The detail

Everything, in the open.

Insulation
A foil-lined, cushioned wall slows the transfer of heat from the outside in. The exact cold-retention time is published only once it’s independently verified — measured, not estimated.
What it holds
Elastic loops and a clear mesh pocket hold temperature-sensitive vials still and upright, kept in the cool interior away from the outer wall.
On the move
Built for the day a fridge isn’t an option — a commute, a warm office, a weekend away. It slips straight inside the Case.
Warranty & care
Covered by our 90-day promise. Wipe the lining clean; air fully before storing.

Good to know

The Cooling Bag, answered.

How long does the Cooling Bag keep things cool?
The Cooling Bag is insulated to keep temperature-sensitive vials cool away from the fridge — on commutes, travel days and warm afternoons. We publish the exact cold-retention figure with the finished product at launch rather than estimating it beforehand; that number is measured, then printed.
What fits inside?
The bag is sized for the essentials of a considered routine: temperature-sensitive vials held securely, with room for the Pen and its companions. It slips into a tote, a gym bag or a carry-on without announcing itself.
Can I take it on a flight?
The bag itself is ordinary hand luggage. If you travel with any medicine, check your airline's and destination's rules and carry prescriptions in their original packaging — our travel guide covers the practical detail for flying from the UK.
How do I clean and care for it?
Wipe inside and out with a soft, damp cloth and let it dry fully between uses — no machine washing. The full care guide ships with the bag and lives in our Journal.
When can I order one?
The range is new for 2026 and ordering opens soon. Join the list and we'll tell you the moment it does — UK only, 18+.
