Why go to all that trouble?. 1 - it really protects my MacBook Pro from impacts: much much MUCH sturdier than neoprene. 2 - the zipper (and construction generally) is top quality: I had my previous identical sleeve for 4 years of heavy 24/7 use and never had any problem.
This subtly detailed, traditional sleeve provides a streamlined option that fits within anyone's comfort zone. The wrap construction cradles your laptop in substantial foam padding, and thoughtful details add hints of sophisticated styling.
