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.
It was a tremendously positive experience using the Harrier Soft Flask. By now 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.
In short, the Harrier soft flask is a great buy. £10 is a 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!

Top bit of kit, I wasn’t expecting much due to it being a new product to the market putting itself up against industry leaders like Salomon, Ultimate Direction etc. and I must say it’s matched them in every way possible 👍 Quality and value for money 10/10.
If I had any thing I’d like to see improve it would be wider shoulders on the filler neck but that is minor. I’m expecting big things from this manufacturer.

"Used the soft flasks for a twenty eight mile run. Couldn't recommend them highly enough, easy to fill at check points, don't leak and aren't as heavy as more expensive brands." Rosie
Mix and match

Straws are available as short tops or long straws. If you choose long straws, we will also include a short top for you to change as needed.
