Cool ... and Hot! - Neoprene CoolWrap Bottle is designed to keep your favorite beverage COLD ... and your hands WARM ... and DRY! It will also keep hot beverages HOT and your hands COOL. The Neoprene Difference - California Springs insulator CoolWraps are manufactured from neoprene "wetsuit" rubber, the insulator industries' material of choice. Neoprene allows for tight screenpring registration, resists degradation from sun, ozone and weather, is incredibly durable and keeps drinks cold! Cheaper foam and scuba insulators are not substitute for the enduring benefits of neoprene. The Better Bottle - The California Springs bottle series is made of a soft, easy to squeeze LDPE plastic material and features our exclusive leakproof DuoFlowTM Caps. Contrasting Cap Colors - There is no additional charge for using a contrasting color cap. Choose a cap color that matches one of your imprint colors to further enhance the great look of your bottle (Please see 50+ Color Chart). Printing - Neoprene CoolWraps are printed flat, before they are assembled, enabling us to flawlessly print multiple colors. In addition to the neoprene CoolWrap imprint, Tall 28 and T 30 Bottles can be imprinted on the upper portion (neck). Fits most bike cages. Std 22 - holds 20 oz. Tall 28 - holds 26 oz.
