Ice Cold in 100°C Natural Cork Shell Designed in Australia
Why Hemmy

Not your average water bottle

Thermal Overmolding

Cork resin bonded directly to steel under pressure. Permanently fused — never peels at 100°C. Your hand stays cool while the sauna peaks.

Dead Zone Vacuum

Double-wall 304 stainless creates a thermal dead zone. Heat simply cannot cross it. Ice cold for 24 hours — even inside a 90°C sauna.

Natural Cork Shell

Sustainably harvested cork — nature’s best thermal insulator. Zero plastic outer layer. Feels incredible in your hand.

Safe Sauna Hydration

Proper hydration cuts heat stress risk. Cool water every round, no burned fingers — HEMMY makes it effortless.

The Difference

Generic bottle vs HEMMY

🙄 Generic Stainless Steel Bottle
✗ Exterior heats rapidly in sauna ambient
✗ Burns your hand every round
✗ Water warms up fast in the heat
✗ Conducts sauna heat directly to liquid
✗ Plastic sleeve peels or warps in heat
🔥 HEMMY Sauna Bottle
✓ Cork exterior stays touchable at peak sauna heat
✓ Cork grip stays cool to touch all session
✓ Ice cold for 24 hours straight
✓ Dead zone vacuum blocks heat transfer
✓ Cork overmold fused permanently under pressure
How It Works

Three layers of science

1

Cork Outer Shell

Natural cork acts as the first thermal barrier — incredibly low conductivity, bonded directly to the steel.

→
2

Vacuum Dead Zone

The double-wall vacuum eliminates all convection and conduction between outer shell and inner chamber.

→
3

304 Stainless Interior

Food-grade 304 stainless steel inner wall — completely isolated from the sauna heat outside.

→
4

Result: 24hr Ice Cold

Your drink stays ice cold for a full day. No matter how hot it gets around it. Tested at 100°C ambient.

The HEMMY Playbook

Tight niche. Strong story.

Education

Why metal burns

Generic stainless conducts sauna heat instantly — 100°C ambient means burning hands in seconds. Cork triple-wall changes everything.

Ritual & Lifestyle

Your Sunday sauna routine

Charcoal for the biohacker. Original Copper for wellness. Forest for minimalists. Every colour is a vibe, not just a finish.

Proof & Testing

Thermometer tested

Generic stainless steel heats up fast in sauna ambient. HEMMY's cork overmold keeps the exterior touchable. Real difference, real sauna.

In the Wild

On the bench.
In the heat.

Cedar bench. 100°C. Steam rising. Your HEMMY looks incredible — drink still ice cold. That’s the vibe.
