The Zpacks Carbon Fiber Tent Poles are purpose-built shelter poles meant to support tarps and trekking-pole-style shelters, not to replace walking poles for hiking. The 52-inch (132 cm) variant weighs just 80 g, roughly a fifth the weight of a typical pair of trekking poles, since a shelter pole carries no hiker's body weight and needs no length-adjustment lock.
Construction is fixed-length, with sections joined by internal shock cord the way conventional tent poles are, so the segments self-align when unfolded. An 11 mm shaft diameter gives enough stiffness to hold up a tarp in light wind without adding unnecessary weight. They are sold individually, so you need to order the right number of poles to match a given shelter's design. This is a clear ultralight-category item, aimed at people whose shelter is already designed around pole support rather than trekking poles and who are counting every gram.
