Highly insulating base layer for training and racing in very cold conditions. Features include long-cut sleeves with thumb loops and a close-fitting hood for maximum insulation.


Hooded cycling base layer created for the very coldest days

The Deep Winter Base Layer has been created for training and racing in very cold conditions. It is made from two different weights of merino-rich fabric to provide the optimum balance between insulation and breathability. The leading edges – the hood, chest and arms – are made from a heavier jersey material (340gsm) for maximum protection from the wind, while the lower front body and back panel use a lighter version of the same material (240gsm). Both weights of fabric are high wicking, breathable, and extremely soft against the skin.

The sleeves have a two-piece construction to create a more comfortable shape when riding, and are also cut long and finished with thumb loops so they can be tucked securely into gloves. The hood is designed to fit under a helmet and features a ‘frogman’ face which can be worn over the mouth or under the chin depending on conditions. Flatlock seams throughout ensure the base layer won’t chafe and white reflective tabs on the hood and chest provide visibility in low-light conditions.

Rated 5 out of 5 by from An amazing and essential piece of winter gear This is an amazing garment which has greatly simplified my winter riding wardrobe. The material is much thicker than most base layers and I use it comfortably with a thick jersey (the brevet jersey) in temperatures down to -5 degrees. With more windproof outer layers, it will do for colder than that. There is no longer a need for a hat, and my head is always very comfortable. The addition of facial protection makes it ideal. Extremely pleased with this fantastic item.

Rated 4 out of 5 by from Love the Built in Hat Gearing up for a cold weather ride was always a chore for me. Remembering all my layers and gear, specifically a hat. Having a hood attached is a god send, not only keeping the heat in but my face as well. Doesn't itch and keeps the core warm without overheating.

Can you pull the hood down if things warm up a bit? Is the material stretchy enough to get your whole head out through the face hole if necessary?

Asked by: OrthoMatt
The 'hood' can be pulled down over the head.
