I'm not sure the brand of armband I have. I got it off ebay for $5. I was a little worried about it staying on since the band was neoprene so I just bought about a foot of 2in elastic and some extra velcro and MacGyver'ed it(thank you Home Ec for teaching me to sew). For those of you worried that the EVO is too big to run with...I'm only 5'2...it takes up most of my upper arm...but I'm sure you guys are probably much taller and have longer arms. I'm currently using a free app called RunStar. I'm sure there are better out there but this one has a good interface and nice big buttons...easy to use if while you're running. I'm not sure about it fitting into my jacket for ski season but...then I guess I'll just buy a new jacket!
