Are there heavier made snuggies for colder climates?

You might want to try something out like this! I like the idea that it comes in some nicer colors like red, green, blue & gray. It also looks like a throw when you are not using it. ; ) Looks like they are on sale at $28.98 regular $57.00

Made of the most comfortable fleece technology, the Ultimate Slanket is thick yet remarkably lightweight--and machine washable, too. It's generously sized to be the perfect fit for just about everybody.

Especially those that want to read a book, channel surf, work on a laptop, eat popcorn, play video games, and more, all while staying completely cozied up. You could even consider taking it along for extra warmth at the big game, or for fun camping trips with your family. And, when you're not wearing it, the Slanket looks like a stylish throw draped over your couch, chair, or bed.
