Initially I was really impressed with the vest. I opted for the waterproof version as am in an area that experiences lots of rain.
Firstly the positives; the fit is great. It holds everything that I want it to, IPhone, Keys, AirPods, gels and the larger water bladder (although as others have said the bladder is slightly awkward to use as there is nothing to hold the straw and wrapping it round the strap rubbed against me and caused a blister and it is too long to hang free.)
Now the negatives; It isn’t waterproof in that the colour, when wet, bleeds out of the vest all over EVERYTHING! It dyed my skin, my clothing, my AirPod case, and the water bladder, all of which were brand new. And the dye does not budge.
I contacted EOS who replaced the vest immediately, but I had to go back and forth a little for a new water bladder. They stated the use wasn’t affected, but this item was brand new and stained by another of their faulty products, so eventually they replaced.
I wore the replacement vest on another wet run and once again, exactly the same issue., only this time my charity t shirt was wrecked which was really disappointing.
I put both vests in the wash to try and rid them of any excess dye and the prong to the front washed off entirely.
It’s a shame as I like everything about these vests and have trialled many options over the last couple of years, but this is quite a heavy design flaw that needs to be rectified.
To add, the pocket was also not entirely waterproof, with my belongings slightly damp inside. Probably fine with light rain but did not hold up well against the heavy rains we experience in the UK.

Comfy vest and the blue is waterproof. Only downside is the 500ml water bottle - doesn’t quite fit into the back pocket, I can’t figure it out!!

Thanks to this, I can run in the rain. Music in my ears and my phone kept dry on Spotify..So comfortable. Much better than wearing phone on my arm as I have done in the past

It’s is so handy and convenient

I love my pink EOS vest, but just heard about rainguard, and here in Mayo, as you know we get the odd shower! But need the pink version!
Thank you for you time
