Stella McCartney has done it again with another fabulous design collaboration, this time with LeSportsac. Her past work has been done with the high fashion label Chloe and also with athletic wear company Adidas.

McCartney is now designing bags for LeSportsac that will be made entirely out of "green" materials, as she always does because she is a die-hard PETA supporter and a vegetarian. All of her "green" bags will be made of non-leather goods and fabrics that are 100% biodegradable.

The adorable Bunny Backpack (pictured) is part of the new collection but if adorable animals aren't for you the collection also has plenty of practical bags as well. With each piece from the collection you can choose from a variety of fabrics to customize the bag, all from the comfort of your laptop.

I may be a woman in my twenties ... late twenties (head hanging in shame) but I really want this bag for myself. But I have a good feeling that these bags will sell fast as they have already been featured in publications like Teen Vogue.
