Simms Thermal Midlayer Bottom

The Simms Thermal Midlayer Bottom keeps you warm on cold days without extra bulk. First, the smooth-faced grid-fleece traps heat next to skin and layers cleanly under waders. Next, the easy stretch helps you move naturally. Finally, the simple, durable build makes these Simms thermal pants an everyday winter go-to.

Heat Without the Bulk

In short, the self-fabric waistband with dual snaps and a zipped fly make on-off changes easy. In addition, dual slash hand-warmer pockets add quick storage. Plus, a gusseted crotch improves comfort under bibs or waders, while a tapered hem gives a neat, streamlined fit. As a result, you stay warm and free to fish.
