420D PA

The 420D polyamide fabric is extremely robust : thanks to the dense and extremely fine structure of the fabric, both of the polyamide fabrics are extremely tear and abrasion resistant. The double PU coating protects from moisture with a water column of 1500 mm.

600D PES

Woven from 600 denier polyester yarn and with a thick PU coating, this tear resistant and light fabric is highly versatile. Whenever it’s about keeping the weight of the backpack as low as possible with moderate stress, then this is the ideal solution. The “deuter Super Polytex BS” version is produced in compliance with the stringent bluesign® standard. Its features and stress factors are identical.

  • * D stands for denier. This describes the yarn weight. 600D corresponds to 600 grams per 9000 meters.
  • * PES stands for polyester. PES fibres are very tear and abrasion resistant and hardly absorb moisture.
  • * PA stands for polyamide. PA fibres are extremely durable and abrasion-resistant. They are also characterized by high elasticity and low weight.
