STREAM Sling Bag: across your chest or round your waist, 3 waterproof litres to hand.

The STREAM Sling Bag is a 3-litre waterproof Sandqvist bum bag in PU-coated recycled polyester, weighing 340 g. You wear it across your chest all day: phone and keys in the zipped front pocket, wallet in the big inner pocket. When it's lightly loaded, two straps at the sides pull it flat against you.

Light rain

Water-resistant fabric

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

Proper rain

PU-coated recycled polyester and YKK Aquaguard zips: your phone and wallet stay 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 bum bag you can wear all day: padded back, straps to flatten it, and 3 litres for the essentials.
Worth knowing: 3 litres, for the essentials: a jumper or jacket won't fit.
Who it's for: Anyone who wants their hands free all day, in town or on a walk, and the essentials dry when it rains.

Baptiste, Eiken

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.
