CHPT3 Monzamilano TT Base Layer 1.81


0 Review

Designed to be worn under the 1.24 Monzamilano jersey the 1.81 Base is also the perfect base for all your riding between April and October.

The 1.81 Base Layer as told by David Millar

This is a microfibre polyester made as light and soft as possible. Its hydrophilic outer layer wicks moisture off the skin to the jersey yet doesn't absorb moisture along the way. We made it a perfect weight so that when paired with the 1.21 jersey you end up with the combined weight of a normal looking jersey only with much better comfort and moisture management.

The neck is a little rounder than normal, more like a vest than a t-shirt. This compensates for the higher necks of the 1.24. I chose a sleeveless cut as this and the 1.24 jersey are designed to be used together. Sleeves on an undershirt can often be more uncomfortable with a short-sleeve jersey.

The design references the final stage of the 2017 Giro d'Italia an individual time trial starting at the iconic Autodromo Nationale Monza, built in 1922 and only the third purpose built racing circuit in the world.

Chpt. /// Care Instructions*

I'm sorry if you have to read this.

These instructions should be totally superfluous.

In a perfect world you are already in the bar having a drink

(or in the bath with a glass of port)

with not a care in the world about locating a washing machine

and barely an idea regarding the existence of care instructions

Life's not perfect though, well, not all the time

So please pay attention and read this carefully,

contrary to my fathers belief system,

this isn't "the manufacturers opinion" these are the facts.


Don't pretend you know how to wash Chpt. /// because you don't and you will ruin it.

1. MACHINE WASH WARM 30C, (use a non bio liquid detergent) or if you have help, handwash

2.LINE DRY (this means hang it up to dry naturally, not tie it to your roof rack).




DO NOT BE LAZY and let it lie around wet and dirty, get it in the wash ASAP,


*if you follow these instructions you Chpt. /// will last much much longer.

For specific care of The Rocka Jersey please follow our Gabba care instructions in our general care Guide Castelli Cafe Garment Care
