Sandqvist · STREAM Messenger Bag

STREAM Messenger Bag: chest strap buckled, it stays on your back on the bike.

The STREAM Messenger Bag is a 15-litre waterproof Sandqvist messenger bag in PU-coated recycled polyester, weighing 500 g. In the morning, you swing it onto your back, buckle the chest strap, and it stays put all the way to the office. The 16-inch laptop travels inside, under a flap closed by two buckles.

Laptop

The 16-inch has its own pocket, held by a press-stud tab.

Under the flap, a 44 × 28 cm pocket takes the 16-inch laptop, and a press-stud tab holds it in place when you open the bag. In the main compartment, a zipped pocket keeps the charger and small things.

In the rain

A downpour on the cycle lane: the waterproof fabric keeps it out.

Light rain

Water-resistant fabric

Light rain and road spray run off it; in steady rain, water eventually gets through.

Proper rain

Waterproof fabric

PU-coated recycled polyester and YKK Aquaguard zips, flap pocket included: the laptop stays dry in steady rain.

This bag

Waterproof in the rain, not made to be submerged.

Sandqvist

Bags for the city and for the forest, designed in Stockholm since 2004.

Since 2004

Three childhood friends, Anton, Daniel and Sebastian, founded Sandqvist in Stockholm: they split their time between the city and the forest and couldn't find a bag made for both.

Carried before it's sold

Every prototype is carried by bike around Stockholm, on trains and planes and along forest paths before it makes the collection.

2-year guarantee

Sandqvist guarantees its bags for two years against manufacturing defects: zips, buckles, seams. For a bag bought from Eiken, the claim goes through us.

Eiken's take

Why we chose it: A waterproof messenger that stays on your back on the bike: chest strap, shoulder strap on the left or right, and room for a 16-inch.
Worth knowing: 15 litres, flat: a day at the office, not your gym kit as well. To take everything, the STREAM Rolltop Backpack L goes up to 34 litres.
Who it's for: Anyone who cycles to work and would rather have a messenger bag than a backpack, even in the rain.

Baptiste, Eiken

Questions

What are the dimensions and weight of the STREAM Messenger?

28 × 44 × 12 cm (height, width, depth) and 500 g empty, for 15 litres. The laptop pocket measures 44 × 28 cm.

Is the STREAM Messenger waterproof?

Yes, it's waterproof: with PU-coated recycled polyester and YKK Aquaguard waterproof zips, it keeps your things dry in the rain. It's made for rain, not for being submerged.

STREAM Messenger or STREAM Zipper Backpack 16"?

The Messenger is a messenger bag: 15 litres, 500 g, 12 cm deep, a chest strap, and the laptop under the flap. The Zipper Backpack 16" is a 23-litre backpack weighing 720 g that opens with a zip, with the laptop coming out at the top. Both are waterproof and take a 16-inch.

Does the STREAM Messenger fit under the seat on a plane?

On easyJet, yes: at 28 × 44 × 12 cm, it fits the 45 × 36 × 20 cm free small bag. On Ryanair (40 × 30 × 20 cm), no: its 44 cm width is too much, so it goes as a cabin bag (55 × 40 × 20 cm). Size limits checked in October 2026: check with your airline.
