When winter fishing calls for long days in cold water, the Skwala Thermo 350 Pant delivers the warmth, comfort, and performance serious anglers demand. Designed as the ultimate under-wader insulating layer, these premium Merino wool pants combine natural temperature regulation, moisture management, and stretch mobility to keep you comfortable from the first cast of the morning to the last fish of the evening.
Built from 95% hand-selected New Zealand Merino wool with a soft, cloud-like interior and durable knit exterior, the Thermo 350 Pants provide exceptional warmth without bulk. The relaxed yet tapered jogger fit layers comfortably beneath waders while articulated knees and stretch fabric ensure unrestricted movement while wading, hiking to remote water, or rowing the boat.
And once the waders come off, you may never want to take them off—these pants feel as comfortable as your favorite sweatpants while performing like technical cold-weather fishing gear.
Nature still builds the best insulation available, and the Thermo 350 Pant harnesses the unmatched performance of Merino wool. Grown in New Zealand and spun in Germany, Skwala blends the highest-quality wool with a touch of synthetic stretch to create a technical fabric that excels in cold, wet fishing environments.
Unlike cotton layers that hold moisture and chill the body, Merino wool naturally retains heat, wicks moisture away from the skin, and resists odor buildup—making it ideal for multi-day fishing trips, travel, and extended time on the water.
The Thermo 350 Pant was engineered specifically for life under waders, but its comfort and performance make it equally at home in the cabin, at camp, or relaxing after a long day on the river.
The stretch waistband with cord adjuster keeps the pants secure without pressure under wader belts, while articulated knees and a tapered jogger fit eliminate bulk and allow full mobility when hiking or climbing over riverbanks.
Thoughtful storage includes two jean-style pockets for quick access and a secure rear zip pocket for essentials.
