Day 1
Coffee stays hot for the whole commute and then some
12 hours hot means it’s still warm when you get home. Fill it in the morning and stop thinking about it for the rest of the day.
Week 1
It lives on the desk, not in the bag
The proportions and the colour mean it looks right on a desk or shelf. You stop hiding it. It stays out and gets used more as a result.
Long-term
On-the-go drinking actually sorted
Pair with the Travel Cup for the On-the-Go Set — one for hot, one for everything else. Use WELCOME10 for 10% off both together.

What they say about the Mono Bottle
I've had expensive thermal bottles. This one keeps temperature just as well and looks far better.
Slim enough to fit in a jacket pocket, which I didn't expect. Twist lid is smooth and reliable.
Bought the On-the-Go Set with the travel cup. The two objects together are the best portable drink setup.
The blue is deeper and more saturated in person — very specific, very HAY.
Cold water stayed cold for 22 hours in a 25-degree room. Basically 24h as claimed.
Great build quality, no metallic taste, feels substantial. The colour choices are the real differentiator.
The beige is sophisticated — works in every context from the gym to the office.
