Smartphone running armband (Kalenji) black

Very comfortable & safe when running with it strapped on my upper left arm . It only gets abit wet after ending jogging due to perspiration soaked in , so need to dry it under sun after usage .

Hello Manoranjithan,

Thank you for taking the time to leave a feedback on our Smartphone Running Armband (Kalenji) black. It is with constant feedback from customers like yourself that we can work and improve our products.

Just as you have mentioned, it is easy to strap on and use thanks to adjustable velcro. Moreover, the Smartphone Running Armband (Kalenji) black has a zip closure so moisture stays outside of the pocket.

We thank you for this feedback and do leave us more review of our other products so we may continue to improve.

Your happy runner,

Weihoe | Running Sports Leader

Hello Prince, 

I am extremely sorry to hear about your experience with the Running Armband. 

I would request you to help me know your needs, then only I can help you out with the solution. Ideally, these are meant to accommodate phone sizes with 8 cm X 14.3 cm, for example, iPhone 8, 7, 6 and GALAXY S6, S5, S4, etc. 

So, I'll be looking forward to hearing from you. And you can visit the nearest Decathlon store, as over there our sales advisors will be happy to assist you.

Hello Kapil,

I am sorry to hear about your bad experience with Running Armband. I understand your concern and that's why I am here to help you out. 

This armband can accommodate phone with the same size as iPhone 8, 7, 6 and GALAXY S6, S5, S4, etc. (Pocket size 8 cm X 14.3 cm). If your arm is small or if you carry the armband on your wrist you can tuck any surplus strap into the loop designed for this purpose. I would request you to please visit your nearest Decathlon store, as over there our sales advisors can help you out in demonstrating how to use it. In case if still, you feel it is not helping you then you can ask for a refund. 

I'll stay available in case of any concerns. 

Good Armband

Qualitywise it's worth for money.. Fits well on my arm. Only problem is my phone doesn't fit completely in the armband as I cannot seal the pouch which increases risk of falling phone.

Good product

Reasonably good quality

Kalenji Armband

good Product, value for money

icon-circle-checkmark verified purchase

The armband may fit the arm but the size limit if the phone is too small most modern or new phones will not fit inside fully and it cannot be closed. Due to which the chances of the phone falling out is very high

Just works

Great value, easy to use and comfortable

Armband disappointment

My phone doesn't fit in the smartphone armband as I initially thought

Good but not absolutely great

Nothing wrong with this armband but would have preferred a more user friendly experience with Velcro armband and a different fastening for the arm pod section.

Mobile arm band

Great product but overpriced, secondly can have a hole or eye opening for audio jack insertion.
