What owners are telling us.
Buy this as a lightweight, packable shell for hiking, travel, and fast-moving days in wind and intermittent rain. It generally keeps wearers dry and vents well, but prolonged, demanding wet weather produced one notable failure. Fit is inconsistent, with reports of tight layering space, extra room, and long sleeves. It is not the prudent choice for bushwhacking, sharp terrain, regular helmet use, or anyone needing substantial insulation and robust hardware.
