Turn your Jetboil Personal Cooking System into a French press and sip your favorite coffee in the backcountry with this accessory. The minimal weight is a small price to pay to enjoy your favorite bean rather than instant coffee. It works just like a French press in your Jetboil cup. The kit includes the basket, rod, and knob and it stows inside Jetboil cup, so it won't take up any space in your pack!
