All right

"Good quality, lightweight"

Gurwan P. (5/5)

Trail Bag

"For my first real trail hydration pack, I'm completely satisfied. The tightening system allows for a precise fit. It has plenty of handy pockets. I tested it in the rain, and my gear stayed well protected. One minor drawback: the zippers seem flimsy; instructions on how to attach the quiver would be welcome."

Great look, lightweight, comfortable, and functional.

Q&A

Hello, I already have a 3L Kinétik hydration vest in size 3 that fits me pretty well. Should I get the same size for an rk15 But I'm a 30-year-old man who is 1m81 tall, weighs 81 kg, and has a chest circumference of 97 cm.
Hello, Thank you for your interest. Size 3 should also work. Please feel free to refer directly to our size guide on the product page. Have a great day!
