Outdoor Research's extremely popular Helios has taken the hiking and fly fishing community by storm. Instead of reinventing the wheel, they added a bug net to the crown  to create the Bug Helios Hat. This hat has the same UPF 50+ rating that resists the dangerous rays of the sun, and is constructed with the same breathable, moisture-wicking material. The only real difference is the band just above the brim that hides a full-face bug net to protect you from mean, biting critters.
