G-Shield Jersey

Given a choice, we'll forgo taking a rain jacket with us if we can. So if it's just sprinkling out and not a full-on deluge, where we'd probably just stay inside to ride anyways, we'll reach for the G-Shield Jersey from Giordana and enjoy a dry ride free from a flapping jacket. It's designed to fit like a jersey because well, it is, yet provides some serious protection this side of a full-on rain cape.

Made with the Super Roubaix Aqua Zero fabric, the G Shield Jersey has a soft, brushed inner-loft that traps warmth and allows moisture to escape. Super Roubaix AZ features a water-repellent, Acqua Zero treatment that bonds with the fabric on a nano-level to keep you dry. For added resilience, the jersey is constructed from a minimal number of contoured panels. This design reduces the number of panels to minimize the potential amount of seams for water to penetrate. These panels also have an anatomic fit around the torso and arms, and they maintain a high amount of stretch due to the interlocking knit of Super Roubaix.

To keep you warm, and to keep the elements out, G Shield uses a silicone heat application at the seams to fill the needle punctures from the stitching, creating a watertight seal that'll keep cold rain from sneaking in. Rounding out the construction, a reversed, full-length Camlock zipper lets you adjust the opening of your jersey for on-the-fly ventilation. The Camlock allows you to open your jersey with a single-handed operation. When you flip the lock back down, your zipper will stay in place.

The G Shield takes a water-resistant approach, not only on the seams, but on the pockets, too. Three rear, fold-over cargo pockets provide ample storage for your ride nutrition and essentials, while protecting them from the elements. For visibility in low-light conditions, a highly-reflective stripe is sewn laterally across the back of the jersey.

    Shoulder Season to Deep Winter Jersey

    This jersey is legit! I bought this because I needed a piece for 40 to 50 degree days. This jersey is perfect! I use G Shield arm warmers to start my ride and take them off if the sun is out or leave them on if it stays cold. The G shield material blocks the wind and moisture, like snow, sleet and road spray beautifully. Allowing me to enjoy my ride. I use a ceramic base layer and bring a wind jacket along on my rides with the jersey. That easily keeps me feeling comfortable into the low 40s. Buy this jersey and your body will thank you!

    Winter Jersey for the win!

    I've put it through the wringer
    True to size
    Size Bought

    Height: 5’9” Weight: 175 lbs Size: L Fit: True to size Initial impressions: When I first felt this jersey, I was surprised at how durable it felt. You can tell as soon as you pick it up that it will protect you during some nasty weather if needed. It is also lightly fleece lined on the inside, so you can bet that it’ll keep you warm during those chillier rides. The material is high quality as is the DWR (Aqua Vento) treatment that the garment received from Giordana. You will notice when you first put it on that it pulls in the chest around the armpit areas and seems short around the belly button area when you’re standing up. This is normal. The bib is made to be worn and to be as comfortable as possible in the riding position. That being said, it’s not going to be particularly comfortable when you’re standing in your living room wearing it. On the bike though, it’s perfect, so no worries there. The zipper on this one is pretty sturdy and easy to find if you were wearing gloves. It’s not the smoothest zipper ever, so you might have a hard time moving it up and down in the middle of a ride. But it’ll definitely hold together during bad weather. My first ride with this jersey, I completely misjudged how warm it really would be. I was used to wearing a light baselayer and summer kit with maybe a vest to get me down to 45 degree weather, so when I woke up for my morning ride, and it was in the 50s, I thought this jersey would work perfectly. Turns out it is made for colder weather than that. I wore this with the G-shield Bib Tights and quickly found that they add about 15-20 degrees of heat to my riding. I tend to run hot on my rides so I ended up overheating on the climb that I was doing that day as the temperatures got into the mid 60s during the ride. Lesson learned. This is a warm jersey. My second ride on this jersey started at 55 degrees or so and the temperatures went in the opposite direction. I wore just the jersey with no baselayer. I really appreciated on this ride as the temperatures got into the 40s that my core stayed relatively warm the whole time. The jersey’s reflective arm band on the left side was a nice feature as I was riding in the late afternoon and a little into the night. I packed a bunch of extra gear in the back pockets for that ride and was able to take them out as needed. I fit a neck gator, gloves, arm warmers, leg warmers, toe covers, my phone, and keys in there and still didn’t feel like they were too full. When there isn’t anything in the pockets, I don’t feel like they’re baggy or anything either. The jersey covers your rear a little more than a summer jersey would, which is really nice for the wet weather. Overall, I think this is a great winter jersey. If you combined this with the other G-shield items in the Giordana lineup, you’d have an awesome wet/windy weather kit. For colder rides where you don’t want a jacket necessarily, this will do the trick. For how it’s made, it breathes really well, albeit not as well as a summer jersey. It’s very comfortable and will allow your fall and spring riding wardrobes that little bit of versatility they were lacking.

    This jersey is an awesome addition to your bike gear. If you are looking for a great way to keep dry and warm, but not have to put on multiple layers the G-Shield is the way to go. This jersey has kept me dry in some fairly decent storms, but also is great for a brisk fall day. The combination of the race fit, and the waterproofing is something you don't get from hardly any other jerseys. The attention to detail across the jersey is super evident. From the reflective elements, to the fold over pockets, and the brushed internals you will love this thing. Obviously more expensive than other short sleeve options, but you really get what you pay for quality wise. I wear a large in LG, Rapha, Gore, Pearl and the large fit me perfectly. Snug like a normal jersey, but with enough stretch that I didn't feel restricted what so ever.

    Good fit. With arm warmers, this jersey will provide the needed warmth when riding into colder elevations without becoming too uncomfortable during the return.
