• This Basics 2Life Sleeve from MW Sleeves has been designed to perfectly fit the MacBook Air 15" (2023). From the zippers to the memory foam, to the inner and outer fabrics, this sleeve is made of 99 per cent recycled eco materials - with 12 water bottles used to produce each sleeve. Its shock-absorbing polyurethane memory foam reduces the risk of damage to your MacBook, while its ultra-soft inner lining protects your laptop from scratches.
