The 18x50 IS was not designed to be habitually worn around the neck, but if you prefer to carry your optic in this manner then consider a thick neoprene strap instead of the supplied flat woven strap. If you'll be using the binoculars in cold weather, it is highly recommended to use lithium batteries (optional) instead of alkaline.
The 18x50 IS is threaded to accept 58mm filters, which is convenient for using polarizers around water, but it also means that during extremely bright or humid conditions you can use a pair of 58mm lens hoods to help shield the objective lenses from dew and stray light, thus improving contrast.
