Castelli Premio Black Bib Shorts

£220.00

The Premio Black works impressively well in a wider range of temperatures than most: the thinner material wicks very effectively, but the tight weave means you can also stay comfortable in lower temperatures than you would in most shorts designed for wearing above 25°C.

Despite the leg and seat area being made up of only three panels, each of the same material, within each panel that same material has different qualities and thicknesses...

Down at the bottom of the leg, for example, Castelli has essentially sewn elastication into the material in a lot of little dots that stretch for the first 9cm from the bottom of the leg, in place of traditional silicone gripper. This means they sit close to the leg and keep the shorts in place without any uncomfortable pulling that you would almost certainly get if you had used a similar amount of silicone gripper.

Each leg end is finished with a seamless laser cut which creates a close fit against the leg. This has a number of benefits, including reducing irritation and weight, and improving their aero qualities.

Castelli has used its range-topping Progetto X2 Air Seamless pad, which has variable densities and gel padding throughout, combining to make an undeniably comfortable chamois that’s breathable too.

Overall, these are genuinely innovative bib shorts that feel like a technological leap forward.
