When choosing a sun-protective jacket, you can consider the following factors:
1. Material: The material of the sun protection clothing should be lightweight and breathable, so that one won't feel hot when wearing it. High-quality sun protection fabric can provide good sun protection effect while maintaining comfort.
2. Color: Dark-colored sun protection clothing offers better protection than light-colored ones because dark colors can more effectively absorb ultraviolet rays. For example, sun protection clothing in colors like deep red and navy blue usually has better sun protection effect than other colors.
3. Craftsmanship: When choosing sun protection clothing, pay attention to checking if the label indicates the national standard number and UPF value. The UPF value represents the sun protection ability of the sun protection clothing, and the higher the UPF value, the better the sun protection effect. At the same time, the UVA value is also an important indicator, representing the sun protection ability of the sun protection clothing against long-wave ultraviolet rays. Choose sun protection clothing with an UPF value greater than 40 and an UVA value less than 5%.
4. Comfort: The comfort of the sun protection clothing is also very important. Choose sun protection clothing that suits your body shape and skin type. During the fitting process, pay attention to checking whether the collar, cuffs, and hem of the sun protection clothing fit your body well, to avoid ultraviolet rays penetrating through these parts and reaching your skin.
5. Design and Style: Besides the above factors, the design and style of the sun protection clothing are also factors to consider when choosing. You can select the suitable style and color according to your own preferences and needs.
In conclusion, when choosing a sun-protective garment, one should take into account various factors such as material, color, craftsmanship, comfort, and design, in order to select a sun-protective garment that not only offers good protection but also is comfortable to wear.
