Cold Weather Layering Series: Part Two – Bottoms That Keep You Warm All Winter

Winter is still in full swing, and staying warm is the key to continuing the activities we love—whether that’s fishing, hunting, snowmobiling, or simply getting outside. In Part Two of our Cold Weather Layering Series, we’re focusing on the lower half of the body.

Most people own a good parka or jacket, but far fewer invest in proper insulation for their legs. If you’re heading out in winter wearing only jeans, you’re going to feel the cold fast. A smart layering system for your bottoms can make a massive difference in comfort and endurance during cold conditions.

If you missed Part One, where we covered tops, jackets, gloves, and headwear, be sure to check that out HERE . Today, we’re breaking down the best base layers, insulated pants, and accessories to keep your legs and feet warm all season long.

Base Layer Foundation: Simms Strata 200

Every good cold-weather system begins with a proper base layer. The Simms Strata 200 is a versatile piece that can be worn as thermal long johns under any pair of pants or even by itself as a lighter insulation layer under waders.

This medium-weight fleece sits comfortably next to the skin and provides warmth without excessive bulk. It’s breathable, moisture-wicking, and allows you to build layers on top without restricting movement. Whether you’re fishing or heading out for everyday winter activities, this is an excellent starting point for your lower-body layering system.

Mid Layer Warmth: Simms Strata 330

When temperatures drop further, the Simms Strata 330 adds another critical layer of insulation. This fleece pant features a wind-resistant outer shell and foot stirrups to keep everything in place when layered over socks and inside boots or waders.

Compared to the Strata 200, the 330 is thicker and warmer, making it a great mid-layer option for cold, windy days. These pants are designed to be worn under an outer layer and provide reliable warmth without feeling bulky or restrictive.

Everyday Winter Pants: Simms Rogue Pant

If you’re looking for something that can be worn as a standalone pant, the Simms Rogue Pant is an outstanding choice.

These look like normal casual pants but feature a heavy fleece lining that provides impressive insulation. They’re perfect for walking the dog, sitting at the hockey rink, or running errands while staying warm and comfortable.

For extremely cold days, pairing the Rogue Pant with the Strata 200 base layer creates a highly effective and versatile cold-weather system that still looks great for everyday wear.

Extreme Cold Protection: Simms Fjord Pant

When warmth is the top priority, the Simms Fjord Pant is the warmest pant we’ve ever encountered.

Built with double-layer, non-compressible fleece, these pants provide exceptional insulation while maintaining full mobility. They’re ideal for activities like fishing, hunting, and snowmobiling—especially when you’re spending long periods outside without constant movement.

We’ve worn these under waders in February and stayed warm all day. Even professionals who work outdoors, such as carpenters and tradespeople, rely on these pants because they allow for climbing, bending, and working while staying protected from extreme cold.

If you need the ultimate winter pant, the Fjord Pant is hard to beat.

Cold Weather Accessories: Socks & Footwear

Keeping your feet warm is just as important as insulating your legs. Poor circulation makes feet especially vulnerable to the cold.

Simms OTC Thermal Socks

These are the warmest socks we’ve ever worn. With a high merino wool content and over-the-calf length, they provide excellent insulation while helping wick moisture away from your boots and into more breathable layers. This keeps your feet dry, warm, and comfortable throughout the day.

Simms Bulkley Bootie

Originally designed to be worn under waders when socks weren’t enough, the Bulky Bootie has become a favorite as a winter slipper for home or the cottage. They’re warm, comfortable, and perfect for chilly mornings and evenings indoors.

With the right base layers, insulated pants, and warm socks, cold weather doesn’t have to slow you down. A proper lower-body layering system will keep you comfortable whether you’re on the water, on the trail, or just enjoying winter outdoors.
