Odd request as per the topic title. Family member is staffing a wilderness therapy program in a back-country backpacking camp site in the American southwest. By her report, incredible night skies with horizon-to-horizon Milky Way. She would love to be able to incorporate some bino astronomy as an activity for the kids -- most of whom are troubled and hail from metro areas. She needs some small, light-weight binos that she can toss in her already-too-heavy pack -- and ones that are not so precious that passing them around to inexperienced teens would be anxiety-provoking. Back in the day, I might have thought Nikon Venturer II's, or even smaller. Obviously 50mm and probably even 35mm objectives are out, weight-wise.
This group may be too sophisticated for this type of request -- would probably need to be plastic housing with decent lens caps -- but still good optics and pretty durable.
I'm also thinking a small plastic planisphere and red LED light (staff are discouraged from using phones, etc.) She's had very little astronomy exposure, apart from our few dark-site vacations and camping trips. Oh, and the two comets I showed her when she was < a year old but doesn't remember
