The Snow Peak Titanium Double Wall Cup 300 is a lightweight mug for the backpacker who enjoys a morning brew. The Titanium Cup's double walls have high heat retention properties, so your morning coffee stays hot longer. At the lip, both of the walls are welded together to make the edges thicker and smoother than a single wall cup. Titanium has low thermal conductivity, so you won't burn your mouth on the lip when you sip your drink. The Snow Peak Titanium Cup Double Wall 300 has titanium handles which hold the cup firmly when they're open, and fold compactly for storage.
