There are plenty of reasons you might want a Hydro Flask deal. Hydro Flask makes some of the best water bottles you can buy; they're tough enough to withstand knocks, their double-walled vacuum insulation maintains your drink's temperature, and they look great thanks to their clean lines and colourful powder-coated finish. Needless to say, having some Hydro Flasks dotted around your studio could give you some serious cool points.

They're not just for water, either. Hydro Flask has a wide range of other insulated bottles and cups for everything from coffee and tea to soup and stew. All are lined with professional-grade stainless steel that doesn't hang onto tastes and odours, and many are dishwasher-safe as well.

A Hydro Flask is great if you've been looking for a way to cut down on single-use plastics, but don't want to spend money on something that's poorly designed or easily broken. In the unlikely event that anything does happen to it, each Hydro Flash bottle and cup comes with a lifetime warranty, so you can simply contact the company for a replacement. With all that in mind, we've tracked down the very best prices for a range of Hydro Flasks. With so much choice, there's sure to be something that's your cup of tea.

01. Hydro Flask 21oz Standard Mouth Bottle

Hydro Flask's famous water bottle in a convenient travel size

Specifications

Volume: 621ml

Mouth diameter: 1.91in

Diameter: 2.87in

Height: 9.4in

Weight: 11.3oz

Reasons to buy

+Easily fits into a bag +Choice of different caps

Reasons to avoid

-May be too small -Tricky to fit ice inside

The Hydro Flask 21oz Standard Mouth Bottle is hugely popular, and for good reason – it's a handy size that'll slip easily into a bag, and it'll keep your drink cold for 24 hours, or hot for six hours. It comes in six colours, with a tough powder-coated matt finish, and its stainless steel construction means it can take its share of knocks around the studio. This bottle is supplied with Hydro Flask's Flex Cap as standard (with honeycomb-style insulation to help maintain a constant temperature), but you can choose a sports cap instead if you prefer, which may be a good choice if you're concerned about spillage on your desk.

02. Hydro Flask 32oz Wide Mouth Bottle

A larger capacity and a wider neck for faster filling

Specifications

Volume: 621ml

Mouth diameter: 1.91in

Diameter: 2.87in

Height: 9.4in

Weight: 11.3oz

Reasons to buy

+Easier to fill +Simple to clean

Reasons to avoid

-May not fit inside bags -No sports cap

The Hydro Flask 32oz Wide Mouth Bottle is easy to fill in a hurry, and its larger neck means you can easily pop a few ice cubes inside to keep your drink extra cold for hours on end. It's also easier to clean than a narrower bottle (though you'll still want to use a bottle brush to make sure you're getting all the way inside). This larger capacity bottle won't slip into your bag as easily as the 21oz one above, but the handle makes it easy to carry, and you won't need to get up from your desk to refill it so frequently. There's no sports cap option for the Wide Mouth Bottle, but Hydro Flask produces a version with a built-in straw instead.

03. Hydro Flask Oasis 128oz

The best Hydro Flask for serving the whole team

Specifications

Volume: 3.79l

Mouth diameter: 4.4in

Diameter: 5.8in

Height: 14.8in

Weight: 4.96lb

Reasons to buy

+Flexible carry strap +Bevelled base for improved grip

Reasons to avoid

-Overkill for one person -Expensive

If you're working somewhere without a water cooler or easy access to a coffee machine, the Hydro Flask Oasis could be just what you need, holding enough of your chosen beverage to keep you going all day. This huge flask holds almost four litres, and has two lids: a smaller one for pouring, and a large one that you can remove for easy refilling and cleaning. The downside is that the Oasis is rather expensive, though Hydro Flask's lifetime warranty takes some of the sting out, and you can also put it to good use for picnics, camping trips and parties when you're not at your desk.

04. Hydro Flask Tumbler 16oz

The perfect replacement for all those takeaway coffee cups

Specifications

Volume: 473ml

Mouth diameter: 3.4in

Diameter: 3.4in

Height: 6.1in

Weight: 9.1oz

Reasons to buy

+Insulated lid +Super lightweight

Reasons to avoid

-Small capacity -No handle

The perfect replacement for all those disposable single-use cups – just hand over the Hydro Flask Tumbler in your favourite coffee shop and enjoy your hot drink guilt-free. While the Hydro Flask Tumbler doesn't collapse flat like some reusable cups, it offers much better insulation and won't acquire the same unpleasant taste as rubber cups tend to. It also fits in most cupholders, so you can use it when travelling between meetings. Just make sure you pay close attention when you're ordering the Tumbler because not all retailers include the press-on lid, which is essential for keeping the contents hot.

05. Hydro Flask Coffee Mug 12oz

No more cold cups of coffee or tea with this Hydro Flask mug

Specifications

Volume: 355ml

Mouth diameter: 3.5in

Diameter: 5in

Height: 4.5in

Weight: 11.2oz

Reasons to buy

+Soft-touch finish +Press-in lid

Reasons to avoid

-Expensive for a mug -Not 100% water tight

If you prefer to make your own hot drinks, the Hydro Flask 12oz Coffee Mug is the perfect vessel for the job. No longer will you find yourself in the frustrating situation of creating the perfect brew, then having it go stone cold while you're caught up in work and client emails. The mug's press-in lid fits securely and provides insulation to keep your drink hot for hours, and its soft-touch finish means it's comfortable to wrap your hands around in a chilly office. It's much pricier than a regular ceramic mug, but we think the benefits easily justify the cost.

06. Hydro Flask Coffee Flask 12oz

For a perfect, piping hot cup of coffee, wherever work takes you

Specifications

Volume: 354ml

Mouth diameter: 2.28in

Diameter: 2.91in

Height: 6.3in

Weight: 8oz

Reasons to buy

+Wide neck for easy cleaning +Works with most coffee machines

Reasons to avoid

-Only holds one cup -No carry handle

For enjoying a brew away from your desk, the Hydro Flask Coffee Flask 12oz is a great choice. Its wide neck means it's easy to fill from a kettle, but its relatively squat design means it fits under most coffee machines as well, so you can take your preferred Nespresso drink on the road. This 12oz version is small enough to tuck neatly in your bag and holds a standard size cup of coffee, but larger versions are available if you need more caffeine to get you going in the morning. It's also compatible with Hydro Flask's Wide Mouth Straw Lid, which makes it ideal for iced coffee too.

07. Hydro Flask Food Flask 12oz

Piping hot soup and stew for lunch, without a microwave

Specifications

Volume: 354ml

Mouth diameter: 3.07in

Diameter: 3.46in

Height: 5.5in

Weight: 11.1oz

Reasons to buy

+Extra wide neck for cutlery +Large lid easy to grip

Reasons to avoid

-Only stays hot four hours -No carry handle

Your studio might not have a microwave, but with the Hydro Flask Food Flask 12oz you can still enjoy a hot lunch from home. This flask has an extra wide neck to accommodate forks and spoons, and its stainless steel interior doesn't cling to food odours like plastic Tupperware. This it the smallest size, but larger Food Flasks are available if you have a larger appetite. Just make sure you don't leave your lunch too late; this Hydro Flask has a larger lid than those intended for drinks, which means it doesn't have quite the same level as insulation and will only keep food hot for around four hours.
