The surprisingly thin material of the Merino Deep Winter Baselayer belies just how warm it will keep you. Made from an intelligent mix of Merino wool and Polyamide, the Merino Deep Winter Baselayer offers warmth and breathability. The seamless knit has a longer torso to provide as much coverage as possible, while a turtleneck ensures no frigid wind penetrates at your chin. Longer arms with thumbholes make it possible to protect your wrists from persistent wind.

All our baselayers act like a second skin. Extremly slim fit cut with extended back side for lower back protection. Whatever Isadore jersey size you are used to wear, this baselayer will certainly fit you in the same size. However if you prefer more casual fit, we advice you to choose one size bigger than the Isadore jersey you are used to.

    Comfy & practical

    Size is spot on plus extremely comfy base layer, really the most practical addition for winter rides. Only problem is, now i am not using any other base layers!

    Besser geht's nicht

    Fast zu schön, um es "nur" darunter zu tragen. Angenehme Qualität, Membrangewebe auf der Brust, schützt, ist aber nicht unangenehm steif. Trage normalerweise M, hab aber L bestellt und es sitzt angenehm eng. Perfekte Lieferung.Absolute Empfehlung.

    Deep Winter wind cheater

    This is just the best base layer ever… wasn’t keen on the roll neck idea at first but it is perfect soft and comfortable, unnoticeable apart from keeping the draughty condition away from my neck and upper back. The windproof panel on the chest is simply the best thing in my cycle wardrobe.. it works a treat and especially when I have my outer layers open for ventilation this panel keeps chill away from my chest. The material is comfortable against my skin and fits really well, I love the long sleeve length and the thumb holes help when I’m pulling layers on top but I don’t use them afterwards as generally feel them as uncomfortable… however they definitely help make sure the sleeves are not rucked up under my outer layers… so good I bought a second one to keep for fear of Isadore discontinuing this MARVELLOUS piece of cycling MAGIC ????

    Just what I needed

    This base layer is my go-to option for winter morning rides in London. It is light and doesn't save any aromas. Great addition to my wardrobe!
