This $10 stainless steel insulated tumbler is almost identical to a $30 Yeti tumbler

Looking for an insulated travel tumbler? Consider this $10 Polar Pad Drifter Vacuum Insulated Stainless Steel Tumbler (30-ounce). It's nearly identical to the 30-ounce Yeti, but 1/3 the price. If 30-ounces is too big, Polar Pad has a 20-ounce model, also for $10. The nice thing about vacuum insulated tumblers like this is that condensation doesn't form on the surface.
