Simms SolarFlex Hoody
The Simms SolarFlex Hoody is the best-in-class fishing base layer for anglers who need integrated sun protection and maximum mobility, offering high UPF coverage and four-way stretch tailored to on-water movement. It earns its position by focusing on fishing-specific details like a protective hood and longer cut, and although it's a premium-priced option compared with more general-purpose layers on this list, its durability and targeted protection deliver a lower cost-per-season for frequent anglers.

Under Armour ColdGear Base 4.0 Crew
The Under Armour ColdGear Base 4.0 Crew is the market leader for cold-weather fishing base layers, providing concentrated thermal insulation and a compression fit that preserves core warmth during ice fishing and chilly mornings. It typically outperforms lightweight merino and cool-weather synthetics in raw insulating power for its price point, though it trades some natural odor control and breathability compared with wool blends.
