The MSR Adjustable Poles are light, adjustable, collapsible poles that add standing-room height to any MSR wing or tarp shelter. Spring loaded locking mechanism allows campers to change length for optimal height. Available in three sizes, the poles have a collapsible, aircraft-grade aluminum shaft that’s light and easy to pack. The 4-foot pole adjusts from 47-55 inches for smaller shelters, while the 5-foot pole adjusts from 55-66 inches. The 8-foot pole adjusts from 82-102 inches to fit taller shelters.
