The cold system

One floor is a freezer.

The can is divided into three floors — 8 mm for spent pouches, 20 mm for fresh, 13 mm for the ice pack — while retaining a standard diameter. At 68 mm across and 41 mm tall, it occupies the same pocket as a conventional can.

  1. 01

    Freeze the slim pack

    90 min

    Ninety minutes in a standard freezer drawer. One pack ships inside every can; a three-pack keeps a frozen spare available at all times.

  2. 02

    Load the three floors

    Three floors

    Ice pack in the base tray, twenty-five fresh pouches on the perforated floor above it, and the upper floor left clear for spent pouches.

  3. 03

    Seal and carry

    6 hours

    Closed on two silicone O-rings, the can holds fridge temperature for six hours at room ambient — flavour and moisture preserved throughout.

Cold facts

Tested before release.

6 hoursCold hold, sealed

Measured with a frozen pack, the lid closed, in a 22°C room — the length of a full working shift.

1 hourCold hold, empty tray

The same can in the same room, with nothing in the ice tray. Aluminium on its own holds fridge temperature for an hour — the other five come from the frozen pack.

90 minFreezer to ready

From room temperature to fully set, laid flat in a standard freezer drawer. Leaving it in longer does no harm, so a spare can simply live there.

One tin, one ice pack in the box.

Machined in Vancouver. Free shipping when a tin and a pack ship together, and a 30-day cold-or-refund guarantee.
