Iron Heart X Ocean Bottle 350ml Stainless Steel Brew Flask

Designed in collaboration with K8 in Oslo, Norway, Ocean Bottle offers an award-winning range of reusable drink containers that are both practical and ethically responsible. The innovative conservation program founded by Ocean Bottle ensures that for every bottle sold, 25 lbs of plastic (equivalent to 1000 bottles) is reclaimed from the world’s oceans and rivers, all while supporting the livelihoods of coastal communities worldwide.

This 350ml, barista-approved brew flask is constructed from recycled stainless steel and BPA-free plastic, featuring a double wall, vacuum-insulated design engineered to keep your coffee hot or your ice tea cold. Other practical features include a 360° lid to allow for aromas to circulate while sipping and a non-sweat surface to ensure the bottle remains dry and leak-free in your bag.

In an ongoing commitment to combating plastic pollution, each bottle incorporates an integrated smart chip that syncs to the Ocean Bottle app. Every time the bottle is filled, the app adds to the total plastic you’ve helped recycle, closing the loop on ocean-bound plastics and saving our seas one refill at a time.
