Really pleased with the vest. Easy to adjust, sits nicely on the body and feels good value for the price compared to others I looked at.
only used it a few times but no issues. fast delivery, fits well and doesnt bounce. happy with it at this stage.
Very happy with my purchase. Good quality, fair price and arrived quickly. I’ve already recommended it to a friend.
used this on a few faster sessions and it didnt move at all. straps stayed tight and no rubbing.
I’ve tried more expensive hydration vests and honestly this is just as good. Lightweight, practical and well designed.
holds water and bits i need and doesnt annoy me while running.
I was worried it might feel loose but once adjusted it stays in place. Very comfortable on longer runs and breathable too.
ordered monday and had it wednesday. vest fits good and feels solid. flask is a nice bonus.
Using this during marathon prep and it’s been spot on. Easy access to gels, phone fits well and no chafing at all.
Ordered the wrong size by mistake and got sorted very quickly. Really easy to deal with and the vest itself is very comfortable.
I looked at a few similar vests and this was by far the best value. Does everything I need without paying big-brand prices.
Great fit and very comfortable even on faster runs. Doesn’t move at all when picking up the pace. Feels well balanced once adjusted.
Not much to say really. fits fine, comfortable and doesn't annoy me while running which is all i wanted.
Bought this for my longer runs and it’s been great so far. plenty of room for phone and keys. Just made another purchase for my sister :)
