Why we made these

You built a sauna habit for the long run. Finish the setup.

Most of us came to the sauna for the same reasons: to recover after training, to unwind, to stay in shape for the decades ahead. You already sort out the details: water, electrolytes, a hat for your head, a sensible session length.

The one part of a man's body that is built to sit a little cooler usually gets no thought at all. It sits there in the full heat, session after session.

We didn't think the answer was to sauna less. We thought the answer was better kit.

Who they're for

Made for two kinds of sauna regulars

🔥 The sauna regular

Three, four, five sessions a week. You sauna for how it makes you feel and you want to keep getting the most from the habit. The pocket lets you stay in for your usual session with one area kept cool.

⏳ The man thinking long term

Forty, fifty, sixty and planning to stay active for years. You care about doing your habits well, not just often. Cotton next to your skin, a cold pack in front, nothing to fuss with.

The usual workarounds

A wet towel slips. A loose ice pack slides. A cold shower comes after.

Cooling down after you get out is a good habit. But it happens once the session is over. Holding a towel or a pack in place for 15 minutes isn't relaxing either.

Keep the heat. Keep one spot cool. A zip pocket in the front of a cotton brief does the holding for you, for the whole session.

How it works

Four steps. Zero fuss.

1

Freeze

Put the ice pack in the freezer before you head out.

2

Zip

Slide it into the front pocket and zip it shut.

3

Wear

Pull them on. The pocket keeps the pack where it should be.

4

Sauna

About 30 minutes of cold at 80°C, by our own use.*

Built simple

Cotton briefs. Clever pocket.

❄️ Cool where it counts

Cold goes to one spot, the rest of you still gets the full sauna.

🔒 Stays in place

The zip pocket holds the pack while you sit, lie down or move.

🌿 Cotton layer

Cotton sits between the pack and your skin. 100% cotton, waistband too.

♻️ Use again

Refreeze the BPA-free pack and go again next session.

Questions

Good to know

How long does the ice pack stay cold?

About 30 minutes straight from the freezer in an 80°C sauna. That's from our own use, not a lab test, so your sauna and session may differ.

What are they made of?

100% cotton, including the waistband. The ice pack is BPA free.

How many ice packs come with each pair?

One per pair. Spare packs are A$7.99.

How long does delivery take?

Usually arrives in 3–6 business days. Shipping is free over A$100.

Can I return them?

30-day returns on unopened pairs. For hygiene reasons opened briefs can't be returned. Faulty pairs are replaced free. Not sure on size? Check the size chart or message us before you order.

Do they replace medical advice?

No. They're a comfort and keep-cool product for sauna sessions. If you have a health question, talk to your GP.
