Excellent Ultralight Cap
Definitely enjoying this cap as a bit of sweat management and sun cover. It is so much lighter than almost any other hat I run with. Janji did take this through all the way through so it means the adjustable sizing is a lightweight tie rather than traditional velcro or cap band. It's great for saving weight but don't know if I like it as much as a standard fastener.
Overall, great hat that I highly recommend.

Best race day cap, lightest!
This cap is super light—just 29 g—and I can’t imagine wearing anything else on goal-race day. I’ll choose either this version or the mesh version, depending on the weather.
I’ve lost count of how many I’ve bought over the years in different colors and patterns. I especially love the white one for sunny or hot weather.

Great Hat
I bought this hat for both style and running in. I haven't done a prolonged run in it yet but it performed well on a short run. The material feels really light and airy.
Its also a great looking hat that allows for that popped-up brim style for wearing around.
