1. Some of polyester taffeta, nylon are rip-stopped, you can see the check at this kind of fabric, because there are double or triple yarn at ridge, which make the fabric stronger and prevent for tearing.
2. Fabric normally measured by how many “T” and “D”. “T” means quantity of yarn at one square inch, big number means big density. “D” means diameter of yarn, big number means big diameter.
1. Do you know how many kind of sewing constructions of sleeping bag? What is difference?
What’s the sewing construction of your sleeping bag? Is that fit well for your purpose? Does your supplier told you which construction is used for your sleeping bag and feature of each construction? Normally, there are 2 different constructions on the market, the H chamber and double H chamber.
The H Chamber is simplest and most popular construction, sew the shell, insulation and lining together directly. This construction is usually used for summer-spring models
Double H chamber, which is most popular used for low temperature sleeping bag. There are 2 separate layers, the outer layer sew shell & one layer of insulation together and the inner layer sew lining and another layer of insulation together, then sew 2 layers together. This double H construction could have more insulation and better performance than H chamber to keep sleeping bag warmer. After lots of thermal insulation test with “thermal dummy”, we find there’s still “Cold Points”, so we apply an improved double H construction.
Improved double H chamber, as it’s name shows, it’s improved based on double H chamber. The sewing line on double H for both 2 layers are at same level, thermal will loss through these “cold pints”. In order to solve this problem, we designed this improved double H chamber.
2.Does your sleeping bag waterproof?
If somebody tell you that their sleeping bag is waterproof, you should consider if he/she is in this line. Sleeping bag should NOT waterproof, it need to be water repellent and breathable. If a sleeping bag is waterproof, it will not breathable exclusive some extremely high level fabric. The consumer will sweat and feel very uncomfortable.

It depend on different sleeping bag construction and different material used for. Please feel free let us know if you want a machine washable sleeping bag.
