What is the DYLN Bottle made of?

The Original DYLN Bottle is made of the highest 316 surgical-grade stainless steel available that’s non-magnetic and has superior corrosion resistance. The Insulated DYLN Bottle on the other hand is also constructed with the same 316 stainless steel interior, while having a more durable 304 food-grade stainless steel exterior. Our Bottles are BPA-free, liner-free and non-leaching.
