Excellent product!
I ride long distances in summer and my helmet turns into an oven after 30 minutes. I put one of these in before every ride now. The difference is immediate — and I always have a second one ready in the freezer.
We want you to feel the difference from the very first use.
Try the Holie IceCap Gel Insert in any helmet,
hat, or headwear you own.
If it doesn't keep you noticeably cooler, contact us
and we'll make it right. Every single time.
That's the Holie guarantee.
Step 1 — Freeze
Place the insert flat in your freezer for 2 hours
before first use.
Keep one in the freezer at all times — that way
you always have a fresh one ready to go.
Step 2 — Insert
Slide the insert inside your helmet or hat,
flat against the inner crown surface.
The 5-petal flexible design adapts to any shape —
no adjustment needed, no pressure points.
Step 3 — Wear & stay cool
Put on your helmet or hat as normal.
The insert sits between the liner and your head,
delivering consistent cooling for up to 4 hours.
Step 4 — Rotate & reuse
When the first insert warms up, swap it for
the fresh one from the freezer.
Rinse with clean water after each use.
Store flat in the freezer until next time.
🏍 Long rides — helmet heat is real. After 30 minutes
in summer sun, the inside of a helmet becomes
uncomfortable fast. The IceCap changes that.
🧢 Outdoor work & activity — construction, gardening,
hiking, fishing, cycling. Any activity where heat
builds up under your headwear.
☀️ Hot summer days — whether you're sitting outside,
walking, or just trying to stay comfortable,
a cool head makes everything easier.
❄️ Head tension & heat discomfort — gentle, consistent
cold at the top of the head helps you feel
more comfortable and focused during long hours
in warm environments.
👴 Everyday comfort — for anyone who finds heat
harder to manage. Simple, non-invasive,
and ready when you need it.

One insert. All day cool.
Inside a helmet, heat has nowhere to go.

The Holie IceCap Gel Insert sits flat against the inner crown of any helmet or hat.
No bulk. No pressure. No adjustments.
The premium flexible gel conforms to the shape of your head and delivers consistent cooling for up to 4 hours — through your ride, your shift, your afternoon outside.
When it warms up, swap it for the one
you kept in the freezer.
Simple. Effective. Always ready.

Any helmet or hat with an inner lining or crown — motorcycle helmets, baseball caps, hard hats, cycling helmets, sun hats, fishing hats. If it has an inner surface, the IceCap fits.
Up to 4 hours of continuous cooling after 2 hours in the freezer. For repeat sessions, 30 minutes of refreezing is enough.
No. The ultra-thin profile and flexible 5-petal design sit flat against the inner crown without adding noticeable bulk or changing the fit of your headwear.
You'll feel a gentle, consistent coolness — not a sharp cold. The gel delivers a steady temperature that stays comfortable throughout the session.
Yes. The premium gel is non-toxic and the outer membrane is skin-safe and leak-proof. If the insert ever leaks, rinse the area with water and discard.
Yes — the flexible design also works as a direct head cooling compress. Place it flat on the back of the neck or top of the head with a thin cloth between the insert and bare skin.
