A Rather Useful Backpack for Life’s Unexpected Weather

Imagine waltzing into a light downpour with all the poise of someone in a rom-com montage. Between balancing your coffee, dodging puddles, and remembering where you parked the bike, at least your backpack can be trusted to carry on carrying on. Blissfully waterproof, marvellously adjustable, and surprisingly handsome, this bit of kit is your daily drama’s most reliable supporting role.

Why Choose Our Waterproof Backpack?

Secure Pockets: Three zipped compartments keep everything in place, from laptops to leftover pastries of questionable vintage.
Flexible Shape: Clever roll-top design expands or cinches depending on whether you packed wisely or went wild at the market.
Hidden Storage: A discreet interior pouch for valuables, plus an exterior bottle holder for hydration within arm’s reach.
All-Day Comfort: Padded, adjustable straps offer relief to shoulders everywhere, so you can saunter hands-free and drama-free.
Rain-Ready Fabric: Water-resistant material keeps your belongings dry, even when the heavens mistake your commute for performance art.
Travel-Friendly: Folds away neatly, ideal for spontaneous getaways or last-minute dashes to somewhere vaguely interesting.

THE RATHER IMPORTANT BITS

This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.

SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.

Some are brilliant at international shipping, others prefer to keep things closer to home.

At checkout, you'll see exactly where this particular brand can send your goodies.

We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!

RETURNS

You have 14 days to return items.

Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!

🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.

Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!

We're frightfully modern and accept all the usual suspects:

Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay

SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!

All prices in lovely British pounds £ GBP, though international chaps will see converted prices.

We are Sostter

We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.

We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.

Sostter partners with independent brands that intrigue, inspire, and bring something genuinely different to the world of fashion, design, and living. Join us!
