WHENEVER IT WENT VIRAL

A robe with the personality of someone who hates mornings

It looks like a very grumpy Christmas character and behaves like a hot water bottle with sleeves. The body is double sherpa, the hood is lined, the hem runs to the floor and there are pockets for your feet at the bottom, so you can sit through the whole film without your toes leaving. Inside the back panel a carbon-fibre heating pad gives three real settings, powered by any USB power bank in the hidden pocket.

HEAT

Three settings, up to 50 C

One press on the cuff button for low and the sofa, two for medium on a cold morning, three for high after you have been outside. The pad holds the temperature and cuts out if it gets too hot.

POWER

Runs on any USB power bank

Slide your phone charger bank into the hidden inside pocket, plug in the USB-C lead and you are cordless. Roughly six hours on low, two on high. No trailing cable and no hot plug in the small of your back.

COMFORT

Double sherpa, floor length, foot pockets

Two layers of brushed sherpa, an oversized lined hood, elasticated cuffs and a hem with pockets for your feet, so the whole leg is sealed in and your toes never leave the blanket.

CARE

Wash the whole robe

Unclip the heating panel from the back pocket and put the robe in the machine at 30 C. The panel wipes clean with a damp cloth. No dry cleaning and no hand-washing ritual.

Warm in three moves

  1. 1

    Put it on, hood up, feet in

    Slide your feet into the hem pockets. That is the whole trick, and it is why your toes stay warm through the entire film.

  2. 2

    Power bank in the pocket

    Any 5 V 2 A bank, USB-C lead clipped to the inside pocket. Nothing to plug into the wall.

  3. 3

    One press, two, three

    Low, medium, high. The button glows so you can find it in the dark, and it cuts off if it overheats.

Questions, answered

Does it come with a battery?

No. It runs on any standard USB power bank (5 V 2 A) that sits in the inside pocket. A 10,000 mAh bank gives roughly a full evening on medium.

How long does it stay warm?

About 6 hours on low, 3.5 hours on medium and 2 hours on high, depending on the capacity of your power bank.

Is it safe?

It runs on low-voltage 5 V with an automatic cut-off if the panel overheats, and the panel is removable so nothing electrical goes in the wash.

Which size do I need?

S/M fits up to 5 ft 6, L/XL fits 5 ft 7 to 5 ft 11, XXL fits 6 ft and above. The robe is deliberately floor length, that is the point, so size for the length you want.

Can I wash it?

Yes. Unclip the heating panel, machine wash the robe at 30 C, and wipe the panel with a damp cloth. Do not tumble dry the panel.

Is this an official Grinch robe?

It is our own green grump character, not a licensed Dr. Seuss product. Same grumpy Christmas energy, no licence fee, and the quality is where the money went.

30 days to change your mind

Wear it for a month. If the heat is not what you hoped, or the grumpiness does not suit you, send it back within 30 days for a full refund. Faulty items are replaced free.
