RadTech's Sleevz are definitely rad. It's no wonder why we featured the Sleevz as one of the best forms of protecting your MacBook in the most non-bulky way guide. The RadTech Sleevz are made from RadTech's Optex fabric material and it's super thin. When I say super thin, I mean literally super thin. It's the most amazingly thin sleeve I've ever tried and I love everything about it. We've got RadTech's Limited Edition Ultra-Violet colored Sleevz so be sure to check out the full review right after the break.
