TLDR: The SIV is our bestselling crossbody: 17 litres of space in a clean moon-bag shape, a zipped main compartment, water-repellent nylon, and a wide, adjustable strap that stays comfortable all day.
SIV
Ordinary tote bag
Backpack
A regular tote slides off your shoulder the moment you move. The SIV's crossbody strap sits across your body and stays put, walking, cycling, or carrying groceries. Our customers voted it the #1 feature of the bag.
The SIV holds a full day: laptop, sweater, water bottle, chargers, even a gym kit or an overnight change. 17 litres in a bag that still sits flat against your body.
Exactly what i wanted, a sling bag that could carry my working laptop, notes, headphones and so on. Becoming a father in 1 month, so i think the extra space will come in handy.
The main compartment closes with a full zipper. Nothing falls out on the bike, nothing gets grabbed on a busy tram, and everything stays where you put it.
The SIV is made of water-repellent light nylon. Light rain, a spilled drink, a wet bike ride, it shrugs it off and stays light on your shoulder.
The SIV bag is very practical. It basically fits everything I need when I go for a walk, to work, or to meet friends. The workmanship is very solid. A big advantage is that it is waterproof. I definitely recommend it!
Keys, phone and wallet get their own spots, with a zipped pocket for the things you really don't want to lose. Reach in, grab, done, no digging.
Good quality, perfect fit. Love the compartments inside. Great that I’m able to sling over like a messenger bag. Love the colour too.
A minimal moon-bag silhouette, worn at your side. Clean colours, no logos, no straps flapping, it fits your outfit whether you're heading to work, dinner or the weekend.
The beige SIV bag that I bought is actually a really nice bag! It fits all my university essentials (and then some), and keeps me from having a sweaty ass back in warm weather like wearing a backpack does, and it's actually quite comfortable to wear too!

Best Sling bag ive ever purchased.
Really well made, easy to sling over my head for the cross body, hands free. And capacious. Am going to try it on a flight, not just the weekend grocery/markets shopping. Delivery was fast and efficient.
Absolutely love the black SIV bag, it’s the best bag I’ve ever bought!!
I recently picked up the SIV, and it strikes a great balance between practicality and understated style. The material is durable yet lightweight, and the compartments inside are thoughtfully laid out.
You get a 30-day home trial. Wear it for your normal week (commute, work, groceries, gym) and if it's not for you, returns are easy.
17 litres: laptop, sweater, water bottle, chargers, even an extra pair of shoes or a gym kit. Dimensions: 60 x 36 x 10 cm.
Yes, up to 100 cm, and it's 5 cm wide so it spreads the weight instead of cutting into your shoulder. Wear it high, low, or anywhere in between.
Yes. The SIV is made of water-repellent light nylon that handles light rain and everyday spills. It's not made for soaking or machine-washing, a soft damp cloth keeps it clean.
