This produces\u003cbr\/\u003e a local decrease in forehead skin temperature.\u003c\/p\u003e \u003cp\u003eBecause the system is driven solely by water evaporation, the effect is sustained —not cold storage—\u003cbr\/\u003e as long as three conditions are met simultaneously: wet pieces, direct contact with the skin,\u003cbr\/\u003e and airflow over the pieces (generated by movement or, indoors, by a fan).\u003c\/p\u003e \u003ch3\u003eUsage Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\u003cstrong\u003eFormat:\u003c\/strong\u003e headband + 20 cooling pieces + carrying case\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003ePiece material:\u003c\/strong\u003e high thermal-conductivity graphite with hydrophilic coating\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eRe-wetting:\u003c\/strong\u003e every 30–40 min during use, with water at any temperature\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003ePre-cooling:\u003c\/strong\u003e no refrigeration or freezing required\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e pieces are removable and interchangeable between Omius headband, visor, and cap\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eTarget users:\u003c\/strong\u003e endurance athletes (running, trail, triathlon, cycling, open-water swimming) training and competing in heat or humidity\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eScientific Evidence\u003c\/h3\u003e \u003cp\u003eLocal head cooling acts on cutaneous thermoreception and, through it, on perceived exertion.\u003cbr\/\u003e Available evidence —including an independent study from Université de Sherbrooke published in\u003cbr\/\u003e \u003cem\u003eJournal of Thermal Biology\u003c\/em\u003e (2024)— shows that the technology reduces forehead temperature\u003cbr\/\u003e and improves perceived thermal comfort and perceived exertion in hot and humid conditions.\u003c\/p\u003e \u003cp\u003eThe same study found no reduction in core body temperature (rectal or mean skin) and no performance\u003cbr\/\u003e improvement in a 5 km time trial.

The porous graphite absorbs water and multiplies the evaporation surface on your forehead by ×5.\u003cbr\u003e As the water evaporates, it draws heat from the pieces in contact with your skin and cools the area.\u003cbr\u003e The effect continues while the pieces remain wet, in contact with the skin and exposed to circulating air.\u003c\/p\u003e \u003ch4\u003eDo I need to put it in the refrigerator or freezer?\u003c\/h4\u003e \u003cp\u003eNo. It only needs the pieces to remain wet during use, in contact with the skin and exposed to air.\u003cbr\u003e The water temperature does not matter: it quickly adapts to the environment and evaporation works the same way.\u003c\/p\u003e \u003ch4\u003eHow long does the cooling last during use?\u003c\/h4\u003e \u003cp\u003eIndefinitely, provided the pieces remain wet, in contact with the skin and exposed to airflow.\u003cbr\u003e In practice, simply wet them again every 30–40 minutes.\u003c\/p\u003e \u003ch4\u003eWhy do I stop feeling the cold after 5 minutes?\u003c\/h4\u003e \u003cp\u003eBecause the thermal receptors in your skin adapt and begin to perceive that temperature as their “new normal”.\u003cbr\u003e The cooling effect is still present: move the headband slightly so the graphite touches skin that has not adapted,\u003cbr\u003e and you will feel it again.\u003c\/p\u003e \u003ch4\u003eDoes it work only when it is very hot?\u003c\/h4\u003e \u003cp\u003eNo. If you feel hot, cooling helps you feel more comfortable and makes the effort feel less demanding.\u003cbr\u003e Some people use it from 15 °C, while others do not need it until 25 °C.\u003c\/p\u003e \u003ch4\u003eIs my own sweat enough?\u003c\/h4\u003e \u003cp\u003eMost likely not—it depends on your sweat rate and the environment.\u003cbr\u003e Sweat reinforces the effect, but for optimal performance it is best to keep the headband wet with water.\u003c\/p\u003e \u003ch4\u003eDoes it work in humid conditions?\u003c\/h4\u003e \u003cp\u003eYes. Air can always accept some more moisture, and with the amount of water that evaporates,\u003cbr\u003e a humid environment still allows that evaporation.\u003c\/p\u003e \u003ch4\u003eCan I use it indoors?\u003c\/h4\u003e \u003cp\u003eYes. The technology works just as well indoors, but you need a fan to move air over the pieces\u003cbr\u003e to simulate the airflow produced outdoors, and you must keep them wet every 30–40 minutes.\u003c\/p\u003e \u003ch4\u003eDo I need cold water for the pieces?\u003c\/h4\u003e \u003cp\u003eNo. The water temperature does not matter: it quickly adapts to the ambient conditions,\u003cbr\u003e and evaporation works from any starting temperature.\u003c\/p\u003e \u003ch4\u003eWhat are the pieces made of?\u003c\/h4\u003e \u003cp\u003eHighly heat-conductive graphite with a hydrophilic coating that optimizes the absorption\u003cbr\u003e and evaporation of the water that drives the cooling.\u003c\/p\u003e \u003ch4\u003eDo the pieces wear out over time?\u003c\/h4\u003e \u003cp\u003eNo. The technology works indefinitely as long as you clean it regularly\u003cbr\u003e and handle it with care.\u003c\/p\u003e \u003ch4\u003eAre they fragile? What happens if I break one?\u003c\/h4\u003e \u003cp\u003eYes, they are delicate by design, and it is normal for one to break with use.\u003cbr\u003e They are replaced by hand: push the old piece out of the grid\u003cbr\u003e and insert a replacement. Replacements are sold in packs.\u003c\/p\u003e \u003ch4\u003eCan I wear the headband under my own cap?\u003c\/h4\u003e \u003cp\u003eIt is not recommended: contact with the cap can break the pieces\u003cbr\u003e and block the airflow they need to work effectively.\u003c\/p\u003e \u003ch4\u003eDoes it improve my performance or personal best?\u003c\/h4\u003e \u003cp\u003eIt helps you feel more comfortable and makes the heat feel less demanding on your head\u003cbr\u003e (thermal comfort and perceived exertion).\u003cbr\u003e Independent research has not shown that it lowers core body temperature\u003cbr\u003e or improves time-trial performance by itself.\u003cbr\u003e It is a thermal comfort and sensation tool.\u003c\/p\u003e \u003ch4\u003eHow do I clean and store it?\u003c\/h4\u003e \u003cp\u003eAfter use, remove the pieces and clean them with water and a little dish soap to remove impurities.\u003cbr\u003e They can be stored dry in their case and wetted again before the next use.\u003c\/p\u003e \u003ch4\u003eWhat does the purchase include?\u003c\/h4\u003e \u003cp\u003eThe Omius headband and a pack of 20 cooling pieces to fill the entire grid,\u003cbr\u003e plus the carrying case.\u003c\/p\u003e","brand":"Crown Sport Nutrition","offers":[{"title":"Black","offer_id":54400200048982,"sku":"HEADCOOL.N","price":239.0,"currency_code":"EUR","in_stock":true},{"title":"White","offer_id":54400200081750,"sku":"HEADCOOL.B","price":239.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/8666\/3766\/files\/Omius-headband-White.webp?v=1782985070","url":"https:\/\/crownsportnutrition.com\/en\/products\/omius-cooling-headband-crownpro","provider":"Crown Sport Nutrition","version":"1.0","type":"link"}
