Multi-climate Cover & Long Hot Water Bottle


Throw a big wave to the Big Plastic Pledge and help support Hannah Mills MBE, founder, two time gold Olympian and IOC Sustainability Advocate on her golden voyage of eliminating single-use plastic in sports.

Support the cause by purchasing your very own Limited Edition Big Plastic Pledge (BPP) YuYu Bottle where 25% of the sales proceeds will go towards supporting the Big Plastic  initiative and make your pledge by lessening your plastic use altogether.

What's different?

Our traditional YuYu cover has had a multi-climate upgrade!
The Big Plastic Pledge YuYu Bottle is designed with a water-resistant lining with zip closure, so when you ice your YuYu rubber bottle, the condensation stays inside the water-resistant lining and not on you.

Ways to use the YuYu Bottle

1. For the ULTIMATE eco cool down

Freeze time: 2-4+ hours

Fill bottle half-way and freeze for 2-4+ hours or until icy and slushy. Then wrap it, hug it or sling it around your body to give you an eco cool down, and get you through those hot days and nights.

Cool down in bed and go green by turning your AC off and cool down the natural way. Take your YuYu to bed to keep your entire body cool—or just lay by your feet—throughout the night and wake up feeling refreshed! 

The new design works great for your sore muscles and joints to reduce inflammation and swelling.

2. A traditional YuYu warm up (best used with a padded cover) 

Heating time: Fill bottle with approximately 1.5 litres of water (about half-way) with water that’s just off the boil.

Note: To prolong the use of the YuYu Bottles, it is strongly advised to separate the hot and cold use of the rubber bottles. To purchase a second YuYu rubber bottle, head to the Accessories page.

All our hot water bottle covers, except the Cashmere Collection are machine washable at 30°.

We recommend that cashmere covers are hand washed and laid gently on a flat surface to dry. You can use a cashmere comb to remove any pilling that may occur. Cashmere combs are available to purchase with your cashmere YuYu Bottle.

When not in use, keep your YuYu Bottle empty of water and stored in a cool, dry, dark place. We recommend hanging the bottle upside down with the stopper off so that the bottle becomes completely dry inside. The bottle should be kept away from direct exposure to sunlight.
