Updated to be even lighter, the redesigned Nano™ Vest is the preferred choice of Trail and Ultra runners looking for a minimal run vest. Updates include a lighter more minimal dual sternum strap attachment system that has integrated reflectivity, a removable safety whistle and a new 3D Micro Mesh that is lighter and more breathable. The new Nano offers a pack-only weight of less than 140-grams and includes two best-in-class 500 ml Quick Stow™ flasks. The updated 3D Micro Mesh enhances air flow and breathability while still offering great cushioning for added comfort and it comes in multiple sizes to ensure a personalized fit. It maintains the same streamlined gear organization you love, including a secure phone pocket, several stretch overflow pockets and it's signature trekking pole carry for accessing poles while running.
