Great kit
Used for 2 to 8 weeks
I've tried various ways of carrying kit on long runs but this is by far the best , it would be nice to have at least one zip close pocket for security, but it's still a great load carrying system.
good for assisted race or road marathons
Used for 2 to 8 weeks
feel great as it hugs around your body. however, the lack of a hook or velcro for bladder on the back means your hydration is limited to soft flask in front. if they can add another fastener to the front pouch, will be great and add more secure to water flask from dropping out
Too big!
Used for 2 to 8 weeks
The capacity of this gilet suits me well, to carry water and gels etc on runs up to half marathon distance. However, on its smallest setting it’s too big for me, moves around, so it’s not comfortable, and I’ve ended up with chafed skin. When I tried it on, it didn’t feel too bad. I’m a petite size 8-10, but not tiny, tiny, maybe 54kg. Disappointing, as I’ll now have to spend more money buying a replacement.
Response of the brand
Hi Linda,
Thanks for your feedback on our 5L gillet for Trail Running. Just wanted to let you know we have 2 different sizes on this model (S/XS and M/L), if you have bought the M/L we can swap it for the smaller one, that might fit you better. Otherwise feel free to pop in your local store and speak to a member of the Running Team, and they will show you the other Trail Running Backpack we have, in case you would like to exchange it for a better fit.

Finally found my trail running vest!!
Used for 1 week or less
Had been looking around for a trail running vest for sometime. The two factor that had been stopping me is either the weight or price. Finally found this vest. Value for money. Try it out the yesterday with two 500ml bottles. It was bouncing at first but with a bit of adjustment, the bouncing stop. So much space to keep stuff I need during my trail run.

Hi Justin!

It's a pleasure that you are satisfied with this affordable trail running vest. Regarding the 500ml bottle, we have another alternative that you can use, which is our new 500ml soft flask. It is light and fits the trail vest perfectly. If you are interested, you can find this online with the model number 8487344, or you can simply come down to any of the Decathlon stores and we will be more than happy to assist you. Hope to see you around and have a good week! :-)

Brilliant, light weight, easy to use, good size pockets,great cheap price, amazing. Who needs a top name bag ,you only run with it the same.
Quite surprised
Used for 1 week or less
I happened upon this vest by accident and read as much as I could online with regards to quality and reviews. The previous model was well reviewed, nothing for the new model. Bought it on Sunday and went straight out for a 21km trail run on the South Downs Way.
I’ve been tempted to fork out for a good quality Ultimate Direction or Salomon hydration vest for a while. Fortunately I found this one. Solid as a rock. No movement, no chaffing. The quality looks surprisingly good for the price. The design is good. The colors are pretty hideous in my opinion, but at the end of the day I want something that fits well and will last. Still to be seen how long it lasts but for now I am happy and I will buy a couple to take home to my running mates in South Africa.
This product surpassed my expectations
