Here at ROBO-KIWI we are all about lightweight bike packing solutions. X-Pac is a composite fabric comprised of multiple layers laminated into a single sheet. The layers in the standard pack cloth consist of a nylon face fabric, a polyester “X-Ply” mesh, a waterproof film and light taffeta backing with a water-resistant coating. Developed and distributed by the sailcloth makers Dimension-Polyant, the company discovered that much of the technology they had developed for making specialized racing sails was also capable of producing a unique bag material. A good sail needs to be as light as possible, whilst strong enough to withstand the forces running through it. To retain its intended shape the fabric needs to be stable across all dimensions. It also needs to survive the elements by not absorbing water and being resistant to UV.

The waterproofness and structure of X-Pac make it an ideal lightweight option for our standard model bags. It is used as the main external fabric in the X-Pac Range and comes in a multitude of colours. ROBO-KIWI's X-Pac range uses VX21 Terrain X-Pac fabric, is designed to be very weight efficient and is lighter than many competitors “ultralight” options. However, if you'd like to save more weight, check out the Ultra Light Range.
