2-IN-1 DESIGN UPGRADED - Our latest design offers 2-in-1 versatility, featuring a tumbler lid and straw. It can be used as a 32 oz tumbler and also doubles as a universal iced coffee sleeve with our silicone ring. Compatible with popular coffee brands (Starbucks, Dunkin Donuts, Dutch Bros, McDonalds, etc.) in small, medium, and large sizes.
DOUBLE-WALL VACUUM INSULATION - Our iced coffee sleeves have double-wall vacuum insulation, constructed from kitchen-grade 18/8 stainless steel. The advanced vacuum technology keeps your coffee and beverages hot for over 6 hours or cold for over 12 hours. Fits most car cup holders for convenience.
20X COLDER ICED COFFEE SLEEVE - Our double-wall stainless steel sleeve uses triple insulated technology to keep your coffee and drinks incredibly cold. It is 20X colder than a neoprene sleeve, even on hot summer days. Every sip will be as icy and refreshing as the first.
SWEAT-PROOF - Unlike traditional neoprene sleeves, our stainless steel sleeve effectively prevents sweat, keeping your hands warm and dry. No more desk puddles, table rings, or slippery hands. Niceyos makes it easy!
PERFECT GIFTS FOR ICED DRINK LOVERS - Our iced coffee sleeves from Niceyos make perfect gifts for lovers of iced coffee and cold drinks. They are engineered to last for years, even in harsh environments. Niceyos tumblers come with a limited lifetime warranty against manufacturing defects.
