Clothing Jackets - Mens

The Castelli Alpha Ultimate Insulated cycling jacket is Castelli's ultimate winter jacket. Optimal insulation is combined with full freedom of movement. The outer protective shell is water resistant and at the same time offers good breathability, while the insulating Alpha inner layer keeps you warm. This is a low-bulk, high warmth piece that can be ridden in the coldest weather as a major component of a comprehensive outfit. The outer layer of the Castelli Alpha Ultimate Insulated winter cycling jacket is made of the water-resistant and windproof Polartec NeoShell material. This textile is lightweight and highly effective and it features taped seams on the outer shell, which will ensure you stay dry dry even during longer downpours. The excellent Polartec Alpha insulation has a loft that traps heat and keeps you warm even in freezing temperatures. It is applied in a double configuration. This double Alpha construction gives you a wide temperature range and, combined with the up and down double YKK zipper, allows you to regulate the amount of ventilation you need.

On the details front, the Castelli Alpha Ultimate Insulated is generously equipped with reflective elements for improved visibility in dark conditions. The same goes for the anatomically shaped wrists, which combine very well with gloves. By optimizing this combination, no wind or rain can enter through the wrists. Besides the 3 back pockets, one is equipped with a secure zipper for valuables.
