The Peak is Ocean Bottle's rugged, insulated bottle for longer days outdoors. It's double-walled stainless steel with a secure screw-top lid and a 710 ml capacity, enough to get you through a morning of diving, a hike to the dive site, or a full day on the boat without a refill.

Like the rest of the range, it's built around a purpose. Ocean Bottle says every bottle it sells funds the collection of ocean-bound plastic through plastic-collection programmes in coastal communities.

iDive carries the Peak in fourteen colours. Pick your colour above; the price is the same across the range.
