Water Repellency, Hydrostatic Head, and Breathability — What’s the Difference?
These terms are often confused, but they describe different fabric properties.
Water repellency refers to the fabric surface. A DWR or other repellent finish helps water bead up and roll off, similar to a lotus leaf. Some textiles also combine water, oil, and stain repellency.
Hydrostatic head measures how much water pressure a fabric can resist before leakage occurs. This is usually achieved through a PU coating, TPU membrane, or laminated construction. Outdoor shell fabrics commonly target around 10,000–25,000 mmH₂O, depending on the end use.
Breathability in waterproof fabrics usually means moisture vapor transmission, not simple air permeability. A common MVTR target may be around 10,000–15,000 g/m²/24h, depending on the membrane and test method.
Simply put:
Water repellency = water beads off the surface
Hydrostatic head = resistance to water pressure
MVTR = moisture vapor can escape
A good outdoor fabric needs the right balance of all three.

为什么会有 A、B、C 样颜色呢？
通常我们在收到客人颜色后，会根据客人的要求在实验室里制作颜色样。
一般我们会在一开始根据客供颜色，找到实验室里最相似的颜色。再在这个颜色上做出微调，逐步接近。
当主色在客人颜色范围后，我们再调整色光，也就是我们说的例如海军蓝颜色上稍微偏红一点（看上去颜色会有偏“旧”的有感觉），或者稍微片蓝一点（看上去会偏艳丽一些，颜色更“沉稳”）。
当我们使用 D65（仿北光）来对色（这里不得不提一下，有些客人可能要起 TL84 光源，也有自然光）。我们会找出三个方向最像客人的颜色，制作成 A、B、C 来给客人确认。那么有些客人可能遇到明明不像，为什么供应商会说像呢。这里也就是说大家使用的光源不同，或者角度不同都会带来一些差异。
另外还有一个大货在生产后于颜色 L/D不同，因为有些大货是要求防水，而 A、B、C 颜色样可能没有添加防水。那么大货添加防水后会整体偏红光。
