The Ether Boys' Hoody is an ultra-lightweight, breathable windbreaker finished with a durable water-repellent coating, making it a great choice for moderate aerobic activity in mild climates. This jacket's interior also remains dry and comfortable while he's on the move, thanks to its DriClime bi-component lining that efficiently pulls moisture away from his skin and into the air. The Ether also features an attached hood that rolls up when not in use, mesh underarm vents for temperature regulation, elastic cuffs for a secure, draft-free fit, and reflective trim to maintain visibility in low light. Your child's arms will retain full mobility through it all, thanks to the built-in Angel-Wing Movement.
