What Our Gearhead(R) Experts Are Saying:"I have been reaching for the Happy Camp Flannel on cool mornings at the trailhead and evenings around the fire all season, and it has held up beautifully to both. The heavyweight organic cotton has a really satisfying hand feel that only gets better with wear, and the side pockets are a genuinely useful detail I did not expect to appreciate as much as I do."Cool mornings at the trailhead have a way of demanding the right layer, and the prAna Happy Camp Flannel Shirt is exactly that. Built from heavyweight 100% organic cotton yarn-dyed twill, it brings the kind of warmth and structure that makes it feel more like a light jacket than a shirt, while still carrying the relaxed, lived-in character of a great flannel. The standard fit sits comfortably over a base layer or on its own, and the details are thoughtfully chosen for life outside. Dual chest patch pockets with hidden snap closures keep small essentials secure without interrupting the clean look of the shirt, while side seam pockets add hand warmth and utility when the temperature drops around the fire. Snap front closure and snap cuffs make getting in and out easy after a long day, and reinforced stitching means this is a flannel built to hold up through seasons of real use rather than just a handful of outings. Organic cotton construction rounds out a shirt that feels as good on the conscience as it does on the trail.
