The Chpt3 1.84 Short Sleeve Winter Base Layer is astonishing warm, lightweight and long lasting – a technical reimagining of the merino wool base layer perfectly suited to cafés and mountain tops alike.

The NuYarn fabric technology utilised in the Winter Base Layer is comprised of a nylon core wrapped with merino wool. This composition has been explicitly chosen because it not only improves upon the natural properties of woollen garments but eradicates inevitable wear that comes with traditional wool. The Winter Base Layer is demonstrably warmer, comfier, lighter, tougher and longer lasting than traditional woollen base layers. It even dries five times faster than its competitors.

Perfectly suited to cool weather conditions and designed to be worn directly against the skin, the Winter Base Layer is favoured by alpinists as well as enumerable pro-cyclists for its technical benefits.

What makes the Winter Base Layer even more remarkable is that it masquerades as a piece of casual wear – with an understated, classic t-shirt look that fits a little more loosely than skin tight cycling base layers, the Winter Base Layer is perfectly suited to café stops or even paired with jeans. It retains its shape after washing and is constructed to last.

If you’re looking to invest in a top-tier base layer that will keep you warm both on and off the bike for years to come, then look no further.

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
