Description
Full-Coverage Insulated Balaclava with 3M Flex 40 Stretch Recovery for Extreme Cold
Product Overview
The Tough Duck I361 FX40 Thinsulate balaclava covers the head, face, and neck with 3M Flex 40 Thinsulate insulation inside a 100% acrylic knit shell. Standard insulation loses warmth when stretched, but the Flex 40 lining stretches 40% in every direction and recovers its full insulation value, so it insulates the same in March as it did in November. Traditional single-opening style. Machine washable. A full face Thinsulate balaclava that stretches without losing warmth through a full winter of daily wear.
Key Features
- Stays warm all winter because the insulation recovers after being stretched from daily pull-on and pull-off
- Covers head, face, and neck with a single eye opening for full protection in one piece
- Machine washable without losing warmth or shape between washes
- Fits under most hardhats for under-helmet wear on hardhat-required jobsites
- Three color options including hi-vis Orange and Yellow for regulated sites

Frequently Asked Questions
Does a Thinsulate balaclava keep your face warm below minus 20?
Yes. The 3M Flex 40 Thinsulate lining covers the full face and head. The Tough Duck I361 FX40 Thinsulate Balaclava handles typical Canadian winter cold on its own. For sustained wind below minus 30, layer it under a parka hood.
Thinsulate Balaclava vs Thinsulate Beanie for extreme cold?
The FX40 beanie covers the head only. The Tough Duck I361 Balaclava covers the head, face, and neck. Same Flex 40 Thinsulate, same stretch recovery. Pick the beanie when your face is sheltered. Pick the balaclava when it is not.
Can you wear a Thinsulate Balaclava under a hardhat?
Yes. The acrylic knit shell sits close to the head. The balaclava adds thickness to the crown, so check fit with your specific hardhat. Most one-size hardhats adjust enough to fit over an acrylic knit balaclava with Thinsulate for winter construction.
What is the difference between a Thinsulate balaclava and a fleece balaclava?
Thinsulate traps heat through synthetic microfibers. Fleece traps heat through lofted polyester. The Tough Duck I361 uses Flex 40 Thinsulate that recovers after stretching. Fleece balaclavas do not have stretch-recovery insulation, so they may thin out faster with daily use.
How do you wash the I361?
Machine wash cold, tumble dry low. The Flex 40 Thinsulate recovers its insulation properties after washing. The 100% acrylic knit shell holds its shape. Remove before washing if wearing under a hardhat with straps or clips.
