Why We Like The Castelli Fly Vest

On rides when we need a little bit more protection, we throw on the Castelli Fly Vest and then basically forget it's even there. The vest is so light that we can be forgiven for almost forgetting about it, and the only reason we remember it's there is because of all the protection it offers. Light insulation offers a little extra heat retention, but it really shines on windy days as we put our heads down and cut through the wind like an arrow. With three deep back pockets, we can bring plenty of hydration and some snacks to break through the bunk, and the zippered security pocket keeps our phone and keys close while we push ourselves to the finish line.

Well-made, odd no-collar, runs small

I returned this product before using it

Fit is on the small side, even for Castelli: I'm 177 cm (5'10") and 70 kg (155 lb), skinny upper body, and size M wouldn't fit if I had either a couple winter kilos on or had a second light layer on, so I'll return up and try the next size up. Stitching and general quality seems high. The choice of no collar for a gilet is very unusual; not sure how it will work out.
