One Bottle for the Whole Day

Think about a normal day. You start at home, spend hours at work or study, then head to the gym or out for a walk. A good bottle should go everywhere with you without being a hassle.

The Midnight Blue Smart Hydration Flask is made for that kind of day. It is an insulated stainless steel bottle, light enough to carry, with a deep blue finish that looks right with work clothes and gym gear.

At Work

On a work day, a bottle on your desk makes it easy to sip without getting up. This one is listed with temperature control, so it can keep a cold drink cold or a hot drink hot, depending on what you like.

It is a good size for the desk at 500 ml. If you are curious about other bottles made for long days, see our insulated water bottles.

At the Gym

At the gym, you want a bottle that is easy to grab and holds steady. The product page describes this flask as stable and spill-proof, and it is light, so it will not weigh down your gym bag.

Here is how a day might look with a 500 ml bottle:

• Fill it at home before work
• Refill it at lunch
• Refill it before the gym

That is three fills, or 1.5 litres, without carrying a big bottle around. Want more options for training days? See our gym water bottle range.

Outdoors

The product is described as made for active lifestyles. The lid is inspired by nature, and the stainless steel body is built to handle everyday knocks. It is a handy size for a walk, a park visit, or a weekend outing.

Why Stainless Steel?

Stainless steel is strong and does not hold onto smells the way some plastics can. It is also a reusable choice. If you would normally buy one bottle of water a day, one reusable bottle used daily for a year can replace up to 365 of them.

Gifts and Team Orders

At $19.95, this bottle sits just under a $20 budget, which makes it handy for Secret Santa, birthdays, and thank-you gifts. A few examples:

• Two bottles, one for work and one for the gym, cost $39.90.
• A team of six comes to $119.70.
• Eight bottles come to $159.60, which is over the $150 free shipping line for Australian orders.

Add something extra from our accessories range to finish a gift.
