The Breathe Sleeve from BBP Bags is a neoprene sleeve for 13″, 15″, or 17″ laptops. The sleeves are made of 4mm-thick, 4-way stretch neoprene. The laptop compartment closes with a zipper, and there’s a front accessories pouch, a back slip-in pouch, and even a little pouch for a USB flash drive. What separates the Breathe Sleeve from other laptop sleeves is the BBP Breathe Technology that keeps your laptop cooler to prevent battery damage from heat. The sleeves fit 13″, 15″, or 17″ MacBook Pros and PCs (check the website for interior dimensions to determine if your PC will fit). The 17″ size is available only in black; the other two sizes are available in black, khaki (shown), fuchsia, and pink. All sizes are $34.95.
