I hesitated buying this as it felt like quite a big investment. However, after trying (and returning) two other brands I took the plunge and bought the pinnacle 12L based on the reviews specifically for women running long distances.
As soon as it arrived I loved how soft it felt, and the water system seemed really clever, not at all stiff and crinkly.
So far I’ve used it twice, the longest run being 30km. I had no issues at all, no soreness and it had plenty of storage options for my drinks and snacks and phone. At one point I took it off to get the food out, and I was really pleased with how easy it was to get on and off with no problems, not at all fiddly.
I have the grey coloured one, and I like the fact it makes me more visible on the roads as a lot of my running clothes are black.
Definitely worth the investment, the comfort and quality is beyond any other brands I’ve seen, and I’m looking forward to many many more miles with it supporting me.
