Outlast works as a thermal shock absorber by slowing the rate of temperature change within a wearer's personal microclimate and reduces the rate at which a person will overheat or get cold.\u003c\/span\u003e \u003cspan class=\"redline-tooltip__arrow\" data-js=\"Tooltip.Arrow\"\u003e\u003c\/span\u003e \u003c\/span\u003e \u003c\/span\u003e \u003c\/span\u003e Shirt\u003c\/h3\u003e\u003cp\u003eThe Rukka Outlast Shirt works to keep the rider’s temperature not too hot, not too cold, but just right, over a broad range of environments and activity levels. When your activity level or the outside temperature increases, the Outlast thermocules begin to change from a solid to a liquid which provides you with a comfortable sensation of thermal equilibrium. The energy required to activate this process comes from your warm body or rising ambient temperatures.\u003c\/p\u003e\u003cp\u003eWhen you begin to cool down, Outlast thermocules begin to change back from a liquid to a solid. In this phase change, the energy that was absorbed by the thermocules while you were active is returned to you. The Rukka warranty is valid for 5 (five) years from the date of purchase against faults in material or workmanship.\u003c\/p\u003e \u003cdiv data-wrapper-for=\".helmet-dimensions\" data-wrapper-at=\"small\"\u003e\u003c\/div\u003e","brand":"Just Rev It","offers":[{"title":"SM \/ Black","offer_id":46770698617076,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true},{"title":"MD \/ Black","offer_id":46770698649844,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true},{"title":"LG \/ Black","offer_id":46770698682612,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true},{"title":"XL \/ Black","offer_id":46770698715380,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true},{"title":"2XL \/ Black","offer_id":46770698748148,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true},{"title":"3XL \/ Black","offer_id":46770698780916,"sku":"P216193","price":126.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/8801\/4068\/files\/rukka_outlast_shirt_black_750x750_9186ee70-5faa-4aef-abef-7ca96b6d7d74.jpg?v=1755273686","url":"https:\/\/justrevit.com\/products\/rukka-outlast-base-layer-shirt","provider":"Just Rev It","version":"1.0","type":"link"}
