The NRX Neptune strap is based on the original NRX strap but with the Neptune textile laminated on the inside. Neptune is a hydro-dynamic material that is skin friendly and dries quickly. It has a controlled elasticity with a slightly high compression than the NRX strap. This makes it suitable for dynamic extension and flexion applications or applications where a softer inside is preferred. The CR foam core is 0.7mm and microperforated. The Neptune strap is great for applications which require compression and breathability or moisture absorption. Washable in 60 degrees Latex Free Comes in 30, 60 or 120mm widths.
