What 40 denier actually means
Denier is the weight of a yarn: 9,000 metres of 40-denier nylon weighs 40 grams. Here is why that number matters for a jacket.
Denier measures how heavy a yarn is. Nine kilometres of 40-denier nylon weighs 40 grams, about the weight of a golf ball.
Lighter is not always better
Lower denier cloth packs smaller and feels softer. Higher denier survives rock, bike racks and backpack straps. Our shells use 40D on the body and 70D where straps rub.
The ripstop grid, the small squares you see in the weave, stops a tear from running.
Our promise
Everything we make is tested in the rain room, and repaired free for five years.
