The whisper thin yet opaque fabric has comfortable stretch and is appropriate for the hottest of weather. Easy to hand wash and air dry quickly. All the properties of technical hiking shirt but much more stylish. The sleeves look nice rolled up, held in place with the discrete little snap buttons. The option to wear them at full length is good for sun protection. The collar isn’t ideal for layering, but looks good and can be worn up for additional sun protection. I absolutely love the color and pattern choices offered by Indyeva. They are subtle yet unique. Very classy.
