Style, elegance, and comfort are the easily identifiable hallmarks of Assos. However, before the advent of 'DB,' the aforementioned was contained to on-the-bike apparel and curios like coffee mugs and throw pillows. But, Dopo Bici has changed all of this, and of course, the DB.55 sportCap isn't exactly your average ball cap. This cap does, however, feature a paneling structure and front brim similar to your favorite team hat, but that's about where the similarities end. After all, Assos doesn't just design products in its casual 'after bike' line to look sharp -- it also makes sure they're as technically sound as the world-class cycling apparel it's been producing for more than 30 years.

Assos made its DB.55 sportCap's front panels and brim with its triple-duty DB.SingSing 205 fabric. This stretchy material forms to your head shape for an individualized fit, is water-repellent, and has a tightly-woven composition that resists abrasion.

For the remaining four rear panels, Assos applied its lightweight DB. Follow 185 fabric. This breathable and wicking bi-elastic material smoothly wraps the back of your head, and it's a touch lighter than the 205. As a system, these fabrics work to both protect you from the elements and ensure that your head remains comfortable and dry.

The Assos DB.55 sportCap is avaialbe in the color Black and features an embroidered graphic on the front panel. It comes in the sizes I (48-53cm), II (53-58cm), and III 59-63cm).

Size I is small. I mean REALLY SMALL

  • Familiarity:I've used it once or twice and have initial impressions

I have a small head. I wear size Small or Medium helmets. So when I saw this cool cap on sale in Size I, I thought, that will be perfect! But Size I in Assos is another world of small. I really wanted this hat to fit because it has such great materials, but it is just too tiny. I would love to get the Size II but they are old sold out. Also I'll mention that the overall appear of the hat is more feminine than shows in the pictures. It is a bit glittery and cursive for a guy to wear. But because of the dragon I'd still wear it if it fit.
