Surpas developed them alongside its full-distance race program, including Kristian Blummenfelt's sub-seven-hour Ironman distance record.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTalk Nerdy To Me\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSurpas describes the fabric as an extremely light, woven material chosen for its aerodynamic and hydrodynamic properties rather than compression numbers. The front panel carries a visible stripe structure, and seams are placed specifically to manage airflow rather than just for fit, with clean-cut edges at the top and bottom so there's no raised seam catching on the skin during the run. A silicone gripper band sits at the top of each sleeve to stop it slipping during a long bike leg or marathon run. It's built as aerodynamic race-day kit rather than a recovery or compression product, the same category of gear worn in Surpas's Ironman and full-distance race program.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFast Facts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- Built for aerodynamics, not compression\u003c\/p\u003e\n\u003cp\u003e- Seams positioned for airflow\u003c\/p\u003e\n\u003cp\u003e- Silicone gripper band to stop slipping\u003c\/p\u003e\n\u003cp\u003e- No raised seam catching on the skin\u003c\/p\u003e\n\u003cp\u003e- Race-day aero kit, not a recovery or compression sleeve\u003c\/p\u003e\n\u003cp\u003e- Unisex fit\u003c\/p\u003e","brand":"Surpas","offers":[{"title":"White \/ S","offer_id":48012671942833,"sku":"AID-7072017369763","price":113.0,"currency_code":"USD","in_stock":true},{"title":"White \/ M","offer_id":48012671975601,"sku":"AID-7072017369770","price":113.0,"currency_code":"USD","in_stock":true},{"title":"White \/ L","offer_id":48017324409009,"sku":"AID-7072017369787","price":113.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/7659\/5377\/files\/Surpas-Insane-Calf-LDT-Sleeves-White-front.png?v=1791866414","url":"https:\/\/aidstation.com\/products\/surpas-insane-calf-ldt-sleeves-white","provider":"Aid Station","version":"1.0","type":"link"}
