A Rather Marvellous Bag for Practically Everything
Ever wished your bag could keep up with your wildly unpredictable (yet thoroughly fabulous) day? Well, here's your answer. This multifunctional 3 in 1 bag gives you the confidence of a finely tuned butler who just so happens to transform into a sherpa, personal assistant, and style consultant without so much as a raised eyebrow.
Why Choose Our Multifunctional 3 in 1 Bag?
Three Ways to Wear It: Whether you're feeling casually on-the-go, subtly stylish, or dashingly prepared, this bag shifts from backpack to shoulder bag to handbag faster than you can say "last-minute meeting at the café".
Roomy Yet Respectable: Cleverly padded to fit laptops up to 17 inches (honestly, that's quite a bit of laptop), plus compartments for tablets, snacks, emotional support notebooks—whatever tickles your fancy.
Built for British Weather (or Worse): Made of durable waterproof Cordura with gentle padding on the back and bottom, it firmly resists surprise downpours and sudden curb encounters alike.
Product Details:
- Dimensions: 14 x 26 x 44 cm
- Capacity: 14 liters
- Material: Waterproof Cordura
- Handmade In: Tartu, Estonia
Rather good, isn’t it? Especially knowing it’s crafted by the same experienced hands trusted by mountaineers. Except now it’s rescuing your daily routine instead of braving the Baltic peaks. Snap one up before they inevitably fall into the hands of everyone else with impeccable taste.
SHIPPING + RETURNS
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!
PAYMENT
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.
Any payment pickle? We're here to help sort things out! Contact us

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.
Giving Back
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.
