First, how to choose a sunscreen?
Sun protection, the specific protection is ultraviolet light, more specific? UVA？ And then what? UVB？ [ 1]:
UVA: 95% of ultraviolet rays, with a long wavelength of 320nm-400nm, can reach the dermis and is mainly used for tanning and aging;
UVB: It accounts for 5% of ultraviolet rays, and the wavelength is between 290 nm and 320 nm, which is the chief culprit of sunburn.
If you want to avoid counterfeit sunscreen clothing perfectly, you must first look at the implementation standards, fabrics and sunscreen technology before buying.
1, see implementation standard.
According to the national standard GB/T 18830-2009 "Evaluation of Ultraviolet Resistance of Textiles" [2], only? UPF & gt； 40 and UVA transmittance

Figure 2
So in theory, the higher the UPF value, the better, but in real life, UPF 40+ can meet everyone's daily sun protection needs. If you have to be outdoors for a long time, choose? UPF 50+？ Yes
2. Look at this cloth
Fabric is also a point that can't be ignored when choosing sunscreen clothing. It is best to be light and breathable while having good sun protection. Think about it. If the clothes are sultry and heavy, they really look like torture in summer. If you can't wear it for a long time, the sunscreen effect will be greatly reduced.
Among the common fabrics at present, polyester (also called polyester fiber) and nylon are the most suitable for sun protection clothing, which have outstanding sun protection ability, air permeability and moisture absorption and perspiration.
So, you can buy only these two kinds of fabrics, or you can buy a mix of the two fabrics ~
Step 3 look at the sunscreen process
In addition to relying on the clothing fiber itself for sun protection, some brands will also add sunscreen to the sun protection clothing. What is commonly used at present? Three processes:
If you want long-term sun protection, just choose from the "raw yarn sun protection". Don't worry about how to tell, brands using this technology will definitely tell you, and even want to say it in your ear with a big speaker ~
Second, when to plant grass?
There are three kinds of recommended sun protection clothes, both basic and advanced, with a wide price range, so you can choose ~
1、? L 'Orsune "Mu Guang" Full Face Protection Sunscreen
Ohsunny is a brand specializing in sunscreen products in China, and this one is the basic model of "Muguang" series. Is it independently developed? Twilight yarn has the characteristics of durable sun protection, lightness and breathability, and the UPF value is 50+. Moreover, there are sun visors, face protection and hand protection, and short models are also convenient for riding. One piece is enough to meet our daily sun protection needs ~
2、? Looking for a long orange sunscreen.
Nightgown-style sunscreen looks a bit strange, but it is wonderful in an instant, and it is simply a good friend of lazy people in summer! I not only commute to work, but also go out to get express delivery and throw garbage. I also put one on my pajamas and went downstairs. Does it have UPF50+ and its length? 1 12cm can cover most of the lower body, eliminating the trouble of "applying body sunscreen". Moreover, it uses a two-way zipper, so we can adjust the size of the hem split by ourselves, and we don't have to worry about it waiting around our legs for a while, which will affect our walking.
3、? Zauo slim sunscreen clothing
If you think most sun protection clothes are loose and inconvenient to walk around, you can try this one of zauo. The version is slim, it is very docile to wear, and there are few wrinkles. Even the hem will not be loose, making people look tall and energetic as a whole, and they will not be sloppy. It also adopts the sun protection technology of raw yarn, with UPF value reaching 50+ and balanced sun protection? The cuffs are lengthened to protect the back of the hand from the sun, and the hat is deepened to protect the face more comprehensively.
4、? Kaileshi outdoor sunproof clothes
KAILAS is one of the world famous "all-climbing brands". The design of this sunscreen suit really takes all aspects into consideration for outdoor athletes. First of all, it almost prolongs the sun protection, and the UPF value is 100+. Secondly, it is breathable and quick-drying, and it is also very thin. The whole dress is only 130g, and its weight is similar to that of a mobile phone. It doesn't take up space in the bag.
5、? Banana cold noodles 502? Ultraviolet air
Students who care more about the coolness of sun protection clothes can try this one of Banana, which belongs to its famous "Cold Skin Series". It uses the original yarn sunscreen technology, UPF 50+, and also adds Movestech to bananas. Ultraviolet cool sunscreen technology, woven with cool particles and yarns, can accelerate the heat transfer between skin and clothes, so that we can wear it in summer. It can be stored as a small small backpack, and it is not only convenient but also beautiful to carry around when you don't want to wear it.
6、? Banana AL 1 16 sunscreen clothing
This one under the banana also uses the original yarn sunscreen process (UPF 50+), which is durable and cool to wear with the cool technology of AirLoop. It is fully protected. How long is it? 70cm, completely covering the whole upper body, and the brim is also coated with a layer of black glue, which has stronger sun protection ability.
Finally, let's make a summary. If you want to buy sunscreen, you can look at these three points:
It should be on the label, right? Three signs: the standard GB/T 18830-2009, UPF value, and the hint of weakening the protection effect under special circumstances.
This fabric is a blend of polyester and nylon or polyester.
It is best to choose raw yarn for sun protection.
In addition, I want to say that many clothing brands are now making clothes with sun protection function. The style is better, but the price has also increased accordingly. You can choose according to the prompt, first see if there is really a sunscreen function before you start!
