Optionally, each of the radial vents 21-28 and air channels 30-36, 40-48, 51-56, 60-68 may be formed in the soft-sided helmet 10 during the molding process. Optionally, the molding process may involve forming two opposing hemispheral portions 16, 17. The hemispheral portions 16, 17 may be joined after the molding process. For example, the hemispheral portions 16, 17 may be joined along a central equator 15. Optionally, the hemispheral portions 16, 17 may be joined using an adhesive, electrothermal melt joining, sewing, or another suitable technique.
