Patagonia · Atom Sling 8L
Atom Sling 8L: the Patagonia sling bag worn across your back, on the bike, in hiking boots or running for the bus.
The Atom Sling 8L is an 8-litre Patagonia sling bag: a bag worn across the body, on your back, that stays close to you. On Saturday morning, from the market to the bike and on to the trail, you don't take it off: its wide, asymmetric strap keeps the weight close to your body, and the small zipped pocket on the strap keeps your phone to hand.
City · Cycling · Walks
Phone on your chest, jacket under the straps.

Across the body
The bag against your back, the pocket on your chest.








Colours
Five colours, worn, from sand to burgundy.
Weathered Stone
A pale sand with blue-grey buckles: light and crisp on a black T-shirt.
Cover Green
A soft eau-de-nil with a fir-green strap: gentle on an ecru fleece.
Smolder Blue
A slate grey with a midnight-blue strap: discreet on a light shirt.
Berry Fig
A ripe-fig burgundy with a lilac logo: the one that gets noticed.
Black
All black, buckles included: it disappears on dark clothing.
Blue Sage, also on sale, doesn't have a worn photo yet.

What fits inside
8L
The essentials, and one more layer under the straps.
The zipped main compartment has an inside divider. The front pocket holds your phone. On the front, two stowable straps hold a yoga mat or a jacket, and tuck away when you don't need them.
- The phone in the front pocket
- Small things in the strap pocket
- A jacket or a yoga mat under the straps
In the rain
Light rain on the bike is fine.
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
- Worn snug against your back, it doesn't swing about like a messenger bag: you can cycle, walk and run for a bus with it.
- Worth knowing
- 8 litres and 7.6 cm deep: no room for a laptop, and loaded all day, one shoulder carries everything.
- Who it's for
- People who get about by bike or on foot and want their phone, keys and a jacket on them, nothing more.

Questions
What are the dimensions and weight of the Atom Sling 8L?
34.3 × 22.9 × 7.6 cm (height, width, depth) and 340 g empty. There's no laptop or tablet pocket.
Is the Atom Sling 8L 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 Sling 8L fit in the cabin on easyJet, Ryanair or Air France?
Yes, and even as the free under-seat bag: 34.3 × 22.9 × 7.6 cm fits within Ryanair's 40 × 30 × 20 cm, Air France's 40 × 30 × 15 cm and easyJet's 45 × 36 × 20 cm. Size limits checked in October 2026: check with your airline before you fly.
Doesn't the Atom Sling 8L swing about and drag on your shoulder?
The wide, asymmetric strap keeps the weight close to your body: the bag stays snug against your back, even on the bike. But one shoulder carries everything; for a loaded day with a laptop, the Atom Tote Pack 20L goes on both.
