Sombra Long-Sleeve Sun Shirt - Women's

Purchased the Sombra long sleeve tshirt. Then purchased a 2nd one in another color. Live in Colorado where I spend plenty of time outdoors at altitude, and was looking for lightweight option to protect from the sun during outdoor activities. While I was pleased with the weight of product, I’ve now had several issues where thread has pulled loose in several areas of the shirt after one wearing, causing me to question the durability of material. Was hoping to use these shirts for dog walking and hiking, but not sure they will hold up to regular use.
