The Arma Lite 1/2 Zip is a lightweight technical half-zip jacket designed for those who spend long hours in the field — dealing with fast movement, changing temperatures, and conditions where weight and bulk matter. Its anatomical cut makes it well suited to dynamic shooting, hunting, and professional use during high-output activity.
The 95% polyester and 5% spandex construction balances two often competing demands: the polyester base keeps the fabric's shape and wicks moisture away, while the spandex content provides a freedom of movement that a rigid fabric simply cannot match. This combination is particularly useful in shooting positions — standing, kneeling, prone — where the jacket must not restrict the shoulders or pull under the arms. The construction is not waterproof: the fabric is designed to handle perspiration and physical exertion, not heavy rain.
The front half-zip lets you adjust ventilation on the move without removing the garment: open it when the pace picks up, close it when you stop and the temperature drops. Worn as a mid-layer over a technical base layer, or on its own during transitional seasons, it adapts well to the shifting conditions of a day in the field. The anatomical fit follows the measurements in the size chart and accounts for chest, waist, and hip circumferences suited to those carrying equipment.
Key features
- The polyester-spandex blend delivers freedom of movement in shooting positions without the fabric losing its shape over time.
- The front half-zip allows quick ventilation adjustment during activity without taking the jacket off.
- The anatomical cut is designed for use with equipment: no binding under the arms, no restriction of shoulder rotation.
- The technical fabric works as a mid-layer in a layering system or on its own in mild conditions.
- Available in six sizes from XS to 3XL, with a detailed size chart covering chest, waist, hips, and sleeve length.
