What Our Gearhead(R) Experts Are Saying:"This is my pick when I want flannel style with technical performance. The nylon/poly blend dries fast and feels lighter than traditional cotton flannel, which makes it great for hiking or travel. It holds warmth well in cool weather, and the HeiQ odor control helps on multi-day trips. A solid lightweight layer that punches above its weight."When fog rolls in and the trail disappears into towering trees, we reach for the Lost Coast Flannel Long-Sleeve Shirt. Royal Robbins takes the timeless plaid look and infuses it with high-performance materials built for rugged hikes and extended basecamp stays.

A C0-DWR finish adds light weather resistance, while two secure patch chest pockets keep essentials close. Inspired by cool coastal landscapes, this tech flannel is built to move seamlessly from trail to camp.
