Bubble Unisex Anti-UV Lightweight Jacket

The ventilation openings are located on the back area, where heat tends to build up most easily when wearing a backpack in summer. The vents use a hidden opening design to help release trapped heat and moisture effectively while maintaining the jacket’s sun-protection performance.

It uses yarn-level sun protection, meaning the UV-blocking elements are woven directly into the yarn rather than added as a surface coating. Because of this, repeated washing, friction, and sweating will not easily reduce the sun-protection effect, making it long-lasting and durable. Many regular sun-protective shirts rely on coating-based protection, which may lose effectiveness after several washes.

The reflective strips are placed on visible areas such as the front chest, back, and arms. When illuminated by car headlights or streetlights, they create a high-brightness reflective effect, making you easier for drivers to notice from a distance. This design is especially useful for night running, night cycling, and evening commuting in low-light environments, helping improve overall safety.

UPF 100+ means the fabric blocks more than 99% of UV rays. For regular city commuting, UPF 40+ is usually sufficient. The advantage of UPF 100+ is mainly seen in extreme outdoor conditions or for users who want a higher level of sun protection, offering more comprehensive coverage against UV exposure.

Yes, the cuffs use an elastic binding design with a certain amount of stretch. The elastic cuffs help keep the sleeve opening lightly fitted around the hand while maintaining basic comfort and coverage.

The top of the zipper has an anti-pinch design, and the zipper pull is covered by a fabric guard. When the zipper is fully closed, it should not directly rub against the skin or cause discomfort around the chin.
