Simms Waderwick Thermal Tops & Pants Set Tops Size: S Length: Approximately 67cm Width: Approximately 48cm Bottoms Size: S Cleaned. I wore these for about 3 seasons, but I no longer have the opportunity to use them, so I'm selling them. There are some pills, so I've selected "Slightly damaged or dirty" (as shown in photo 9). Catalog Description: Arctic char tend to favor the tidal estuaries of rivers that wind through some of the harshest climates on Earth. When pursuing such fish, or in situations where the cold creeps in, wear the Waderwick Thermal Layering System to ensure warmth. The soft, lightweight microfiber fleece provides high insulation and moisture wicking, and won't be fazed by storms. The thermal pants are a must-have under Simms waders. The anti-pilling treatment keeps the surface smooth at all times. The top has a 1/2 zip for easy on and off, and the fabric cuffs are designed to resist snagging.
