To work best, your Icekap® Cool Cap needs to fit snugly on your head. We offer the cap in 4 sizes. Choosing the right one is easy. You just need to measure your head’s circumference.

To find your size, take a soft tape measure and wrap it around your head at the level where a hat would sit. You’ll want to measure the largest possible distance — so when in doubt, measure it again and take the larger number. (Round up if you’re between inches.)

Don’t have a measuring tape? Just wrap a string around your head, and then use a ruler to measure the string.

Sizing Guide

Cold temperatures have been used for centuries to soothe headache, inflammation, and general pain. Blood vessels constrict when they’re exposed to cold, which can help reduce the transmission of pain signals.

Keep your Cool Cap in the freezer (in a freezer bag, if you have one), and whenever you need relief, just take it out and put it on your head. Take a moment to tighten the straps to your desired level of compression, and then you’ll feel the relief begin to wash over you.

We designed the Cool Cap to deliver cold therapy that’s:

1. Longer-lasting, with medical-grade gel packs that stay cold for much longer than your average ice pack or cooling cap.
2. Targeted to problem areas, with 5 cooling zones, placed exactly where they need to be to deliver maximum relief. It’s easy to remove gel packs if you only want to cool one area of your head.

Combined with compression, which also helps with headache relief. Your Cool Cap comes with adjustable straps so you can decide the exact level of tightness that works best for you.

Lots of our customers report using Icekap daily, and often multiple times a day. Try starting with a 30 minute session to see how your body responds to it, and then increase the time as you become more comfortable with the therapy.

We offer a 60-day, no-questions-asked, money back guarantee. If you aren’t satisfied with your Cool Cap for any reason, email us at support@icekap.com and we’ll arrange a refund or exchange.

Medical-grade gel packs are manufactured to the highest standards, and are designed to stay cold for much longer than a conventional ice pack — remaining below room temperature for 2-3 hours, on average, compared to less than 30 minutes for consumer-grade packs.. Medical-grade packs are also much more durable, and stay soft and malleable when cold — so they can perfectly conform to your head or body.

If you start from room temperature, your packs should be cool enough to use after about 4 hours in the freezer. But because they’re medical-grade packs, they’ll continue to get colder for up to 24 hours — at which point they’ll be colder and last longer than your average ice pack.

If you prefer, you can buy a second set of gel packs so you always have some in the freezer even when you're wearing your Icekap Cool Cap.

You certainly can! Some people find relief from applying warm compresses to their head, and you can do that with your Cool Cap. Just take the gel packs out of the cap and microwave them in 10-second increments, or submerge them in warm water. But be careful, as the packs can get very hot if overheated.

Your Cool Cap has 5 pockets for gel packs: 1 across the forehead, 2 on the temples, 1 across the back of the neck, 1 on the top frontal region of your head. We designed it this way because these are the most common regions that headache sufferers experience pain.

If you’re only looking to soothe specific regions, just remove the packs from the pockets where you don’t want the cold temperatures.

You should definitely consult with your doctor first if you believe you have a head injury. But head cooling has been shown in studies to reduce inflammation and support recovery*, so Icekap is definitely something that could help.
