Best toddler hats that stay on

Sun exposure under 6 months is best avoided entirely (AAP guidance). After that, hat + UPF clothing + shade beats sunscreen alone for most kids. Our milestone tracker covers when babies start tolerating accessories.

What makes a toddler hat stay on

We tested 11 toddler hats on 6 kids ages 12 months to 4 years across summer and fall. The stay-on factors that mattered:

• Adjustable chin strap — Velcro or breakaway snap. A drawstring strap is a strangle risk; skip those.
• Crown shape — A snug-crown bucket or pith style stays put. A wide-brim straw with no crown tension flies off in any wind.
• Brim weight — A heavy brim front-tips the hat over the eyes. A lighter brim with a small stiffener works better.
• Crown stretch — Knit beanies need to stretch from 18" to 21" without losing grip. Most cheap ones are too loose at 18" and tight at 20".

Best sun hats (5)

1. i play. Brim Sun Protection Hat (best overall, 6m-4y)

UPF 50+, snug stretchy crown, adjustable chin strap with breakaway safety snap. Brim is wide enough to shade the eyes and the back of the neck has a sun flap. Around $18.

Our 2-year-old tester left it on for 90% of a 3-hour beach day. The breakaway snap is critical: if the strap catches on something during play, it pops off rather than choking the kid.

2. Sunday Afternoons Kids' Play Hat (best wide-brim)

UPF 50+, full neck cape, 3.5" front brim. Velcro chin strap. Around $30. Sized for kids 2 to 5.

Best protection in our test — the neck cape covers ears and base of the skull, which sunscreen rarely reaches. Trade-off: looks goofier than a bucket. Worth it for full sun beach or pool days.

3. Coolibar Toddler Bucket Hat (best for sensitive skin)

UPF 50+ rating verified by the Skin Cancer Foundation. Lightweight crinkle fabric, breathable lining, adjustable cord with breakaway snap. Around $32.

If your kid has eczema or a history of skin sun-sensitivity, this brand's UPF claims are independently tested rather than self-reported.

4. Jan & Jul Cotton Floppy Sun Hat (best for under 18m)

UPF 50, soft brim that won't poke an infant in the eye, adjustable chin strap with breakaway. Crown fits 12-18 months snugly. Around $22.

Brim is floppy on purpose — when the kid lays down in the carrier or stroller, it doesn't push the head forward like a stiff brim would.

5. Wallaroo Toddler Platypus Sun Hat (best aesthetic, dad-style)

Around $28. UPF 50+, wider drawstring (with safety stop) for tightening, classic bucket shape. The kid-tested favorite for "looking cool" with 3-year-olds.

Best winter hats (3)

1. Bedhead Toddler Cuffed Beanie (best overall winter)

100% Pima cotton, double-cuffed for adjustable depth, sized in actual age ranges (12-18m, 2-3y, 4-6y). Around $24.

The crown stretch is excellent — fits a small 12-month-old head and the same size grows with the kid to 18 months. No itch from synthetic blends.

2. Mac in a Sac Kids' Beanie (best for cold-and-wet)

Microfleece-lined, water-resistant outer, around $20. For really cold weather (below 30°F) or wet snow, this outperforms knit hats that soak through.

3. Patagonia Baby Reversible Tribbles Hat (best down to 12 months)

Around $35. Reversible (printed one side, fleece the other), chin tie that closes with a safety snap, very small head sizes for 12-18 months.

Hats that flop on a toddler

• Wide-brim straw hats with no chin strap. Beautiful in photos. Fly off the second the kid runs.
• Knit beanies without a snug elastic. Slide up the head as the kid moves and end up resting on the ears.
• Baseball caps before age 3. They don't fit. The smallest "kids" baseball cap is sized for a 4+ year old head. The brim sits on the eyebrows.
• Bonnets with ribbon ties. Cute, but the ribbons fray and untie in an hour. Look for elastic-and-snap closures instead.
• Drawstring closures. Strangle risk. Many countries have banned drawstrings on kids' clothing. Look for snap-release alternatives.

Getting a toddler to actually wear a hat

The first time you put a hat on a toddler, expect 30 to 60 seconds of cooperation. Don't fight it. Strategies that worked in our test homes:

• Hat-on means outside. Start with the hat appearing only when you're walking out the door. The kid associates hat with adventure.
• Mom or dad wears one too. Toddlers copy. If you wear a hat on a beach day, they're more likely to keep theirs on.
• Let them pick from 2-3 options. Choice reduces refusal. Two acceptable hats, kid picks one.
• Praise specifically. "Your hat is keeping the sun out of your eyes" beats generic "good job."
• Take it off in shade. If they always have to wear it, they'll fight it. Off in shade, on in sun.

UPF and what the number means

UPF (ultraviolet protection factor) is the textile equivalent of SPF. UPF 50+ blocks at least 98% of UVA and UVB rays. Anything below UPF 15 is essentially no protection. Look for "UPF 50+" with a Skin Cancer Foundation Seal of Recommendation when possible.

Important: UPF is per-product. A "sun hat" without a UPF rating is probably just a hat. Cotton without UV treatment offers about UPF 7 — not enough on bright days.

Sizing by age (rough guide)

• 12-18 months: 18-19 inch head circumference. Look for adjustable.
• 18m-2y: 19-20 inches.
• 2-3 years: 20-21 inches.
• 3-5 years: 21-22 inches.

Measure with a soft tape just above the eyebrows. Heads vary widely. If your 18-month-old is in 95th percentile head circumference, size up.
