The Bag That Does Rather More Than You'd Expect
Imagine a bag that transforms from sophisticated tote to practical backpack without the faffing about. Our convertible design has already charmed the judges at the Etsy Design Awards, and we suspect it'll rather charm you too. Perfect for work, travel, or the sort of person who can never quite decide what they need until they've already left the house.
Why Choose Our Convertible Backpack Tote
Two Bags, One Purchase: Wear it as an oversize tote when you're feeling proper and put together, or tuck the straps behind the back panel to go hands-free when life gets properly hectic.
Room for Everything: Fit your 14 inch laptop, a change of clothing, several books, and all the bits you've forgotten you've collected. The main compartment is genuinely roomy without being absurdly unwieldy.
Beautifully Made from Ethical Materials: Organic cotton certified by the Global Organic Textile Standard paired with supple vegan leather free of PVC. Wood trims add a touch that feels rather good and altogether guilt-free.
Five Thoughtfully Placed Pockets: A zippered pocket for your phone and valuables, mini pockets for sunglasses and keys, and a back pocket specifically for your Metro card. Honestly, it's the little things.
Trolley Sleeve Design: Slip it over your suitcase handle for seamless travel without breaking stride.
Product Details
Dimensions: 17 inches high by 14.5 inches wide by 4.5 inches deep. When folded over as a tote, it sits at 14 inches high. Handle drop measures 8.5 inches.
Laptop Capacity: Fits laptops ideally 14 inches or smaller, allowing the top to fold over properly.
Materials: Organic cotton and eco-friendly dyes certified by Global Organic Textile Standard, supple vegan leather free of PVC, and wood trims.
This rather marvellous bag has become our most beloved style for good reason. It's the sort of thing people ask you about on the train, which is always slightly embarrassing but rather nice.
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!
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 Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
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.
