Lyle & Scott Heat Reactive Shell Jacket - Brown

Heat reactive technology means the fabric of the jacket contains special pigments that change color or tone when exposed to different temperatures. This creates a subtle visual effect as you move between warm and cool environments.

As a 'shell jacket', it offers good resistance against light rain and wind, providing protection in mild weather conditions. However, it is generally not fully waterproof and may not keep you dry in heavy or prolonged downpours.

Always check the care label inside the jacket. Generally, it's recommended to machine wash cold on a gentle cycle, use a mild detergent, and never tumble dry or iron the jacket to protect its heat-reactive properties.

The jacket is lightweight and designed for layering. For colder winter weather, it's best worn as part of a layered system over warmer garments like sweaters or fleeces, rather than as a primary cold-weather jacket.

It features a looser, boxy fit. This design is intentional to provide comfort and allow for easy layering over other clothing items, giving it a modern and relaxed silhouette.

Under normal use and proper care, the heat-reactive effect should remain dynamic. However, exposure to extreme heat (e.g., from hot washes, tumble drying, or direct ironing) can potentially damage the reactive pigments and lead to irreversible changes or dulling of the effect.

Ensure there is a noticeable temperature difference between your body/surroundings and the jacket's surface. The effect is subtle, not an instant color change. Test by moving from a cool room to a warmer one, or vice-versa.

The jacket is designed with a looser, boxy fit specifically for comfort and layering. This is an intentional design choice. If you prefer a more snug fit, consider trying a size down, though this might impact layering ability.

Always follow the care label instructions precisely, especially regarding water temperature and drying methods. High heat (from washing, drying, or ironing) can damage the heat-reactive material. If damage occurs, it may be irreversible.

Apply a small amount of zipper lubricant (like zipper wax or a graphite pencil) to the zipper teeth. Gently work the zipper up and down to distribute the lubricant. Avoid forcing the zipper, as this can cause damage.
