The flexible gel insert freezes firm-but-flexible and fits inside any cap, hard hat, or helmet - hands-free cold, exactly where your head needs it.
Leak-resistant TPU - no gel on your head.
It's not a gimmick. Applying cool relief right to the head is a simple, drug-free approach clinicians reach for all the time - Ventra just makes it fit inside your hat.

For overheating and post-exertion strain, targeted surface cooling helps the body regulate faster. Wearing it hands-free keeps you moving.

People who work under helmets and hard hats build up real heat load. A conforming cool source at the crown is a simple, sensible way to ease it.
Heat & workplace strain
It fits caps, hard hats, and helmets - so whatever your day looks like, cold relief goes where you go.
Your head bakes under the shell by mid-morning. The thin insert sits under the suspension and keeps the crown cool - hands free, on-site.
No towel to dry out, nothing extra to carry. Pre-freeze one, slip it in your cap, and get cool relief through the hottest stretch of the climb.
No more frozen peas melting on your face. It conforms to your head and softens to a comfortable cool - relief that stays put while you ride it out.
A soft, conforming cool source worn in a cap soothes a sore spot or swelling - no awkward holding a hard ice pack against your head.
The chilled gel conducts cold straight from the pad into the crown of your head - no batteries, no fans, just steady passive cooling right where you wear it.
Pop the insert in the freezer until the gel firms up but stays flexible.
Slide it into the crown of any cap, hard hat, or helmet.
The cold transfers into your scalp while you keep working, hiking, or resting.
When it warms, swap in a frozen spare and refreeze the used one for next time.
3-pack rotation = all-day cool
Reusable hundreds of times. With three inserts you always have a frozen one ready - so the moment one warms, the next takes over.
The one thing that ruins a cheap gel pad is a leak. Ventra is built around a leak-resistant shell so cold relief never turns into a mess.
The shell flexes to conform to your hat's curve and takes daily freeze-and-use cycles without splitting - so it bends where cheap packs crack.
The cooling gel is non-toxic and stays where it belongs - inside the shell, never on your skin or your gear.
Workers, hikers, and migraine sufferers showing the insert in their own hats, in their own words.

These are a life saver for my migraines. It's the one thing that actually helps me function during an attack instead of just lying in the dark.
No leaks. Bends right into my cap and the cold lasts longer than the cheap packs I've bought before. Been using it for 3 months now.
It softens just enough to feel cool instead of shocking. So much better than holding a hard ice pack on my head.
Fits under my hard hat and honestly changed my summer on site. Kept one on for at least two hours and it stayed cold the whole time. First July I didn't feel wrecked by 2pm - I rotate the three of them and I'm set for the whole shift.
For the price I expected it to leak. It didn't. Simple and it works.
Pre-freeze one before a hot hike and it carries me through the worst of the heat. Reusable, light, no towel that dries out. Exactly what I wanted.
Try the 3-pack risk-free. If it doesn't keep your head cool, send it back for a full refund. The only risk is another summer sweating it out.
