What kind of equipment should spectators wear to watch the Winter Olympics? What standards do you focus on when buying cold and warm equipment? The Beijing News reporter interviewed industry experts, professional equipment evaluation and brand owners, and asked them to provide consumers with some reference.

Snow sports are recommended to wear a knee-down coat
The ice and snow events of the Winter Olympics are held in different environments, and consumers need to determine the type of clothing according to different environments, temperatures and weather conditions.
“Considering that the ice event is held indoors and the temperature is relatively high, you can wear a long down jacket and a sweater, which is not much different from daily travel. However, like Chongli and Yanqing competition areas where snow sports are held, the temperature will reach or fall below minus 20 °C, from the perspective of watching the competition, mainly static warmth, which puts forward higher requirements for equipment. Outdoor gear media man Spur said.
Spurs recommends that viewers of snow sports should use a three-layer dressing method, that is, the outer layer is a knee-high down coat, the middle layer is fleece or thin cotton clothing, and the innermost layer is fast-drying sweat-wicking underwear.
Choosing merino wool with a high or half turtleneck for underwear is the best solution. Infographic
When choosing quick-drying sweat-wicking underwear, consumers are advised to buy warm sweat-wicking products. In terms of selection criteria, merino wool with a high or semi-high neck is the best. Merino products are generally marked with indicators: g/㎡, representing the weight of merino wool per square meter, divided into 150g, 260g, 300g, 320g and 380g five grades, generally 260g/㎡ products can be used as middleweight winter underwear, 320g/㎡ and 380g/㎡ underwear in cold environments. Such product signage will indicate the use environment, and choose the one suitable for winter. In addition, you can also choose chemical fiber materials, but you must avoid choosing ordinary cotton.
The middle layer is a thermal insulation layer, and static insulation mainly chooses three categories: fleece, cotton clothing or down. The fleece breathability is better, the warmth effect is general, you need to choose a little thicker. Cotton clothing is divided into two categories: the middle layer and the outer cotton clothing, and the middle layer is generally selected; The down is selected as a light and thin type, and the filling amount of the light and thin down jacket selected in early winter is 40~90 grams.
The outermost down jacket, when choosing, pay attention to the three indicators of fluffiness, down content and filling. Spurs recommends choosing products with more than 200 grams of pile and a one-piece hat, the fabric is mainly windproof and waterproof.
Zhu Wei, director of the Information Department of the China Down Industry Association, introduced that the higher the fluffiness of the down jacket, the better the warmth. The fluffiness of down generally starts at 12.5 cm, 16 cm is better, 20 cm is very good, and the international standard fluffiness values marked by some down jackets are 500, 650, 800 respectively. In addition, under the premise of the same fluffiness, the higher the filling, the better the warmth. The general thickness of the short down jacket is about 130 grams, the medium thickness is about 180 grams, and the down jacket suitable for outdoor wear in the north should be at least 180 grams or more.

Due to the different site temperatures of different projects, Bosideng brand sales staff suggest that consumers can choose lightweight temperature-locked products under the condition of 5°C/20°C, with a fluffiness of 600+, a lint content of 90%, and a filling capacity of 130g-150g. Under the condition of -15°C/10°C, choose medium and thick warm products, long products fluffiness 600+, lint content 90%, filling capacity 200g-300g. If under the condition of -30 °C/-10 °C, choose thickened and cold protection products, the fluffiness is 600+/800+, the lint content is 90%, and the filling amount is more than 200g.
Pants
The outermost layer must take into account the windproof, waterproof and breathable function
“Compared to the top, because the legs move relatively more, you can choose pants that are slightly thinner than the top.” Spurs suggests that the best pants matching is divided into three layers, the inner layer of sweat-wicking underwear, the middle is warm fleece or cotton pants, the outermost layer should pay special attention to windproof, waterproof and breathable functions, of course, the middle layer can also be integrated with the outer layer.
The purchase of the inner layer of sweat-wicking underwear and the middle layer can refer to the indicators of top-related products, and consumers can directly choose the whole set of products to buy. When choosing the outermost product, be sure to take into account the functions of windproof, waterproof and breathable.

It is understood that when the air penetration rate of the product fabric is 5l/㎡/min (the air value per minute passing through the fabric per square meter) or lower, the air permeability exceeds 5000g/㎡/24HR (one gram of water vapor per square meter per day), and the waterproof index is 10000mmH₂O (millimeter water column pressure) The product can achieve the function of windproof, breathable and waterproof.
Many products do not label detailed data indicators on the signage, and generally mark the waterproof fabric of the product. According to the advice of professionals of the China National Garment Association, ordinary consumers can pay attention to some fabrics with relatively high windproof and waterproof indicators when purchasing products. At present, the waterproof fabric with a domestic market share of about 70% is GORE-TEX, which is also a relatively high-priced product. According to KOLON SPORT’s salesman, its GORE-TEX fabric pants cost more than 1,000 yuan.
In addition, the professional suggested that consumers can also choose fabrics such as eVent, Neoshell and SympaTex, which are relatively few on the market but more cost-effective.
Spurs said that if consumers do not know much about data standards such as windproof and waterproof, they can also choose products with the word GORE-TEX or WINDSTPPER on the sign, which can fully achieve the effect of windproof and waterproof under severe cold conditions.

In addition to keeping warm and sweat-absorbing, the waterproof function cannot be ignored
Many consumers are accustomed to wearing single boots, which is not suitable for long-term standing in a -20°C environment, and the boots matched by spectators should pay attention to both warmth and waterproof.
In terms of waterproofing, depending on the way the shoes are waterproof, consumers can choose GORE-TEX material, full leather material or rubber boots. But no matter which waterproof material you choose, you must have enough filling. It is understood that 3M’s Primaloft (artificial cotton) and Thinsulate (Nasselli) are currently the most used synthetic materials filled between the boot lining and the shell.
According to the warmth index, light to medium weight boots have 200g/400g filling, while heavy cold weather boots have much more padding. There are brands that offer comfort or temperature ratings to their winter boots. For example, some ski boot labels will show a rating of -4°C or lower, in addition to the product’s own technology and material applications, consumers should choose the standard of weight of the filler and the fabric.
In addition to choosing the right shoes, consumers also need to choose warm socks for the Winter Olympics.
The choice of socks should consider both warmth and sweat absorption, and it is best to choose thick wool socks. Wool socks have different thicknesses, and different brands have different systems. Take Smartwool as an example, divided into ultralight, lightweight, middleweight, heavyweight and ultraheavyweight series, the corresponding products will be thicker. After consumers first select the brand, they understand the thickness system classification of the product, and generally choose middleweight or heavyweight products.

In addition, there are wool socks and cotton socks on the market that use high-tech wire heating, and both materials are made of lithium polymer batteries, which have very good safety. The difference is that wool socks products have the function of breathability and warmth, and can achieve continuous heating for up to 9 hours, while relatively low-end cotton socks have a continuous heating time of about 6 hours.
If consumers feel that shoes and socks are not warm enough, insoles heated by high-tech wire will add another layer of insurance to the warmth of the live spectator. This insole is equipped with a lithium polymer battery, which can bring 6 hours of continuous heating under the premise of ensuring safety.

Cold hats, gloves, and bandanas can also be missing
In addition to warm and windproof clothes and shoes, ice and snow event practitioner Li Zhe suggested that consumers also need to prepare some other accessories to watch the game.
The first is to keep the head and face warm. Spectators need to be equipped with a double layer of cold hats that cover their ears, and they can choose wool or wool in the material, but be sure to choose a thick product. In addition, in windy conditions, face protection is also very important, magic bandana has better breathability, sweat absorption function, is a better choice.
Secondly, hand warmth is inseparable from gloves. Li Zhe suggested that glove products can choose cotton or fleece, low temperature environment, and the insulation effect of gloves is better than that of five-finger gloves. Of course, consumers can also choose high-tech heating gloves. It is understood that such products include multi-functional work gloves for outdoor and indoor special operations in winter, and there are also products specially designed for the audience to take photos, and such products can basically keep warm for 7 hours.
In addition, spectators can also bring a thermos kettle and put some drinks such as cola ginger soup, which can replenish calories on the one hand, and sweat on the other hand to help the body maintain temperature.
Li Zhe also said that many products on the market currently use technology, materials, etc. as marketing gimmicks, and the product price is very high. In addition, there are many products for professionals, from a practical point of view, ordinary spectators can achieve the purpose of cold protection and warmth when choosing equipment, and there is no need to choose particularly high-end products.
