and I think the biggest improvement is the smaller band. The original Hex band seemed a tad bulky at times, but I usually wear thin watches instead of the trendy giant ones the size of dinner plates. The band is $30 from shophex.com and comes in 5 different colors. If you like the added functionality of having your Nano serve as your watch and want to use it with Nike + or any other accessories I highly recommend it.
