Even though it’s called a sleeve, we’d describe Brenthaven’s Collins Sleeve Plus ($60) as a small bag, optimal for carrying around your MacBook, iPad, and a few other small accessories. The heather gray exterior is nice enough that it could be used in a semi-professional setting, but casual enough that you won’t feel out of place carrying it around elsewhere. It’s slim, too: only 16 inches wide, 12.5 tall, and two inches deep.
Under Collins Sleeve Plus’ top flap, you’ll find a padded pocket for your 11”, 13”, or 15” MacBook Air or Pro, plus another in front of it for an iPad. There’s a third pocket for accessories in front of the other two. The nylon shoulder strap is permanently attached, meaning you can’t use the sleeve as just a sleeve, but we’re okay with that: the strap is the sort of “plus” that justifies this case’s name.
