Run Deep Mag
It was a tremendously positive experience using the Harrier Soft Flask. I was really confident about the quality of the flasks and was not surprised that cleaning and drying them was just as easy. They stayed open while drying so no water remained inside.
The Harrier soft flask is a great buy. Fantastic price for a well-made, robust and reliable soft flask that does exactly what it’s supposed to do: provide you with an efficient means of getting fluids down you while out enjoying your run. I now want them in every colour!
Wow, I really was impressed with all the kit we tested in the Harrier Ultra bundle. The Kinder 10ltr race vest ran so well over the 38 mile route I tested it on. I was carrying a lot of kit and water and the vest was super comfortable, with very little movement.
All in all I would highly recommend the Harrier kit, I personally think you'd struggle to find better trail running kit at this price point. It really is amazing value!
I’ve been using Harrier soft flasks (& bladder) for a few months now. Being robust, faff free and essentially do not leak, they are exactly what I wanted! Long runs are difficult enough without hydration system issues which I’ve had my fair share of.
It’s great to have flasks I trust especially when doing what I love most, fast packing in remote areas. Harrier have their priorities right. Great quality products with a fast and friendly service so you can focus on what it’s all about, enjoying the trails.
