The 8x42 H2O Roof-Prism Binocular from Bushnell delivers a fogproof housing and rubber armouring textured with soft ridges to maintain grip. This roof prism binocular offers a more compact footprint than comparable Porro prism designs. A multicoated lens system and high-transmission BAK4 prism glass allow these weather-sealed glasses display clear and bright images that are crisp with detail. This version of the H2O binocular comes ready for the trail with a case, strap, and lens cloth in clamshell packaging.
