主权项 1. Apparatus for resisting the crosswind effect on arrows provided with fletchings comprising: a number of pairs of fletchings spaced about a central shaft of the arrow, each of said pairs of fletchings having vertically rising surfaces having tips which are arched inwardly towards each other at the distal edges of the fletchings such that the fletchings are bowed inwardly to present minimal area to crosswinds while at the same time directing the flow of the crosswinds around the arrow.
