Q + A

How do you heat the Original Heat Pack?

You can heat the Original Heat Pack in the oven, with boiling water or the microwave!

You know it's ready to use when the beeswax turns to liquid and it's not too hot to comfortably touch.

Do you ship outside of Canada?

For now we only ship within Canada. 

Tell us where you're shopping from [ so we can deliver to you next ] by joining our international waitlist!

How long does the heat last for?

This depends a little on how well the inside of the heat pack is melted!

Fully melted and worn against the body, the heat pack typically holds heat for over 30 minutes.

Where are your products made?

We’re proud to be 100% made in Canada! 

We make our heat packs by hand, ourselves, in Toronto, ON.

Our underwear is manufactured in Hamilton, ON. 

What materials do you use?

Our heat packs are made with beeswax and medical grade silicone. 

Our underwear is made with a super soft renewable bamboo, spandex, cotton blend. 

Our packaging is 100% reusable or recyclable. 

What's with the weird shape?

We make our beeswax heat packs using novel injection molding technology created by our co-founded Charlie! 

You might have noticed that the shape of our heat packs resemble other shapes you see in nature like corals, plant branches, and lungs.

Like other natural things, no two heat packs we make are exactly alike! That’s because the unique branching shape of our heat pack is the result of growing injected air bubbles, akin to growth in biology.

We’re still working to understand why this shape is optimal for energy transfer, but right now we’re happy with the super soft and squishy, seamless heat packs it makes out silicone + beeswax!
