Harrier soft flasks & bladder are robust, faff free and essentially do not leak, they are exactly what I wanted!

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.

I'm delighted to say that they have won the Best Value award in the Wild Ginger Running poles test for their excellent features and low weight at a really fantastic price!

I am looking forward to using them on my next multi-day running adventure.

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!
