iittala HotCool, designed by Björn Dahlström in 2003, combines innovative design and practical use of materials to deliver functional and versatile glasses for everyday use. The unique shape of the HotCool glass is accentuated by a detachable plastic sleeve that insulates your drink and protects your hands from heat and ice. The glass itself is heat resistant, and can withstand sudden temperature changes. HotCool reinforces many of the values iittala is committed to: functionality and versatility are combined in timeless contemporary design.
