MATERIAL : Recycled Polyester WATERPROOF : No Waterproof OPTIONS : BEGINNER AGE : BEGINNER AGE : BEGINNER FREQUENCY : OCCASIONAL WEATHER CONDITIONS : COLD WEATHER Quantity : 1 U Size : XS/S, M/L, XL/2XL How is usage temperature measured? : All our gloves are laboratory tested on a thermal hand. The minimum temperatures for use (recommended and limit) are the result of a study carried out with a test panel of 23 walkers exposed to temperatures ranging from 5C to -20C and 10 km/h winds. These temperatures are only valid in walking conditions. The Trek 100 liner gloves have a heat rating of 1 out of 5. Recommended temperature: 8C Limit temperature: 3C How to properly protect your hands from the cold : By applying the layering principle, you can optimise the insulation of your hands. Consequently, by wearing liner gloves in addition to gloves, several air gaps are created around your hands, which provide effective insulation from the cold. To achieve this, the gloves must be big enough not to compress your fingers. This is because the compression slows down the blood flow in the fingers, which prevents them from keeping warm. How to keep your hands warm with the right clothing : When active, the body generates heat which is preserved thanks to the thermal insulation of your clothing. If the clothing is inadequate, your body cools and the blood flow to the hands and feet drops in order to keep your upper body warm. Your clothing can therefore play a role in keeping your hands warm. WHAT IS RECYCLED POLYESTER? : By recycling plastic bottles and used textiles to produce our polyester, we reduce the use of petroleum resources while preserving the qualities and performance of the material during use. What does the dexterity of a glove refer to? : The dexterity of a glove is its ability to handle objects with ease. Our liner gloves have been given a score from 1 to 5 in a laboratory study. The closer the score is to 5, the easier it is to handle objects as if you weren't wearing gloves. The dexterity of these fleece liner gloves was rated at 4/5.In particular, tests were done to measure how easily it is to get a jacket on and open it with these liner gloves.
