Castelli Cold Days Long Sleeve 2nd Layer in Black

The Castelli Cold Days Long Sleeve 2nd Layer falls somewhere between a base layer and a traditional mid-layer. It's incredibly breathable and good at moisture management, but also offers the insulation you require on a freezing cold day.Designed to be worn between a warm base layer and a jacket, this stretchy, light garment has a high collar for added warmth and an asymmetrical half zip, which won't interfere with the zips of your other layers or create bulk over your lower torso. It is made to fit close to the body, so it can either be tucked into or left out of bib tights, whichever you find most comfortable.Breathable but cosy, this is the light mid-layer you've been needing to crank up the heat on cold gravel rides, while being slim and breathable enough to ensure you'll never feel constricted.Features:An excellent insulating mid-layer for use during sub-zero, multi surface ridesUses Polartec® Alpha® 90 high-loft active insulationHighly breathable, made from recycled PETAsymmetric half zip, high collarWeighs 101g (M)Castelli comfort range of -8-5°C
