RK12 — 12-liter hydration vest for trail running

The RK12 is a 12-liter hydration pack designed for long-distance runs and demanding ultra-trails. Weighing a record-breaking 140 g, it ranks as the world’s lightest pack in its category.

Each pocket has been strategically positioned to offer optimal organization, allowing you to store your gear by category and priority of access, without wasting time or sacrificing comfort.

Its new exclusive Thintex80 material completely eliminates the bouncing often felt with traditional trail packs, ensuring maximum stability even during high-intensity activity.

A true second skin

"Actually, the pack stays so still that you could almost forget you're wearing it while running. It's very comfortable. One downside is the lack of a mounting system in the back pocket for a hydration bladder, which would be great for long runs. Other than that, it's flawless."

— Fabrice V. (4/5)

Ultra-lightweight—you'll forget you're even wearing it

"First test yesterday—to be honest, I was worried about the fit when I tried it on... even though I’d followed the sizing guide! A 1-liter water bladder, my phone, a few energy bars, and off we went for 23 km... a few more adjustments during the first kilometer... and PERFECT!"

Great bag, lightweight

"A great bag—lightweight and impressive for its small size and large capacity. Highly recommended. I used it at the Ultra Marin and it was perfect. Thanks to Kinetik for their advice at their booth."
