The new ORTLIEB Single-Bag is a minimalist cycle bag with a waterproof circumferential TIZIP zipper. With its 12 litre volume, it easily takes a 13" laptop, DIN A4 files and all small items required for a day's work such as calendar, smartphone etc. An organizer with two subdivided sleeves helps keep things in place plus a dark grey reflector ensures safety on the roads.

The Single-Bag offers the benefits of a shoulder bag, however, with the bonus of having an innovative rack mounting, Quick-Lock 3.1 (QL 3.1). It allows even more comfortable and quicker mounting of the pannier.

Simply insert into the lower mounting element, move towards the rack and slide into the top hooks by a lateral motion from left or right. The hooks lock automatically and disengage by lifting the bag.

The QL 3.1 mounting set features three attachment points and can be mounted to any standard rack. Height and angle are individually adjustable. The mounting components on the bag's rear side are flat leaving the bag's back uncluttered, ideal for use in daily life.

    IP Ratings Explanation

    IP Ratings or Ingress Protection Ratings is an internationally recognised means of rating products of various types in terms of their capacity to prevent dust or liquids from engrossing into them or through them, pretty much all of ORTLIEB’s products bare an IP rating.

    The tl;dr as possible explanation is as follows;

    The first digit represents the products resistance to dust with ratings ratings above 4 being resistant to anything larger than 1mm and ratings of 5 and 6 being pretty much impenetrable.

    The second digit represents the products resistance to liquids, this rating is slightly more complicated than first as aspects such as the pressure of the water being sprayed onto the product and the angle matter.

    A rating of 3 means the product can handle sprays of water hitting it within 60 degrees from vertical (basically, this isn’t a problem unless you plan on riding through a typhoon or on a normal summers day here in the Lake District), ratings 4 and above can handle water hitting it from any direction.

    Products which bare a rating of 7 (such as some of the BikePacking and Attack products) are the Andy McNab’s of the scale as they’ll handle high pressure water jets from any direction and submersion up to 1 meter in depth.

    It’s worth noting that to achieve these ratings, products must be property closed and in some cases with bags which feature roll closures a number of roles are required - each product such have a PDF data sheet available which may detail ORTLIEB’s requirements to achieve the IP rating they’ve been awarded.
