    I miss the old envelope design

    Fits my Cadet perfectly, further extending the life of an excellent bag.

    Only wish it used to old envelope-flap design, which I found SO MUCH EASIER to get the computer in to and out of.

    Zippers make sense for some people, but not especially for me. Ahh, well.

    (please excuse cat hair in picture - my old Cache has become a favorite perch)

    Nice, but doesn't fit MacBook Air so well

    Nice sleeve, and good quality, but it's a little too big for the 2022 MacBook Air--even though it says it's compatible.

    Suspension for your tech

    This cache fits perfectly and I love it. I have three of them for my 12.9" iPad Pro, 13" MacBook Pro with Touchbar, and 14" M1 MacBook Pro. The cache itself is padded and provides a tight, but perfect, fit for each device. The straps allow for a clip in to my Cadet and allow for easy access while securing it in the bad for travel. I would buy one of these for any device I planned to travel with.

    Sigh there where more sizes!!!

    Had to go with the bigger cache to protect my iPad mini. Love the quality and craftsmanship, it just takes up more room in my bag than it needs to.
