Narrow Mouth Cap Strap

Built for your Narrow-mouth Nalgene, the CAP STRAP adds a durable, secure attachment point without unnecessary weight. Its powder-coated aluminum ring screws through the bottle’s threads and seats just beneath the cap, giving you a dependable alternative to a plastic strap. From big-wall climbs to everyday commutes, the CAP STRAP won’t stretch and weighs just 8.5g (0.30oz). Made in the USA. Designed for 32oz and 16oz narrow-mouth Nalgene bottles. Choose your favorite color to make it yours.
