STREAM Zipper Backpack 16" – The Rainproof Urban Backpack for Daily Commuters (720 g)

Rain mid-commute. Unexpected downpour at the station. Laptop in the bag. The Sandqvist STREAM Zipper Backpack 16" was designed for exactly this — a fully waterproof urban backpack that keeps your 16" laptop and everything around it completely dry, all day, in any weather. No compromise on protection, no compromise on the carry.

Its distinctive turtle-shell silhouette pairs a vertical front compartment with a top-access main compartment, creating a logical organisation system that's intuitive in motion. The separate padded 16" laptop compartment opens from the top independently — in and out at security or at your desk without unpacking everything else. Two external side pockets keep a bottle or quick-access item within reach at all times.

Built from recycled polyester with full waterproof PU coating and Aquaguard YKK waterproof zippers throughout, the STREAM Backpack is as durable as it is weatherproof. The wave-quilted ventilated back panel and padded shoulder straps with gear loops make it a genuinely comfortable backpack for long days on the move — not just a waterproof box you strap to your back.

What Makes the Real Difference in Any Weather

The STREAM Zipper Backpack doesn't treat waterproofing as an afterthought. Every detail is built around keeping your gear dry — while still delivering the organisation, comfort and practicality of a premium urban daily carry.

🌧️ Fully waterproof – PU-coated recycled polyester + Aquaguard YKK zippers throughout.
💻 Padded 16" laptop compartment – separate top access, no need to unpack the main bag.
📂 Vertical front compartment – full visibility and fast access to documents and layers.
🍶 Two external side pockets – water bottle, umbrella or quick-access items.
🔗 Gear loops on shoulder straps – attach a light, carabiner or bottle clip.
🌬️ Wave-quilted ventilated back panel – airflow and comfort for long days.
♻️ All recycled materials – polyester, polyethylene foam and nylon webbing.

The padded adjustable shoulder straps and sternum strap compatibility (attachment points provided) let you tune the carry for your body and load — balanced and close for a long commute, looser for quick access throughout the day. At 23L, it's genuinely capable without ever feeling oversized.

Who This Backpack Is For

The STREAM Zipper Backpack is for urban commuters who refuse to compromise — those who need real laptop protection, practical organisation and reliable waterproofing in a bag that looks at home in the city.

You commute daily with a 16" laptop — and want it genuinely protected from rain.
You move in all weather — by bike, on foot, at all hours of the day.
You're tired of "water-resistant" failing when it matters — you want actually waterproof.
You value smart organisation — vertical front pocket, separate laptop access, side bottles.
Sustainability is non-negotiable — recycled materials throughout, fully vegan.

If ultra-lightweight carry is your absolute priority and you work in a dry environment, a lighter bag may suit you. But for a reliable, fully weatherproof daily backpack that carries your laptop safely and adapts to urban life season after season, the STREAM Zipper Backpack 16" delivers exactly where it counts.

FAQ

Is the waterproofing reliable for heavy, sustained rain?

Yes. The full PU waterproof coating on the recycled polyester fabric and Aquaguard YKK waterproof coil zippers throughout provide robust protection in heavy rain — not just a surface treatment that degrades after a season. The construction is built for long-term, reliable waterproofing in real conditions.

How does the vertical front compartment work?

The front compartment opens vertically downward like a book, giving you full visibility of everything inside in one glance. It's secured by a waterproof zipper and held by a 15 cm high gusset when open to prevent items from falling out. Ideal for documents, a light jacket, a padded sleeve or anything you need to access quickly without going into the main compartment.

How does the separate laptop access work?

The padded 16" laptop compartment opens separately from the top via its own zipper — fully independent from the main compartment. Pull your laptop out at airport security or at your desk without opening or unpacking anything else. The padding protects against bumps and pressure during transit.

Is 23L enough for work, travel or weekend trips?

23L is the ideal volume for a full daily commute (laptop, change of clothes, lunch, gym gear, accessories) and handles a 1–2 night trip as carry-on luggage. For extended travel or hiking, a 30L+ pack gives more autonomy. For urban use, 23L is the right size — not too much, not too little.

What are the gear loops on the shoulder straps for?

The loops sewn into the shoulder straps let you clip or attach external items — a carabiner, a small flashlight, a bottle clip or any lightweight accessory. A detail borrowed from outdoor and cycling gear that adds genuine utility to a daily commuter pack without adding weight or visual bulk.

Can I add a chest strap?

The backpack does not include a chest strap by default, but the shoulder straps have attachment points that make it compatible with a standard sternum strap (sold separately). For cycling or fast walking with a heavier load, adding one significantly improves stability and keeps the bag close to the body.

How do I clean and maintain it?

The smooth waterproof surface wipes clean easily with a damp cloth after use. For deeper cleaning, hand wash with mild soap and cold water, then air dry completely before storing. Avoid machine washing, tumble drying, ironing and bleach — these degrade the PU waterproof coating and reduce long-term performance.
