Hydro Flask 710ml Lightweight Wide is 25% lighter than classic bottles from Hydro Flask.

The Trail series is made from an even thinner wall of Pro-grade stainless steel, but is still very durable. Condensation and temperature transfer to the outer layer is prevented by the TempShield™ technology, which keeps the contents cold for up to 24 hours or warm for up to 12 hours. It's also lighter thanks to the Honeycomb™ insulating honeycomb cap, perforated handle and aluminum joints.

It is intended for the most difficult endeavors (ski touring, climbing, cycling), where weight is essential.
