The included neck strap is average, with a rough feel that would probably soften after more use. The binoculars are very lightweight so it might not be an issue, but personally for every day use I would consider substituting a different strap for more comfort. The included case is also average. For me this is also a seldom-used accessory for any binoculars. The rainguard (ocular lens cover) fits and works well and was easy to install when I attached the strap to the binoculars.
The built-in objective lens caps are pretty neat. At first I thought they would be a pain to remove, but they pop in and out easily, and, importantly, didn't pop back on inadvertently while I was using them. With my daily use Swarovskis, which have separate lens covers that hang from a strap from each lens, the caps sometimes find their way back onto the lenses, and I don't notice until I start using them again and part of my view is obstructed.
