Introducing the shirt that started it all: the Bamboo Lightweight Long Sleeve. Born from our quest to ditch heavy, sticky performance gear, we found the perfect fabric—bamboo—and crafted a shirt that’s still a bestseller today. Buttery soft, lightweight, and featuring a UPF 20+ rating, this long sleeve is your go-to for sun-soaked adventures when shade is in short supply. Whether it’s a day on the water or exploring the great outdoors, this classic shirt has you covered in comfort and protection. No question, Free Fly fabric is great when compared to synthetic when it comes to cooling, but the tailoring is not up to a snuff for a garment at this price. RE: Free Fly Bamboo lightweight long sleeve shirt, the sleeves and side seams are single needle with standing selvage, basic inexpensive t-shirt approach. When compared to the NRS silkweight poly shirt with all double needle flat seams and angel wing shoulders, Free Fly comes up way short.
