We purchased the tudi wraps to bring on vacation. We LOVE THEM!!! They did not fit around the mugs in our VRBO so we had to buy mugs that were not as big around. They are perfect for cold beverages as they prevent the glasses, beer, coolers, water, etc. from sweating and leaving pools of water under your glass. It would be great if they sold some XL ones that were 1 - 2 inches longer.
