The turtles, it turns out, got it right: They take everything with them wherever they go.

Unfortunately, air travel restrictions being what they are right now, you can’t even carry on a liter of water.

But there are ways to survive the flight, as long as you pack the right things into your 14-by-21-inch trunk.

Start by picking the right trunk. Blibetroy’s soft leather Breit bag fits everything for a quick weekend jaunt. And hey, it’s reversible, so when you’re sick of brown, switch to light turquoise. Heading to warmer climes? Not without Hayden-Harnett’s cheery, sunny Erol canvas tote.

Now you have to get there. (On that icky, icky plane.) Protect yourself from in-flight cooties by wrapping your seat in a PlaneSheet. Okay, we’d never have the guts to go that public with our OCD, but it’s a great idea — as is the Cabin Cuddler, a travel blanket with a pocket for your feet.

A much more discreet way to ward off germs: Slather By142 Skin Fortifier on face and hands — it’s a lightweight, protective barrier between you and the dirty world. Or get the carry-everywhere, under-$2 version, CVS Hand Sanitizer.

You’re there. And the hotel room reeks. Unpack Anthousa Chinoiserie scented sticks and revel in winter daphne and peony bliss. (Plus, your suitcase will smell great, too.)

It’s a little uber-geek, but Tumi’s Ultra Slim Universal Power Adaptor can attach anything to anything. What to charge? A cool GSM phone and an insane camera.

Now get out there and explore your world.

The turtles wouldn’t want you to hide in your shell.
