The Nano Flex Donna Tight from Castelli is perfect the cyclist who desires a women's specific fit cycling tight for cool, wet weather, yet isn't willing to sacrifice comfort, great anatomic fit, and excellent cycling ergonomics without spending over $100. You get the insulation, wind and water protection you need, with great stretch and movement, actual highly useful features, Castelli's most popular women's chamois pad, and a wide, flat, soft yoga-style waistband. This is a tight you can spend quiet, comfortable hours in the saddle with when others are raking leaves or arguing about football.

The heart of the Donna Tight is the Nano Flex fabric. The soft stretchy fleece base fabric is coated with a treatment of millions of nanofilaments that bond to the material, fill gaps, and cause water to bead up and fall off immediately. This impressive water shedding process doesn't prevent the thermal fleece from breathing away excess perspiration or heat, and while not truly windblocking, it does prevent direct and full infiltration by the cold air. Having some air flow helps keep your body temp balanced, as well as assisting with moisture release. Rated for temperatures from 43-64°F, the Nanoflex Donna Tight is a versatile performer thanks to the nanotechnology protection and the essential properties of the thermal fleece.

With the stretch properties of the base fabric, Castelli's designers have been able to build the Donna Tight in limited panels. The pieces of fabric align along the length of the leg, following anatomic cues and moving the seams off areas where chafing is an issue. Despite the protection treatment, the garment has enough flexibility and compression to make this work well, and deliver efficient pedaling ergonomics. The leg openings deploy Castelli's Giro3 wide flat elastic cuff, augmented by the YKK® Camlock ankle zips to create a nice seal around the ankle, preventing air and water infiltration, as well as making the Donna Tight much easier to take on and off. The zipper flaps are banded with reflective tape for increased visibility and safety.

The Kiss Air Donna seatpad is perfect for this tight. It offers just the right level of padding without feeling too bulky. The dimple-like surface of the seamless cover feels soft and smooth against the skin, and is made from a brushed microfiber that essentially eliminates chafing and abrasion. The anatomic, pre-formed shape fits the body well, and is flexible to move with you, also decreasing the possibility of abrasion. The padding itself is a dual density, infinitely variable thickness matched to zones as necessary where more, medium, or less padding is desirable. Air is allowed to move within the pad structure, and relief zones help to ease out heat and moisture. Finally Castelli finishes the Kiss Air Donna seatpad with a bacteriostatic treatment that keeps your skin healthy and protected at the microbial level. This is a great chamois pad for riders who favor hours and mileage over a pure racing environment.

Finally, the details such as the yoga-style waist band, with it's tall rear height, low front, with a soft, over lapping V-shape below the navel, are just perfect and demonstrate how far women's cycling clothing has progressed. This is a cool, wet weather tight designed for women, with impressive specific knowledge and technical expertise that allow you to perform at the level you desire, without compromising comfort or features, as well as not breaking the bank.
