For this chalkbag we have combined soft Tyvek® softstructure and the relatively stiff X-Pack® VX21 backpack laminate from Dimension Polyant on the outside. The black X-Pack® gives the chalkbag stability in the lower area and protects it from abrasion. The soft Tyvek® stoftstructure keeps the upper part flexible and light. On the inside, bright red highloft fleece provides a super-comfortable touch and absorbs the chalk. The upper edge is made of an elastic fabric with white Dyneema® fibres. This is actually overkill for the application - but it just looks good and goes great with the other materials. The inner layer of fleece and Dyneema® ripstop can be closed with the cord so that the chalk stays in the bag during transport.
The properties of Tyvek® softstructure are somewhere between soft paper and fabric. It has the texture and feel of paper, but much softer. It can be written on, painted and printed on, but is tear-resistant and can be sewn well. However, it is not quite as abrasion-resistant as a comparable fabric - but the feel and look are unique.
X-Pack® is a backpack laminate that is unmistakable with its diagonally running X-Ply fibres. These strong polyester X-Ply fibres are laminated between the outer fabric and a film or lining on the inside. The result is relatively stiff, waterproof, abrasion resistant and has extremely low stretch. It is usually used for backpacks or bikepacking bags, but also is oerfect for many other applications thanks to its attractive appearance.
