Simms’ Lightweight Baselayer Top is a next-to-skin layer for anglers who want a light, stretchy base under waders, a rain shell, or a fleece. It uses a brushed jersey knit fabric at 192 gsm, with a 92% spun polyester and 8% spandex blend. Simms finishes it with HeiQ Fresh odor control and HeiQ Speed Dry to help manage moisture and odor during long days.
Raglan sleeves are used for fit and range of motion, and flatlock seams are there to keep it comfortable against skin. Options vary by size and item color.
