Brief Description: [WOLFILIST] Inner Cap Cycle Cap Autumn and Winter Helmet Inner Hat Cold Protection Windproof Skull Cap Beanie Fleece Lining Thermal Ear Warmers Unisex Bicycle, Skiing, Mountain Climbing, Running Hat Detailed Description: Are you worried that the temperature is dropping and you can't exercise comfortably because of the cold wind outdoors? We recommend the helmet inner cap designed by FLYING TERN. 【Thermal and Windproof Cycle Cap】The outer side of the cycle inner cap uses excellent windproof and waterproof materials to protect against cold wind and rain. The inside of the cycling cap uses a soft fleece lining, providing warmth and comfort. In addition, the sides of the cycle hat are long, and you can also put your ears inside. It is also ideal for cycling in extremely cold weather! 【Elastic Inner Cap】The helmet inner cap adopts highly elastic fibers. With its excellent elasticity, it has a sense of tension on all four sides, allowing you to wear it comfortably without fatigue. It fits perfectly regardless of head size. Free size, unisex. 【Comfortable Helmet Cap】The helmet inner uses breathable and moisture-wicking fabric, which keeps you warm while preventing stuffiness. Worn under a helmet & hat, it quickly absorbs sweat from the head and prevents uncomfortable sweat dripping. The sweat-absorbent, quick-drying, and cooling material suppresses stickiness caused by sweat, and a refreshing feeling lasts. The inner cap keeps the inside clean and comfortable. 【Small Functionality】We have pursued ease of use and added convenient functions. The cycle cap has glasses holes on both sides, so it won't get in the way even if you wear glasses/sunglasses/goggles while riding a bicycle. 【Wide Range of Uses】With specifications that are perfect for cold protection in the cold winter months, this is a high-performance balaclava that is active in winter climbing, high-altitude mountaineering, snowboarding, and severe winter backcountry tours. Applicable to various places such as bikes, bicycles, cycling, outdoor activities, and mountain climbing, it can also be used as an inner cap for helmets.
