"UVR" tubing gives extreme rot and UV resistance, exceeding that of silicone alternatives, yet parallels the grip and stretch properties of extruded natural latex. In fact, "UVR" destroys the performance of silicone in nearly every category. Archers in areas that experience harsh environments can have a peep sight tubing that looks and performs like extruded latex without the rot and cracking. Tested in the field from freezing snow to near 100° heat and it passed every test thrown at it. 3' Black, .094.
