840D ballistic nylon – external shell
A tightly woven, high‑denier nylon chosen for abrasion resistance, structure and long‑term durability. Finished with a triple‑layer polyurethane and polycarbonate coating to improve water resistance and help protect against daily exposure to rain, splashback and surface moisture.

Polyurethane and polycarbonate coating – protective finish
A layered protective treatment that reinforces the fabric against wear while adding a durable, everyday water‑resistant barrier without compromising flexibility or hand feel.

210D nylon – internal lining
A lightweight, hard‑wearing lining material used throughout the main compartments, offering durability without unnecessary weight.

Nylex soft lining – tech areas
A soft, low‑friction textile used in the laptop and tech compartments to help prevent scratches and scuffs on devices during daily use.

EVA foam – back panel & straps
Energy‑absorbing foam used for structure and comfort, providing cushioning and support against your back and shoulders.

Air mesh – back panel & strap underside
A breathable spacer mesh designed to improve airflow and reduce heat build‑up during extended carry.

YKK coil zips – closures
High‑cycle coil zips selected for smooth operation and long‑term durability under daily use.

What is the Day Zip Backpack designed for?
It’s built as a streamlined everyday backpack for work, commuting and daily carry. By focusing on core essentials rather than specialised systems, we’ve been able to make a backpack at this price point without compromising Mous-grade protection, materials or build quality.

Is the Day Zip Backpack waterproof?
It’s water resistant rather than fully waterproof. The triple-layer polyurethane and polycarbonate coating helps shed rain, splashback and surface moisture during everyday use, but it’s not designed for submersion or prolonged heavy downpours.

How does it protect my laptop?
It features a dedicated rear tech compartment with AiroFoam^® built into the base to absorb impact from drops and knocks. The sleeve is padded and softly lined to reduce pressure and prevent scuffs or scratches during daily carry.

What size laptops does it fit?
It fits laptops up to 16"" in size. The internal sleeve measures 298 × 286 × 245 mm, so we recommend comparing your device dimensions to ensure the best fit.

Is it suitable for commuting and office use?
Absolutely. It’s designed around daily commuting, with structured organisation, quick-access pockets and a clamshell opening that makes packing and unloading straightforward.

Can I use it for travel?
Yes. It fits under most airline seats and includes a luggage pass-through strap for rolling luggage. Always check your airline’s size requirements before travelling.

Is it compatible with Mous packing accessories?
It is. The slip pocket inside the main compartment is designed to fit most Mous packing accessories, including tech, toiletry and document pouches.

Is there space for bottles and accessories?
Sure thing. The external bottle pocket fits reusable bottles up to 1 litre while the 13 internal pockets and compartments keep tech, accessories and essentials organised.

How comfortable is it when fully packed?
The backpack uses EVA foam padding and breathable air mesh on the back panel and shoulder straps to improve comfort and airflow during longer carries.

What is the warranty?
The Day Zip Backpack comes with 25-year coverage under our Limited Lifetime Warranty, covering manufacturing defects in materials and workmanship.
