Castelli Pro Seamless 2 Leg Warmers/Knee Warmers

One accessory, two ways to use it

The Castelli Pro Seamless 2 Leg/Knee Warmers are designed to offer maximum versatility, comfort, and thermal protection during bike rides.

The fully seamless construction and highly elastic fabric ensure a comfortable and snug fit, while the wide operating range between 10°C and 20°C allows you to handle various weather conditions without sacrificing comfort.

Their unique structure allows you to use the same product as both a knee warmer and a leg warmer, simply by adjusting its position on your leg.

Knee warmer or leg warmer: choose how to wear them

The distinctive feature of the Castelli Pro Seamless 2 is their great versatility of use.

The length and high elasticity allow you to adjust the position according to your needs:

• As a knee warmer: worn pulled all the way up, they offer greater protection in the knee area.

• As a leg warmer: pulled slightly down, with the top part positioned just above the shorts' gripper, they protect the entire leg.

A particularly practical solution for rides where the temperature can change, allowing you to quickly modify leg coverage without having to carry two different accessories.

Mid-weight seamless fabric

The Castelli Pro Seamless 2 are made with a mid-weight seamless fabric, designed to offer good thermal protection without causing overheating.

The material is surprisingly warm for its weight, yet maintains a comfortable feel even when the temperature rises.

High elasticity also allows the fabric to adapt to the leg, following its movements while pedaling.

Fully seamless construction

The fully seamless construction eliminates traditional seams, helping to improve comfort during prolonged use.

The stretchy fabric wraps around the leg uniformly, allowing for a snug fit without compromising freedom of movement.

This feature makes the Castelli Pro Seamless 2 particularly suitable for both daily rides and longer training sessions.

Exclusive blend of fibers

The fabric uses an exclusive blend consisting of:

• 78% polyester

• 15% nylon

• 7% Lycra®

The combination of fibers offers elasticity, comfort, and the ability to effectively adapt to the shape of the leg.

Ideal between 10°C and 20°C

The Castelli Pro Seamless 2 Leg/Knee Warmers are designed for use in temperatures between:

10°C - 20°C / 50°F - 68°F

This wide operating range makes them particularly suitable for mid-seasons and days when temperatures can vary significantly during the ride.

They are an ideal solution when cycling shorts provide insufficient protection, while full-length pants would be excessive.

Compact and easy to carry

When not needed, the Castelli Pro Seamless 2 can be folded very compactly.

They take up very little space and can be easily carried in jersey pockets, a saddle bag, or a backpack.

This feature makes them particularly practical for rides where you need to be prepared for changing weather conditions.
