The ThermoAscent Jersey - Burgundy

For those who seek warmth while climbing high through deep winter. The ThermoAscent Jersey. A deep winter super warm long sleeve thermal jersey designed to insulate the body and keep you warm in temperatures down to 2c. (35F) 

Made with a brushed, fleece-lined Italian 'Stelvio' Fabric, the ThermoAscent Jersey offers excellent thermoregulation and moisture management capabilities.

A close-fitting but high stretch jersey, our high collar keeps cold air away from the neck and chest, whilst tight wrist cuffs keep the cold from your arms and wrists.

3 large rear pockets provide ample space for winter essentials, plus a 4th water repellent zipped pocket for valuables keeps things safe and dry. A large deep reflective strip on the rear pocket keeps you seen in the dark or low light, and the black pocket fabric prevents mud or road spray from spoiling the aesthetic of your new jersey.

    Thermoascent Jersey

    I was pleasantly suprised by the jersey. I wore it out on a cold, windy day with just a base layer. It kept me warm enough to not think about the cold (it was about 6degrees out) and the fit is nice and snug to not be a drag in the wind. I like the longer sleeves on this as it gives a nice overlap with gloves to prevent cold wrists. Excellent jersey.

    Great winter clothing

    Brought the jersey and bib tights (thermal) in the hope I would be able to do some winter riding.
    Not disappointed as I’ve been out in temperatures around 1-2 degrees and have remained warm.
    I paired mine with the wind proof gilet to keep the wind off my chest and was really toasty.
    Great fit also
    Great product would recommend!

    Thermo Ascent - a versatile winter jersey

    I am really impressed by my Thermo Ascent jersey. I have already ridden in it, on several occasions, in temperatures ranging from 15 to 3 degrees centigrade. Partnered with a BOC merino base layer, it has coped excellently, keeping me warm, yet not sweaty in all conditions, whether climbing, descending or hammering home on the flat to avoid the rain. Even in the winter drizzle I didn’t get wet and at no point felt the need to reach for my waterproof.

    The jersey has some outstanding features: the long sleeve length and elasticated cuffs means that you can tuck them into gloves to keep the cold out; the body length is good and ensures that the lower back is protected; the high collar keeps your neck warm; the rear zipped pocket easily swallows up an iPhone SE ( the new larger version). So, all-in-all, a great success!
