STREAM Sling Bag
STREAM Sling Bag – Fully Rainproof Urban Carry for Every Condition (340 g)
Grey sky at 7am, rain by lunchtime, downpour by evening. Some days the city doesn't play fair. The Sandqvist STREAM Sling Bag was built for exactly that — a fully rainproof everyday carry that keeps your belongings safe without asking you to plan around the weather. At 340 g and 10.5L, it's compact, clean and completely dependable.
Unlike water-resistant bags that hold up in a drizzle, the STREAM Sling goes further: recycled polyester with a full waterproof PU coating, combined with Aquaguard YKK zippers — the waterproof zipper standard used in serious outdoor and sailing gear. Everything inside stays dry. Not just surface-repellent: actually dry.
Its quilted, ventilated back panel and adjustable side straps make it as comfortable to wear for a full day as it is reliable in a downpour. Wear it crossbody for commuting, swing it to the waist for tighter situations. Fully vegan, built from recycled materials — and designed to last through every season.
What Makes the Real Difference in Any Weather
The STREAM Sling isn't just resistant to rain — it's built to ignore it. Every material choice and construction detail points toward one thing: your belongings stay dry, whatever happens above you.
- 🌧️ Fully waterproof – PU-coated recycled polyester + Aquaguard YKK zippers, not just a DWR spray.
- 🔄 Adjustable side straps – slim down for light loads, expand for more gear.
- 🌬️ Quilted ventilated back panel – breathable comfort for all-day wear.
- 🔓 Double-zipper main compartment – full access from both ends.
- ⚡ External zip pocket – phone, keys and transit card within instant reach.
- 🔒 Large internal zip pocket – valuables secure and separate from the main load.
- 🪶 340 g – barely there on the body, all day long.
The adjustable shoulder strap (max 120 cm) lets you dial in the fit for crossbody or waist carry. Switch modes mid-day as your situation changes — both keep the bag stable, close to the body and completely within reach.
Who This Bag Is For
The STREAM Sling is for anyone who's tired of checking the forecast before choosing a bag. It's the carry for city commuters, cyclists, travellers and day-trippers who want real weather protection without compromising on weight or aesthetics.
- You live in a rainy city — or simply don't want to think about weather.
- You commute by bike or on foot — and need a bag that handles real exposure.
- You want compact and hands-free — without the bulk of a backpack.
- Sustainability matters to you — recycled materials throughout, fully vegan.
If your daily carry requires a laptop or a larger volume, the STREAM Zipper Backpack 16" offers the same waterproof protection in a bigger format. But for a compact, fully weatherproof sling that handles everything from the morning commute to a weekend market in the rain, the STREAM Sling is the bag you'll reach for first.

FAQ
Two things work together: the fabric uses a full waterproof PU coating — not just a surface DWR spray that washes off over time — and the zippers are Aquaguard YKK, the same waterproof zipper standard used in technical outdoor and sailing gear. Water cannot enter through the fabric or the closures. It's built for sustained rain, not just dampness.
Crossbody is the most versatile and comfortable for most people — bag sits at hip level or across the chest, stable on the move. Waist carry is ideal for cycling, running errands or when you want the bag completely out of the way. The strap (max 120 cm) adjusts easily between both modes in seconds. Both keep the bag secure and hands-free.
For a focused day carry, yes: phone, wallet, keys, small water bottle, headphones, a light jacket and a snack all fit comfortably. The adjustable side straps help compress or expand the bag's depth to match your exact load. For heavier days — laptop, gym kit, full day out — the STREAM Zipper Backpack 16" provides more volume with the same waterproof protection.
The side straps run along the depth of the bag and tighten or loosen to control how much the bag expands outward. Tighten them for a slimmer, more streamlined profile when carrying less. Loosen them to increase depth for a larger load. It's a fast, one-motion adjustment that works without opening the bag — useful when your load changes mid-day.
Three zones: the main compartment (double zipper, full-depth access) for your primary load; a large internal zip pocket for valuables like a passport, cards or cash; and a front external zip pocket for instant-access items — phone, transit card, keys or earbuds. Clean, logical, intuitive to use on the move.
Yes. The quilted ventilated back panel reduces heat buildup and pressure against your body — a meaningful upgrade over flat-backed sling bags. The lightweight build (340 g) means it never becomes a burden over a long day. Alternating between crossbody and waist carry also helps redistribute the load when needed.
The smooth waterproof surface wipes clean easily with a damp cloth — one of the practical benefits of the PU coating. For deeper cleaning, hand wash with mild soap and cold water then air dry fully. Avoid machine washing, tumble drying, bleach and ironing, which degrade the waterproof coating over time.
