Packable backpacks occupy a smart niche in everyday carry and travel gear—lightweight, compressible, and easy to stash until the moment they’re needed.

Whether heading out on an impromptu day hike or exploring a new city, the best examples serve as a reliable carry option without taking up prime real estate in your luggage.

If a packable backpack isn’t currently in your travel quiver, one of the more trusted options in this category—the Mystery Ranch In and Out 18L—is currently available at Huckberry in two colors as part of the retailer’s summer sale event, marked down to one of the lowest prices we’ve seen to date.

Simple, Functional Design

The bag includes two external sleeves with elastic drawstrings to hold water bottles, tripods, umbrellas, and more. There’s also a hydration reservoir pocket with hydration ports on lid.

The In and Out 18 is made from ROBIC rip‑stop nylon that’s light enough to roll into its own front pocket but tough enough to shrug off day‑to‑day wear.

YKK zippers and Duraflex hardware add reliability without drama.

There are no bold colors or loud tags here—just a clean, utilitarian silhouette that transitions from trailhead to café with minimal fuss.

This is an image of older version of the In and Out packed down into its front pocket. The current bag looks slightly different when packed down, but not in a meaningful way. It’s not the smallest packable backpack we’ve seen, but it still shrinks down to a highly portable form factor.

It doesn’t hold its shape like a structured daypack, but that’s part of the design. The In and Out adapts to whatever you put inside—whether it’s just a jacket and snacks or a fuller load like a DSLR and extra layers.

Packed light, it carries light. When packed heavy, it molds around the contents. For some, that flexibility is a plus. For others, it means being thoughtful about how much you carry.

The bottom line is that this pack carries far more than a typical 18L pack, mainly because nothing about the bag’s design prevents or blocks items from being stuffed inside.

Just Enough Utility

While a sternum strap can help balance the pack’s weight, the unstructured design of this pack means you’ll need to pack smartly to maximize carrying comfort on longer treks.

Dual water-bottle sleeves with elasticized tops, external tool attachment loops, and a hydration-reservoir-compatible sleeve are modest but thoughtful additions.

Comfort-wise, lightweight padded straps with mesh and a simple sternum clip keep it secure at a minimal weight penalty. There’s no back-panel padding—so proper packing is key.

“It’s an awesome travel‑friendly day pack I’ve used everywhere from here to the Himalayas.”

Our managing editor has to say this about the In and Out as a total package.

“I’m personally a huge fan of the in and out. It’s an awesome travel‑friendly day pack I’ve used everywhere from here to the Himalayas.”

A Very Compelling Price

Here’s where the value narrative gets stronger: Huckberry currently has two colors of the In and Out 18 on sale at what appears to be the lowest price we can remember.

If a light, dependable pack is on your radar, now is the moment.
