The Cozzy Thermal-Lock Hood System (Rated -16°F)
Standard beanies leave your neck exposed. Scarves unravel and get caught in machinery. The Cozzy Thermal-Lock™ Hood is a single-unit thermal defense system. It drapes over your shoulders to create an airtight seal between your jacket collar and your helmet—trapping body heat while venting sweat. Whether you are plowing snow at 3 AM or working on a wind-swept scaffold, this is the final layer of armor your work gear is missing.

Survived midnight farm chores at -16°F.
The windchill was -16°F last night. I was out there for hours fixing a fence and I was actually sweating. The only reason I stayed warm. The fleece pulls the sweat away so you don't freeze when you stop moving. Best piece of gear I've bought in years.

Finally, something that fits under a hard hat. I've tried every beanie and mask out there. They all bunch up under my helmet or slide down. This hood lays flat and seals the gap at the back of my neck perfectly. I wear it on the lift 10 hours a day and never have to adjust it. No more freezing neck.

Blocks the wind in an open cab. I run an open-cab skid steer for snow removal. Usually, the wind cuts right through standard fleece masks. This thing blocked 30mph gusts without an issue. Plus, my safety glasses didn't fog up because the breath actually vents out. Essential kit.

Why Do Most Cheap Masks Leave You Wet & Frozen
Standard masks act like a sponge. They absorb your breath and sweat until the fabric is soaking wet. Then, the wind hits, and that wet fabric freezes directly to your skin. On a job site, that isn't just uncomfortable—it’s a safety hazard that forces you to stop working.
This equipment failure puts you at risk for:
- Freezing Sweat: Wet fabric draws heat away from your face 25x faster than air, risking frostbite during heavy labor.
- Fogged Safety Glasses: Trapped breath shoots upward, blinding you while operating machinery or driving.
- "Job Site" Rash: Cheap synthetic blends trap bacteria and scratch your skin during 12-hour shifts.
The Solution:
The Cozzy Thermal-Lock™ Hood uses hydrophobic fibers that push moisture OUT, not in. The breath-exhaust design prevents fogging, keeping your safety glasses clear. It fits loose enough to breathe, but tight enough to block 30mph wind. Stay dry, see clearly, and finish the shift.

Frequently Asked Questions
Will this fit my head/face?
Will this fit my head/face?
Yes! The Cozzy Winter Fleece Mask features a stretchy, 4-way adjustable design that fits most adult head sizes comfortably. The soft fleece material conforms to your face without feeling too tight or loose. Whether you have a smaller or larger head, the elastic fit ensures it stays in place without pressure points.
Will it fog up my glasses?
Will it fog up my glasses?
No. Unlike cheap masks that blast hot air straight up into your lenses, Cozzy's ergonomic fit directs your breath away from your eyewear. The comfortable seal prevents the "chimney effect" that causes fogging. Works with prescription glasses, safety glasses, and sunglasses.
Is it machine washable?
Is it machine washable?
Yes! Just toss it in the washing machine on a gentle cycle and air dry (or low heat tumble dry). The durable fleece material holds up wash after wash without losing softness or shape. We recommend washing it weekly or whenever it gets dirty.
Will it make me feel like I'm suffocating?
Will it make me feel like I'm suffocating?
No. The breathable fleece design allows for natural airflow while blocking wind. You can breathe comfortably even during physical activity like walking, shoveling, or working. Many customers say they forget they're even wearing it.
Is the material itchy or irritating?
Is the material itchy or irritating?
Not at all. Cozzy uses premium suede fleece that's soft and gentle on skin, even for people with sensitive skin. There are no rough seams or scratchy fibers. If you've had issues with itchy wool or rough fleece masks before, this will be a huge upgrade.
How cold does it need to be to wear this?
How cold does it need to be to wear this?
The Cozzy mask works great in any temperature below 50°F (10°C). For brutal cold (below freezing), it provides excellent wind protection. For milder cold days, you can wear it as a neck gaiter or half-mask for lighter coverage. The 4-way adjustability means it works in a wide range of conditions.
Will it stay on during activity or slip down?
Will it stay on during activity or slip down?
Yes, it stays put. The elastic fit keeps it secure whether you're walking, working, or moving around. Unlike loose scarves that constantly need readjusting, Cozzy stays in place once you put it on. Many customers wear it during dog walks, outdoor work shifts, and active commutes without any slipping.
