Packing a perfectly appointed workbag is walking on a razor’s edge. You need to be prepared but unencumbered. You need items that function. You need items that are convenient. You need stuff but you don’t want mass.

Your keys can’t do anything for you when you spill lunch on your new white shirt. Your wallet and phone can’t protect you from surprise showers. When you leave your house, make sure you have everything you’ll need for the day. Make the journey to work less miserable with these things to carry, organize, and optimize your day.

As a home base of sorts. Amazon

The Fisher 400B Space Bullet Space Pen is out of this world—and, in fact, can be taken out of this world. Write at any angle, in zero gravity, and at extreme temperatures. This pen is brass with a chrome finish and even exhibited in the Museum of Modern Art for its classic design. The ink cartridges are hermetically sealed, pressured with nitrogen gas, and made out of the same material used to make armor-piercing ammunition. Sign me up.

If you are stuck in the rain, let the force be with you. Not the force of the wind that is, but the force of this Star Wars lightsaber umbrella. The 32-inch umbrella is built with a double canopy and acrylic frame, which makes it extra sturdy and virtually rust-proof. The 14mm fiberglass shaft has a button on the bottom handle to switch on and off the light. Batteries not included (3 AAA needed).

If you don’t want to carry around a library, get an e-reader. I, admittedly, arrived pretty late to the Kindle game, but I’ve been using my roommates Kindle Oasis and I am now sold. Read classics that are in the public domain for free, or hit up your daily newspaper or that best seller you’ve been hearing about for months. The Kindle Oasis has 23 LEDs, an adaptive front light, and a battery that will last weeks on a single charge. Nothing beats the feeling of flipping through the pages of a real book, but this comes pretty close.

These fruit and veggie totes are made of a lightweight, durable nylon polyester that can be tossed in the washing machine. When squished into a ball, they only occupy 2-3 inches of space. You’ll barely notice they are there.

No one can slurp up an entire bowl of pasta without the noodle whipping around as it is sucked into your mouth splattering your shirt with that red goodness. Have a way to get stains out so you aren’t that office slob. Bring a Tide to Go pen. (And even if you’re not prone to spills, there’s nothing like being the office hero with a stain-removing pen.)

For people who forgot to juice up the night before. Amazon
