I just got another Retina MB (base model in Space Gray). I carry it around a lot and it feels like I'm carrying around too much to carry it in my Timbuk2 bag so I started looking for sleeves. I still use the Timbuk2 bag when I need to carry accessories but going to meetings and when I know I won't need accessories I'm going to use a sleeve. I bought this one on Amazon to get me by until I could research a bit more. It's nice for the price and gets the job done. It's very unassuming and most people that have asked me about it thought it was just a paper notepad. http://www.amazon.com/gp/product/B00X9NBDVA?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00 After doing quite a bit of research I ordered a Joli Sleeve. It is expensive but it sure looks nice. I ordered the Smooth Gray with Red liner. It was just over $100 US including shipping. I have no affiliation with Joli but I've read nothing but good things about them. They are based in Amsterdam and are a small company and even include a handwritten note to each customer. A nice little added personal touch. I'll be sure to post updates when it comes in. I can't wait! https://jolioriginals.com/products/smooth-macbook Is anyone else using a sleeve? If so, which one and how do you like it?
