"Yfumble" Review by
Bought 1 for a gift and 1 for me. It is my second,just wanted another colour. The original one is still going strong.
"Fab...." Review by
I've been training for my first ever marathon and just hate wearing a running belt to carry gels and sweets. Can't stand being weighted down and the bumping around!! I bought one for each arm and can easily fit 2 gels in each, plus an ipod and car key. Even after 22+ miles, they do not rub. They are light, secure and hold their shape after being washed. Would definitely reccommend.
"More good points than bad" Review by
I have slim arms and the medium fits me nicely, is comfortable aware and carries my iPhone securely. That said, I use my phone to play a training app that needs to start as I do. It's fine to hit start and then slip the phone into a carrier but ironically, I fumble to do this with one hand and have to find someone else to put my phone in which takes a while! I'm developing a hand and teeth method though : )
"Good option" Review by
I wanted something to carry my iphone on long runs but hate the velcro style arm bands - I needed something lightweight and easy to use. This item is great - you can't mess with your phone once it is in but it felt secure and it's comfy to wear.
"Good for cash/keys" Review by
I bought the small one since I'm wee but it's too small to wear on upper arm comfortably even when empty. Would be useful to have a clearer size guide i.e arm circumference - now I've checked the manufacturer website they size by 'build' but I still wouldn't have expected my arms to be 'medium' particularly in a unisex product. Consequently although my iPhone fits into the pocket it is uncomfortable to wear and impractical on the forearm when listening to music. Great product however for house key and emergency cash! My other slight gripe is that I've only used it twice and already some stitching is coming undone....could have made life difficult had I not spotted it!!
"Great easy to use product" Review by
Simple arm band which can hold anything. I've used mine in cold and hot conditions, holding keys, change and my iPhone (all together). The band is strong enough to cope with the weight, doesn't lose shape and is very light - you hardly know you're wearing it.
