You’ll see a few names for these on Walmart.com. The most common are:

• Earflap beanie: A knit beanie with built-in ear coverage.
• Trapper hat or trooper hat: Usually bulkier, often with faux-fur or fleece lining and long ear flaps.
• Ushanka: A trapper-style hat inspired by classic Russian designs.
• Peruvian hat: A knit cap with tassels and flaps that cover the ears.
• Beanie with brim/visor and ear flaps: Adds a small bill for shade and snow deflection.

Product titles may mix terms, so it helps to scan features (ear flaps, lining, brim) and use filters under Hats, Gloves & Scarves.

Covering your ears can help retain warmth and reduce wind exposure, especially in cold or gusty weather. Many shoppers prefer:

• Earflap styles for full coverage on very cold days.
• Cuffed beanies that can be pulled down over ears or folded up in milder temps.
• Brimmed options if you want extra shade or snow deflection.

For high‑output activities, a lighter or moisture‑wicking knit may feel more comfortable, while fleece or sherpa linings can offer added coziness for everyday wear. Fit and comfort vary by person, so adjusting the cuff or choosing earflaps gives you flexible coverage.

Most adult knit beanies are stretchy, one-size fits, but you’ll also find oversized or L/XL options for roomier wear. For the best fit:

• Measure head circumference around the widest part, just above your eyebrows.
• Check the product description for size notes (e.g., one size, XL, or listed inches/cm).
• For kids, look for age ranges on the page (e.g., 0–36 months, 2–12 years) and compare to measurements when available.

If you’re between sizes, a cuffed knit often offers a bit more adjustability. Reviews on the product page can also give helpful fit feedback from other customers.

Care instructions vary, so always check the tag on your specific item first. In general, many knit and fleece-lined beanies respond well to:

• Hand washing or gentle cycle in cold water with mild detergent.
• Turning the hat inside out to help protect the knit and lining.
• Laying flat to dry to maintain shape; avoid high heat.
• Removing detachable parts (like lights or batteries) before washing, if included.

These steps can help maintain softness and fit, but results may vary based on materials and construction. When in doubt, spot clean and air dry.

Look for features that help trap heat and block drafts:

• Insulated linings like fleece or sherpa for added coziness.
• Double-layer knits or waffle/grid patterns that add warmth without much bulk.
• Longer ear flaps and optional chin ties to reduce wind lift.
• Wind-resistant or waterproof shells for wet or blustery conditions.
• Merino or moisture-wicking blends for warmth that manages sweat during activity.
• Brims/visors to deflect snow and light.

Not every hat includes all of these, so choose the combination that matches your weather and activity. Product pages typically list materials and construction details to help you compare.
