Patagonia · Atom Tote Pack 20L

Atom Tote Pack 20L: a small Patagonia backpack, laptop included, from the morning bike ride to the trail.

The Atom Tote Pack 20L is a 20-litre Patagonia backpack with a smaller cut and a removable laptop sleeve. With a 43 cm back length, it suits a shorter torso, or anyone who simply wants a less bulky pack. At 8.30 am, the sleeve and its cables head to the office; at 6 pm, the water bottle goes back in its side pocket and the bike light clips on underneath.

Laptop

A 13-inch laptop, and the sleeve comes out with it.

The padded sleeve comes out of the pack; its zipped pocket holds pens, cables and small office things, so you can go from work to the rest of the day without emptying everything.

13-inch

Removable padded sleeve, for laptops up to 13 inches.

Will it fit?

43 cm

back length, the “Atom Fit”

The “Atom Fit”: a 43 cm (17-inch) back length, for a shorter torso, or simply for a smaller pack. The Refugio, for its part, is cut at 48 cm, for most adults.

Measure your back before you choose.

Measure your back from your C7 vertebra (the bony bump at the base of your neck) down your spine to the top of your hip bones, and compare with the length shown.

Too short or too long? You have 30 days to send it back.

In the rain

Light rain, from the bike to the office.

Light rain

Water-repellent fabric

PU coating and a durable water repellent (DWR) finish: water beads up, then eventually gets through at the seams and zips.

This bag

Shower

Laminated fabric

Fabric covered with a TPU film (a flexible plastic) that stands up to the weather. The seams aren't taped.

Proper rain

Rain cover

A removable cover goes over the whole bag. Without it, the coated fabric eventually lets water through.

For a full day in the rain, use a rain cover or a dry bag inside: it isn't waterproof.

Eiken's take

Why we chose it
An office backpack scaled to a shorter torso: the 13-inch sleeve, the water bottles and the hydration reservoir, without the bulk of a Refugio.
Worth knowing
12.7 cm deep, the slimmest of the Atom backpacks: the sleeve takes a 13-inch, no bigger. For a 15-inch, the Refugio series.
Who it's for
People with a shorter torso, or anyone who wants a smaller everyday pack, laptop included.

Baptiste, Eiken

Questions

What are the dimensions and weight of the Atom Tote Pack 20L?

40.6 × 30.5 × 12.7 cm (height, width, depth) and 645 g empty, with a removable sleeve for a 13-inch laptop.

Is the Atom Tote Pack 20L waterproof?

It's water-repellent, not waterproof: the coated, treated fabric makes light rain bead up. For a full day in the rain, take a rain cover.

Does the Atom Tote Pack 20L fit in the cabin on easyJet, Ryanair or Air France?

As a cabin bag, yes, everywhere: 40.6 × 30.5 × 12.7 cm fits within Ryanair's 55 × 40 × 20 cm (Priority), Air France's 55 × 35 × 25 cm and easyJet's 56 × 45 × 25 cm. As the free under-seat bag, it fits on easyJet (45 × 36 × 20 cm); on Ryanair (40 × 30 × 20 cm) and Air France (40 × 30 × 15 cm), it's 6 mm too tall and 5 mm too wide. Size limits checked in October 2026: check with your airline before you fly.

Will the Atom Tote Pack 20L fit me if I have a long back?

Its 43 cm back length is made for a shorter torso, or for anyone who simply wants a smaller pack. For an average back length, the Refugio Daypack 26L is cut at 48 cm.
