Midnight Sky Cottontrails Base Shirt (Unisex)
Midnight Sky Cottontrails Base Shirt (Unisex)
Super soft, lightweight, and built for everyday movement, the Runyon Women's Cottontrails™ Short Sleeve Base Shirt is a unisex 100% cotton shirt for women crafted from breathable cotton grown and knitted in the USA. Designed with a clean, relaxed athletic fit, this natural-fiber crew neck shirt is made for running, trail running, hiking, gym workouts, fitness, travel, and everyday wear.
The unisex fit is especially versatile for women who prefer a relaxed athletic T-shirt rather than a traditionally fitted women's style. Women can choose their preferred unisex size for a comfortable, relaxed fit or size down for a closer, more fitted look. The lightweight cotton knit is garment-washed and pre-shrunk for a super soft, comfortable feel from day one.
A classic short sleeve crew neck, knit neckline binding, and minimal backside Runyon label create a versatile women's 100% cotton athletic shirt that transitions easily from trail runs, hikes, and workouts to travel and casual everyday wear. Designed, cut, and sewn in Los Angeles, it's a natural fiber alternative for women looking to wear less synthetic activewear.
Join the Cottontrails™ movement to return to natural fibers with women's athletic and outdoor apparel made in the USA from USA-grown cotton.
