components – quality is in the detail

webbing

We use a combination of high density nylon and polyester webbing. All webbing above 30mm width has been tested for tension strength up to 50 kilos.

rubber handle

A rubber handle is both practical and aesthetically pleasing. Our handles provide good grip, comfort and even weight distribution.

buckles and clips

All load bearing buckles clips and d-rings are Duraflex brand, and are of superior quality. They are tested to a tension strength of 35 kilos. These components are selected for their quality and durability, as well as their aesthetic synergy with the style of the bag.

zippers

All zippers on high use sections and pockets are YKK.

All zippers used in STM bags are self-repairing and selected for quality and durability. In the unlikely event that your zipper snags, just run the zip head back over the troubled area and it will correct itself.

adjustable shoulder strap

When carrying the weight of a laptop and other necessities, you need a strong, sturdy shoulder strap. Ours are made from high density nylon webbing and are adjustable and removable. They come with comfortable movable shoulder padding. All fittings on the shoulder strap are Duraflex brand.

mobile phone pouch

How many times have you missed a phone call, rummaging around inside your bag? This pouch is designed to strap to your shoulder strap. If you want to miss your calls, the phone pouch comes off totally and can be stored inside your bag. Pouches fit a wide variety of phones including blackberry, iPhone. They also double as an iPod/ MP3 pocket.

inner sole

A uniquely designed protection system, exclusive to STM backpacks and wheel bags. The inner sole is made from compressed EVA (the same material that your summer flip flops are made from), and provides superior laptop protection in addition to the high density padding already in the bag. It is a canoe shaped lining that sits at the base of the laptop section, stuck in place with velcro. It cocoons the bottom edge of your laptop by physically covering the corners and absorbing shock.

compressed eva

This is a high density compressed padding that is moulded into our design. It provides a semi rigid cocoon that protects whatever is placed inside from bumps, scratches and shock.

stitching

Key load bearing areas, such as those around handles, ends of webbing and shoulder strap attachments are protected by high quality thread and attention to stitch detail. A bartack is a row of stitching that reinforces high stress areas. These areas are internally bar-tacked and then externally cross stitched for further strength.

suspension cell

A protective cell that completely encloses your laptop in high density padding. This cell is suspended off the floor of the bag, creating a gap between the bottom of the cell and the base of the bag further protecting it from.

removable laptop sleeve

All STM bags are multi purpose, but those with a removable sleeve are even more so. The protective laptop cell is completely removable. If you aren’t using your laptop, you have a secure pouch to store it in, and loads of space in the bag for other stuff.

sound port

This port appears on bags that are designed with a portable music pocket. Put your iPod/mini disc/MP3 player in the pocket, thread your headphones through the sound port (plug end threads from outside to inside) and close the pocket completely so your music player stays safe and dry.

back system

There are 2 main elements that make STM backpacks more comfortable to carry that your average bag: - Your back is naturally curved, but a laptop is flat so they don’t fit that well together. We put the laptop section in the centre of the bag, away from your back so that the bag still contours to your shape - We use high density padding and air mesh to construct a shoulder strap and back system designed to carry heavy loads. All backpacks come with either a removable or tuck away waist strap

stabiliser strap

This is the webbing strap that’s attached onto the back of the duplex courier bag. If you wear the bag across your left shoulder, undo the buckle on the right and redo it at the bottom. Vice versa if you wear the bag across your right shoulder. This strap keep the bag flat against your body so it doesn’t thump around when you are running about town.
