Bubble Bags Lite NEW! Fresh Headies introduces a more cost-effective line of Bubble Bags, same top quality, but in a lighter fabric for the budget conscious home user. These bags use a medical grade, German made screen fabric for top quality extraction, only slightly less robust than our regular Bubble Bags. We were able to cut costs by manufacturing the nylon side walls with some variation in colour and weight, removing the draw string, and going with a more economical carry bag.
