Outer and inner fabric material
For our sleeping bag covers and jackets, we exclusively use ultralight yet robust materials. This reduces unnecessary weight while ensuring long durability.
tissue
We don't use ripstop fabric, but rather a solid-weave fabric. Ripstop is a specially woven fabric that interweaves thicker threads within thinner threads at specific intervals. This saves some weight, but the fabric is delicate: as soon as the thicker thread is damaged or worn, the thinner threads are left unprotected and exposed to wear and tear. Our solid-weave fabric is similarly durable to Pertex.
The "Lightful DownWool" jackets and vests also feature shoulder panels and forearms made of extra robust fabric to withstand greater stress.
If required, priming or impregnation.
Our outer material is windproof and highly water-repellent. Depending on the product, we use silicone-free and PFC/PFAS-free impregnations for the water-repellent finish. The specific finish used is indicated in the product description. We place particular emphasis on ensuring that the impregnation leaves the pores of our fabrics open to guarantee breathability.
We use the following for optimal weather protection:
- CHT's fluorine-free ECOPERL technology for optimal weather protection and maximum environmental compatibility
- the PFC/PFAS-free German impregnation BIONIC-FINISH®
- Water- and dirt-repellent impregnation based on renewable raw materials (Zelan™ R3)
Colors
For selected fabrics, we use BEMACID dyes from CHT. Certain dyes used have documented certifications or conformities, such as bluesign® APPROVED or Cradle to Cradle® Material Health.
Material nylon
The outer and inner fabric is made of ultra-lightweight, durable, and recycled nylon (100% polyamide), which feels incredibly soft, supple, and silky against the skin. To ensure the fabric is downproof, mothproof, and naturally breathable without the usual plastic coating, it is stretched over hot rollers to close the pores. This also eliminates the annoying rustling sound, making it more pleasant for the ears.
Material cotton
Skin-friendly cotton fabrics are primarily used in the glamping sector, where we prefer robust and highly breathable inner and outer materials. The long-staple cotton weave results in a stronger, lustrous, and finer yarn, and feels soft and silky.
For sleeping bags that need to be lightweight and offer highly functional temperature and moisture regulation, we use recycled nylon or microfiber. A sleeping bag made of cotton would be about 300g heavier, the packed size would roughly double, and turning over inside would be noticeably more difficult.
We also advise against using a cotton inner lining:
While a microfiber lining may initially feel slightly cooler, it warms up very quickly. Cotton, on the other hand, often stays cooler for longer in damp or humid environments, which actually worsens the sleeping climate. And if cotton were used between the body and our wool insulation, precisely these positive properties of wool – such as temperature and moisture regulation – would be significantly reduced.
Our duvets also contain cotton with 20% SMARTCEL™ fibers, a very soft and gentle blend. SMARTCEL™ is a high-tech wood fiber naturally infused with zinc oxide. SMARTCEL™ provides lasting odor control, inhibits dust mites, and thus contributes to the protection and recovery of healthy, stressed, irritated, or diseased skin.
