Experience the perfect balance between weather protection and breathability with our Sentinel GT, a pioneering entry in our GrandTour range. Designed specifically for spring and autumn training, this jersey caters to riders determined to conquer any weather.

Rather than resorting to traditional dense fabrics for wind resistance, we collaborated with our fabric partner to innovate. Through the ‘Pressure Weave’ process, the fabric is shrunk post-weaving using steam-pressure. This not only results in a highly adaptable and dense material but also ensures unparalleled breathability. Once the DWR treatment is added, the outcome is a high-performance fabric perfect for challenging weather conditions.

Whether you’re cycling under overcast skies, with arm warmers, or using it as a base layer, the Sentinel GT ensures optimal performance.

Key Features:

  • Windproof SBS anti-stick zip for seamless protection.
  • Over 2 metres of Pressure Weave fabric ensures a smooth finish.
  • Articulated, seam-free collar for a snug fit around the neck in any cycling position.
  • Rear pockets featuring 3M reflective trim for enhanced visibility and mesh drainage.
  • Silicone waistband, uniquely situated at the jacket’s rear, guarantees comfort.
  • Resilient double stitching.

Sizing Guidance: The Sentinel GT is designed for a snug fit, best complemented by a thin base layer. The advanced fabrics usher in a new approach to dressing for varying conditions, eliminating the need for additional layers even in wind or rain. However, for those desiring a looser fit or planning to layer up, sizing up is recommended.

GrandTour Sentinel Cycling Jersey Sizing Chart

Mark’s Experience: “Being a 34 waist and 42 chest, I found the XL size to fit exceptionally well.”

If you’re on the cusp of two sizes, it’s best to opt for the larger one, keeping in mind the race-fit design and intended light base layer.

Care Instructions: To maintain the high performance and longevity of your Galibier gear, follow these care guidelines:

  • Always consult the care label before washing.
  • Ensure all zips and Velcro fasteners are closed and turn the garment inside out.
  • Hand wash or machine wash on a lukewarm permanent press cycle (max 30°C / 86°F).
  • Use only a mild liquid or powder detergent. Avoid products with fabric softeners, conditioners, stain removers, or bleach.
  • Let the garment air dry. Avoid tumble drying.

    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, 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.
    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
