Here are two new [and good] ones! The first is Contigo's Luxe Spill-Proof Tumbler - 18oz double wall, 18/8 stainless steel tumbler with vacuum insulation and a spill-proof lid and straw. Available in stainless and black.
Another one is Asobu's Superb Sippy - it comes with a bendable silicone straw (the inner body straw is made of robust Tritan) and the 20oz capacity stays cold for up to 24 hours (hot for up to 12) because it's made of a copper lined, double- wall vacuum insulated 18/8 stainless steel.
