Confetti Mega Mug

This mug is so pretty with all of it's vibrant colors and the white shimmery base color. It suits my personality perfectly and I am thrilled to use it all the time... at my desk, outside on the deck or at the ballfield. I love that it fits in my car cup holder without a special attachment. I can't wait to add to my collection of Swigs. There are so many pretty patterns to choose from. Thank you for the rewards program. I will be back to buy another soon.

Fun fact: I got a pack of glitter straws but the site said that they are not compatible with the Mega Mug but I just used them with the provided silicone tip and they work just fine for me :). Also, I have seen a new cup advertised that holds cups from Starbucks, Dunkin Donuts, etc and keeps them cold so I tried it with a large iced coffee from Dunkin Donuts and it worked so well. Even after 2 hours, the ice was solid and my drink was cold.

GREAT Mega mug

I could not be happier with this mega mug. Any Swig design is beautiful, but I especially like this one because it has a little texture in the plaid, allowing for a better grip. This mug holds a lot of water. I typically drink tons of water and I get tired of refilling my cup all of the time, so this one fits the bill perfectly! I love that it goes from home to car. If I had any not unfavorable comment, it would be that it is so heavy when it is full of liquid, but I really am enjoying it and plan to order another. I really hope Swig will make this 40oz mug in the Bluebonnet pattern for this Texas gal!

Awesome and stylish!

This mega mug is wonderful! It has kept my drink chilled all day. It fits in the cup holder of my car which is a huge plus! The print is super cute and stylish. I’m already eyeing my next mega cup! The designs are so cute; I could own them all! I’m extremely impressed with this mug!

Love this cup, print and new size. Keeps me from filling my cup up so many times throughout the day!

Happy birthday to me!

Ordered the new 40oz Wanderlust Mega Mug Swig and I love it and the silicone straw! The color is even prettier in person and keeps my water at the perfect temperature! This is my second Swig and I’ll definitely be ordering more!
