Bought this material with the idea of making an ultralight inner double wall tent.
I was informed this material would allow moisture to drip through.
I formed a bag from this material and filled with water, and yes it does leak when you rub the material with your hand, but with an extra coating of DWR water drops may bead up and run off.
My feeling at this point: (A) This material is certainly significantly more water-resistant than open mesh mosquito netting often used on inner tents; (B) It is very breathable; (C) It is strong for its weight; and (D) It is lighter than most materials used for inner tents.
The main purpose of a double wall tent is to try to maintain a temperature above the dew point inside the inner tent.
We will see if this idea has merit.
