If you're an avid yoga or Pilates girl, and you want a quality mat that's good for the earth and light on your purse then check out Lotuspad mats ($40). They're made of 100-percent biodegradable TPE (Thermoplastic Elastomer), and even though this mat is 5 millimeters thick, when it's all rolled up, it feels really lightweight so it's easy to carry. It resists bacterial and fungal growth and is reversible, so you can use both sides. They come in three colors: earth brown/forest green, fuchsia/lotus pink, and deep ocean blue/soft blue.
If that wasn't enough, they also make these adorable and unique mat straps. The part that wraps around your mat is made with adjustable velcro, so you'll get a snug fit to keep your mat from unraveling. Lotuspad is running a deal right now where you can get a mat and strap for $49. I have the turquoise and brown-dot strap, but click on the pictures below to see the other cheery choices.
