I bought this t shirt a couple of weeks ago through surfstich. 55% hemp,45% cotton. Feels a lot lighter than linen. I have a 100% hemp button up shirt that feels as light but seems more tightly woven or maybe because there is no cotton in it, it feels thicker. Glad I got it. Was in Brisbane working this morning, 32 deg at 11am. Supposed to be 38 but no worries here, HEMP will make life easier.So looking forward to this week coming, it's going to be big....
