The Base LT Down Zip Jacket is a lightweight and adaptable outer layer designed with versatility in mind. Made from durable nylon ripstop with a water-repellent finish, it provides reliable wind and down-proof protection. Filled with responsibly sourced down for warmth, its standout feature is detachable sleeves that allow it to convert into a short-sleeve silhouette. Functional details such as elastic cuffs, adjustable hem, and secure zip pockets make it a practical piece for both performance and everyday use.
