You might want to know that every PRIME HD binocular has gone through rigorous waterproof testing before leaving Zen-Ray's factory floor by following the most demanding JIS 7 (Japanese Industrial Standard Level 7). What does that mean? They immerse every binocular into a 5 feet deep water tank for 3min. Only the ones that pass the test can be released. So, let it rain!
