K4 "Tallboy" (48oz) Insulated Nalgene Holder

The same efficient access, rock-solid support, and insulation from the elements as our standard K4 Nalgene Holder — now for the larger 48oz Nalgene bottles. IMPORTANT NOTES While the video below does reference a pre-order, that is an old reference to last year's launch. Currently, the Tallboy is in stock and ready to ship! This is a limited-run item, which may not be produced in the future. If purchasing the bundle, you will receive the 48oz Ultralite Nalgene with a blue lid, blue Nalgene logo, and blue measurement markings on the back, as shown in the product photos above. We do not have a 48oz version of our Exo Logo Bottle Bottle Compatibility: 48oz Nalgene Bottles (sometimes called the "Silo"), either the Ultralite HDPE Bottle (4.75oz), or in the standard material, Tritan Bottle (7.375oz). Weight 4.2oz Dimensions 4" x 10" Compatibility K4 Hipbelt Built in the USA with 500d Cordura, premium foam, and custom webbing. Materials & Production Details »
