Simms' warmest mid-layer for the coldest fishing days, the Women's Thermal Jogger features a toasty grid fleece that traps heat, without adding bulk or limiting motion when layered with waders or bibs.

• A smooth knit face with a grid-fleece backside allows for heat-trapping, moisture-wicking, and stretch
• Wide, comfortable stretch waistband with adjustable drawcord
• Front drop-in hand warmer pockets
• Knit cuffs at the bottom hem for stay-put performance when layering
