If you want to crush your shoulder, and at the same time have all your gear and gadgets within easy reach, then a messenger bag is the way to go. Less formal than a briefcase, and less sporty than a backpack, a messenger bag is stylish and practical. And Pad & Quill’s Attache messenger bag is more stylish and practical than most. It’s a hand-stitched leather beauty which can swallow most of your Mac and iOS devices and accessories.

TwelveSouth’s Bookbook Caddysack might sound like the babble of a sugared-up two-year-old, but it is in fact a super-handy gadget bag for travelers, or folks who spend a lot of time not at home or the office. It’s a little case that’s designed to hold all the chargers and other accessories you need for your various Apple devices.

My closet floor resembles a bullpen. But instead of pitchers, it houses a rotation of backpacks and bags ready to be activated for work, day-long excursions or extended travel. Depending on the week, I could shift between four or five bags.

But when Shift Pack recently arrived for a tryout, it threatened to retire a couple of my veterans. It is a single backpack that aims to cover all the bases, work, play and travel or all at once if necessary.

The Kings laptop backpack by STM Goods is handsome enough, but one small detail on the inside got my attention.

Tethered inside one of the two compartments I found a zippered pouch that could be used to store pens or cords. I stow my various incidentals in similar pouches in my shoulder bag, so it seemed like this particular backpack was designed especially for me.

BERKELEY, Calif. — ILE is big in Japan. The California bag company has found a market with the Japanese bike website Blue Lug, and the collaboration keeps pushing ILE into new bags, materials, hardware and color choices.

Eric Fischer, 26, launched ILE (short for “Inside Line Equipment”) out of his apartment four short years ago. He was racing bikes, buying fabric and making bags one at a time for himself, his friends and friends of friends.

“I always liked making things, but building buildings didn’t seem scalable,” Fischer told Cult of Mac. “Making bags seemed more like a painting rather than building a house.”

SAN FRANCISCO — Twenty-five years ago, a bike messenger sat in his garage and used an old-school Singer sewing machine to stitch his mark on the world.

That bike messenger was Rob Honeycutt, and the bags he made in 1989 were called Scumbags. They were designed for use by the city’s notorious two-wheeled delivery riders, whose fashion sense tended toward crude cutoffs, T-shirts and hoodies.

A year later, Honeycutt changed his operation’s name to Timbuk2, and the company’s been crafting an increasingly ambitious line of bags ever since, expanding far beyond the world of tattooed dudes on fixies.

“Timbuk2 wasn’t going to the office 25 years ago,” CEO Patti Cazzato told Cult of Mac during a recent tour of the company’s Mission district factory, where all of Timbuk2’s custom bags are made.

I was pretty sure I would never need to look any further than my trusty Chrome bag when it came time to be out and about with my electronics. It was a simple system, really: Just chuck everything into the bag’s cavernous pocket, buckle it in and go. It was quick, and it worked — until I needed to actually get anything out of there.

See, for all its style and the novelty of its seat-belt strap, Chromes are really only meant to transport one or two larger packages. Because they’re messenger bags. You know, for messengers.

The MixBag takes a different approach: It’s smaller, but it has a pocket for everything you might possibly need to carry around.
