I have 2 red and 1 green C3 with matching Neutrinos for sale, all in great condition. They are marked 2015 on the tags, used moderately for a season and a half in 2017/2018. Kept in a haul bag in a closet when not being used. Light wear on the anodization on the nose of the biners. Asking $60 each, $160 for all three, and I will cover shipping within the lower 48.
