Guideline offers technical shirts and midlayers designed for fly anglers who need high performance, comfort, and long-lasting durability. These garments help you adapt to changing temperatures and activity levels, providing the right balance of insulation, breathability, sun protection, and moisture management. Our midlayers are lightweight, warm, and efficient—ideal under waders or as light outer layers. Made from recycled materials, they offer high thermal performance without unnecessary bulk.
For warmer or windy conditions, our technical shirts provide sun protection, mosquito protection, quick-drying fabrics, and moisture-wicking comfort, using recycled fabrics and plant-based anti-odor technology. All garments are developed with our responsibility focus Clean All The Way. Click through and find your next favorite Guideline piece.
