Recently I have been trying to lose weight as I have gained so much and when I go for my walks I need to take my phone, keys, I pod, camera but I never have enough pockets to put them and end up carrying some things as my pockets are only so big. I found this great company called ARMPOCKET. They offer a variety of different pockets for such the situation in a wide variety of colors. I got the purple i-10 which is 5” and keeps valuables safe and dry, fits smartphones, has ear bud access and reflective piping. It fits around your arm and strap comes in Medium and Large sizes what I like about this is all my stuff fits, the strap is water resistant, touch thru window for touch screen phones, Dual zippers, made with No-Slip Memory Foam so it stays in place. This can be used to take anywhere you do not want a wallet or purse in my opinion not just working out, everyday use. I know when I go to events I do not want to carry a huge purse around. The others they have are i-15,i-20, i-25,i-30, i-35 and Nighthawk visit www.armpocket.com/ to learn more.
