What it does.

Four features you can feel on night one.

See the science →

Made for the whole night.

Cold for the first 30 minutes. Dark and soft until your alarm.

First ~30 minutes · cooling

Cold you can plan around

Freeze the gel for about 2 hours. It feels coldest at first and eases off over about 30 minutes. Clear steps are printed in the box.

~2 h freeze · up to 30 min cold

All night · the wrap, no cooling

Comfortable on your side

A slim, soft wrap with no hard parts at the temples, so lying on your side doesn't mean something digging in.

Side-sleeper friendly

Fits different face shapes

Moldable padding settles around your eyes and the bridge of your nose to help keep light out. Every face is different, so fit can vary.

Moldable fit

Comfortable after the cold fades

The gel stops cooling after about 30 minutes. From then on it's a soft, dark wrap you can keep on all night. Slide the insert out to wash the wrap.

All-night wear · washable wrap

Two sessions, one day.

One on court. One with your eyes closed.

First access to nar cryoEarly access

7 hours. Minimum.

Sleep experts recommend at least 7 hours a night for adults, and athletes in hard training often need more. nar cryo is built for those hours: a wrap that keeps the light out, cold gel for the wind-down, and a nightly cue that the day is done.

You've got the magnesium.
You've got the melatonin.
Now what?

Most recovery routines stop at what you swallow. The missing piece is the space around your head at night: cold and dark.

Cold + dark · nar cryoThe missing piece

If you trained hard all day

Your body is still running hot.

After a session you often still feel warm when you get into bed. Cold gel on your forehead is a simple way to cool off while you wind down.

If you stared at a screen all day

Your eyes and head need a reset.

Hours of screens and bright light leave your eyes tired and your mind switched on. Cold on the eyes and no light make it easier to wind down.

If you're on the road

New room, same routine.

Hotel curtains, late flights, a different time zone. Bring your own dark, and a cold start to the night.

If your mind won't switch off

Give the day a clear end.

The same few steps every night: gel in the freezer, wrap on, lights out. A simple cue that the day is done.

Temperature matters. For anyone who trains, works on screens, travels, or just wants to wake up recovered.

Cold. Dark. Still.

What research says about cold, darkness and sleep. None of these studies tested nar cryo.

Cold and headaches

A 2013 randomised trial found a frozen neck wrap, used at the start of a migraine, reduced pain. It cooled the neck, not the eyes or forehead, so it doesn't show the same result for nar cryo.

[1]

Darkness and melatonin

Room light before bed delayed and shortened melatonin in a lab study. Keeping light off your eyes is the idea behind any sleep mask.

[5]

Cooling the head

A small 2003 lab study found that cooling the head kept sleep closer to normal in humid heat. It used a different cooling setup, in a lab.

[2]

Eye masks

A 2021 review of 13 studies found eye masks improved how well hospital patients said they slept. Not athletes, and not a cooling mask.

[6]

What we can and can't say. nar cryo hasn't been tested in a study. What it does for sure: it gets cold, it blocks light, and the gel comes out. We'll publish our own testing when it's done.

How to use it.

Three steps. Every night.

Place nar cryo in the freezer for 2 hours.

Gently slide it over your head.

Enjoy up to 30 minutes of soothing cold, then keep it on to block the light.

Guide times. We're confirming them on the final product, and they'll be printed in the box.

Sleep is training.

Four studies we keep coming back to.

16.2s → 15.5s

More sleep, faster sprints

11 Stanford basketball players slept close to 8.5 hours a night for 5 to 7 weeks. Sprints got faster and free throws went from 7.9 to 8.8 out of 10.

Small group, no control group. [3]

1.7×

Short sleep, more injuries

Among 112 young athletes, those sleeping under 8 hours were 1.7 times more likely to have been injured than those sleeping 8 or more.

A survey: it shows a link, not a cause. [4]

~90min

Light steals melatonin

In 116 adults, ordinary room light before bed delayed melatonin onset in almost everyone and cut its duration by about 90 minutes.

Healthy adults aged 18 to 30. [5]

13studies

Eye masks help people sleep

A 2021 meta-analysis of 13 studies and 797 patients found eye masks improved how well people said they slept.

Hospital patients, not athletes at home. [6]
