Reason for Being: Originally designed to be worn fishing the flats in warm waters, the idea behind this pant is to be as lightweight and breathable as a pair of shorts while providing much needed sun protection. These have since been picked up as a go-to piece for long trail hikers because of their durability and breathability.

Fabric: 1.5 ounce Duralite nylon is lighter than most of our pants. These are designed to feel like feathers and breath like you’re not wearing them.


UV Protection: Carries a sun protection rating of UPF 30+.


Side Vents: 27” of mesh ventilation runs from  outer thigh to calf and another strip runs down the inner thigh, making sure that you feel every breeze on a hot day.
