Ultralight, durable, and breathable wind cap complete with mesh panels and a cooling sweatband in a crushable design that fits in small pockets.

Outdoor Research says:

Expanding on the best-selling durable lightweight collection, the Helium Wind Cap rounds out its category as minimalist cap reinforced with Diamond Fuse technology. This piece is perfect for the ounce-counting ultra runner who needs a hat that will dry on the move, and stuffs away small. It's even designed to crush down to the size of the pocket in its cousin product - the Helium Wind Hoodie. Two other favorite features include a 360-degree sweatband made with self-cooling ActiveIce™ technology, and a rear shock cord that can be adjusted for size with a single hand on the run.

Outdoor Research's Helium Wind Cap is a lightweight, packable cap that is ideal for fast paced activities where you want some protection fro the sun and wind. This cap uses a combination of fabrics to keep the weight impressively low, allow it to pack down really well and perform well in hot conditions.

The 30D diamond fused Pertex nylon is amazingly durable for such a lightweight feeling material. It has a shiny feel and look which won't be to everyone's taste but it does work well. There are breathable sections along the sides of the cap to help with ventilation and moisture management while the internal headband uses OR's ActiveIce to provide a thin band for further temperature regulation. The highly flexible peak is great for packing it away but isn't going to please every user.
