Wonderful trail kit. My selfie Xmas present this year was a Harrier Kinder 10L running vest and two 0.5L soft hydration bottles. The longest run with this set-up so far was a 16mile/2700ft mini-epic on the southwest coast path from Penzance to Lands End in winter wet conditions. The pack held two 5L dry bags with an emergency kit and clothes - with plenty of room in the accessible pockets (still discovering all these) for snacks etc. Great fit, no chafing, and nothing too fiddly for cold fingers. The manufacturing quality looks great. Highly recommended. (Photo shows the kit still looking great at Lands End. Sadly the attached human was a wreck by this stage.)
