Rolltop Backpack “Rhein” – Boat2Bag
Brand: Boat2Bag
Product Description: Looking for a bag with a story no one else has? The Boat2Bag Rolltop Backpack is crafted in Switzerland from upcycled boat tarpaulins taken from vessels on Lake Constance and the Rhine. These materials are built to endure weather, waves, and time — which makes them perfect for a backpack that works as hard as you do.
Water-resistant, structured, and incredibly durable, this rolltop design adapts to your day: commuting, travelling, or heading outdoors. And the best part? No two bags are ever the same. Each piece carries the marks, colours, and textures of the boat it once belonged to. When yours arrives, the exact tone and pattern will be a small, meaningful surprise — a one-of-a-kind accessory with history stitched into every seam.
Specifications:
• Made in Switzerland from upcycled boat tarpaulin
• Water-resistant and built for long-term use
• Adjustable rolltop closure for flexible capacity
• Fits a 15" laptop comfortably (size: ca. 60 x 37 cm)
• Padded straps for daily comfort
• Each bag is completely unique (colour + pattern vary)
Care Instructions: Wipe clean with a damp cloth. Avoid machine washing and prolonged sun exposure to preserve the character of the upcycled material.
🌿 Note: By choosing this bag, you support Swiss upcycling and give a second life to materials that would otherwise go to waste. A practical piece — and a conversation starter.

Secondhand & Vintage Sizing
Vintage and secondhand pieces do not always match today’s size standards. We list actual garment measurements (in cm) on each product page. Compare these to a similar item you own for the best fit.
How to Measure (quick guide)
Use a soft tape measure over lightweight clothing. Keep the tape parallel to the floor and snug, not tight. If you’re between sizes, we recommend referring to the brands' specific fit notes (above).
Bust (women)
Measure around the fullest part of your bust, keeping the tape level across your shoulder blades. Breathe normally; don’t pull the tape too tight.
Chest (men)
Measure around the fullest part of your chest, under the arms, keeping the tape straight across your back. Relax arms at your sides.
Waist
Measure at your natural waist (the narrowest point, usually above the navel). Keep the tape comfortably snug.
Hips
Stand with feet together. Measure around the fullest part of your hips/seat (typically 18–23 cm below the waist), keeping the tape level.
Inseam (pants)
Measure from the crotch seam down to the bottom of the leg. Tip: measure a pair of trousers that fits you well for the most accurate inseam.
Foot length (shoes)
Place your heel against a wall on paper. Mark the longest toe and measure from wall to mark. Check our shoe table and size up if between sizes.
