Product Description
Peak Brew by Ocean Bottle is a 590ml insulated flask designed for coffee breaks that actually stay hot. With improved thermal performance and an insulating air pocket, it keeps drinks hot for up to 9 hours — ideal for commutes, travel days, and long stretches outdoors when you want your coffee to last.
It’s built for real carry. Peak Brew is leak-proof, using an inverted thread that tightens as pressure builds, so it stays sealed in your bag wherever the day takes you. The 360° lockable lid lets you sip comfortably from any angle, and the cupholder-friendly shape makes it easy to bring along without thinking twice.
Made from 90% recycled stainless steel, Peak Brew is designed to be used hard and kept for years. It’s tested for reliability with a reinforced body, secure lid, and rugged rubber base.
Why This Flash
Peak Brew is made for hot drinks on the move — improved thermal performance, leak-proof carry, and a comfortable lid you can sip from any angle. The inverted thread design tightens as pressure builds, helping it stay sealed in your bag through commutes, travel, and long days out.
It’s also designed with purpose. Ocean Bottle exists to stop plastic from reaching the sea, with a mission to stop 10 billion plastic bottles from entering the ocean by 2030. Every Peak Brew purchased funds the collection of 11.4 kg (25 lbs) of ocean-bound plastic — the equivalent of 1,000 plastic bottles by weight.

Product Story
Every second breath we take comes from the ocean — and Ocean Bottle was created to help protect it by stopping plastic before it reaches the sea. Their mission is to stop 10 billion plastic bottles from entering the ocean by 2030.
Here’s how the impact works: every bottle purchased funds the collection of 11.4 kg (25 lbs) of ocean-bound plastic (1,000 bottles by weight). Ocean Bottle helps set up collection points and incentivises collection within 30 miles of the ocean, including rivers and waterways. Trusted partners like CleanHub and local coastal communities gather the plastic, and local collectors are paid fairly. You can also scan refills in the app.
A Small Swap That Matters
Choosing Peak Brew helps replace single use takeaway cups with a flask you’ll actually keep using — leak-proof for real carry, comfortable to sip from, and designed to keep coffee hot for longer.
And because every bottle purchased funds the collection of 11.4 kg (25 lbs) of ocean-bound plastic — the equivalent of 1,000 plastic bottles by weight — your daily refills support cleaner waterways and healthier coastlines.
