GrandTour Sentinel Jersey

(3 customer reviews)


A thermal aero short-sleeve jersey engineered for Spring/Winter training in all weathers.


Our Sentinel GT is the first garment in our GrandTour range to use thinner, high performance fabrics for better weather protection and improved breathability, which makes it perfect for your spring and fall training and racing in cool conditions.

Traditionally, to produce a single layer fabric that is wind resistant, a high density material is produced by stretching the material during the weaving process. Our Fabric partner has created a new material which after weaving, is shrunk with a steam-pressure treatment, before the DWR treatment is applied; The result is a highly malleable and dense fabric that has a fantastic range of movement and fit. And that crucial difference, amazing breathability. The process is called ‘Pressure Weave’, used to produce high performance garments for use in harsh weather.

Wear it with confidence riding under grey skies. With or without armwarmers or as the core of a layering system.


Use with only a base layer from 7 to 16 degreesC.

Sizing guide

The garment is designed to be neat fitting and only requires a thin base layer next to the skin. These are new generation fabrics, so we need to reconsider how we dress for conditions. This requires no extra layering in wind or rain.  If you want a looser fit or plan to wear more garments underneath, please size up.

“Im 34 waist and 42 chest and the XL was a Great fit”–   Mark

If in-between sizes, size up as race fit. Designed for only a light base layer

    First run out in the GT today. 10c but felt like 7 in the strong wind. Didn’t feel it at all on my torso and upper arms, collar sits nice and high so no issue there, in fact I had to unzip on climbs as I was too warm!! Hands were cold as I chose wrong gloves, but the body stayed perfectly warm throughout. Worn with just a thin SS base layer underneath, and teamed up with Galibiers Roubaix bib shorts, this is a fantastic garment.
    I’m a 46” chest, 36” waist and the 3XL is spot on around shoulders and chest, bit flappy around the waist but I can love with that.
    Excellent service as ever, speedy delivery.
    A great addition to my growing Galibier collection!

    This is a lovely piece of kit. Fabrication is high quality, and it feels a bit like a lighter short sleeve version of the Mistral Foul Weather – which from me is outside indeed. I haven’t had a chance to wear it in anger just yet as am recovering from sickness, but I’m pretty confident it’ll perform. It’s a very similar fit to the Mistral (current version – older ones were slightly more relaxed) and similar to previous reviewer, I’m 34/36″ waist and the XL is spot on.
    The 5 stars also go to Galibier’s brilliant customer service. My original order went awry in the post, and they sent a replacement straight away with no quibbles

    Quick delivery. Landed today and wore it tonight for our club ride with the arm warmers. Brilliant bit of kit, windproof and warm. I’m 34/36″ waist depending how much I breath in and 42″ chest XL is perfect. Thanks Galibier
