You’ve seen this Giro Synthe from the outside before.  It’s Giro’s fastest-ever and coolest-ever road helmet, and a design that is changing the game.  The Giro Synthe Mips helmet advances what you find inside the helmet and above the noggin with the Multi-direction Impact Protection System.

Mips is a new technology that is being deployed in more helmets every year.  The basic idea is that the helmet can move around, just a little, when secured to your head, so when your casque-covered noggin collides with some heavy object, like the ground, your head can rotate a little to reduce rotational forces on your head and reduce overall impact.  It achieves this by lining the EPS foam with a “sliding enabler” material and then creating an internal structure called the “Mips Low Friction Liner” which goes around the RocLoc Air and allows the helmet to move while being secured to your head.  The Liner itself is extensively cut out, mimicking the helmet vents to keep cooling and comfort the same.  All this adds only 20 grams to the total helmet weight.
The Giro Synthe helmet design does aero road better. The name comes from synthesis: in this case, synthesizing the aero performance of Giro’s Air Attack and the cooling performance of Giro’s Aeon. Basically, the Synthe does both better.

The aero performance is improved over the Air Attack in the “heads up” position common to riding in a pack. The cooling performance is better than the Aeon. In fact, the Synthe is the coolest helmet Giro has ever tested on their Therminator headform. It’s almost as good as a bare head.
The aero and cooling performance are tied together. The shape is far more compact than the Aeon, with the fewer, larger vents, nineteen in total, leading to larger internal channels. And to help promote airflow, Giro uses their RocLoc Air secondary retention system to actually keep the helmet off the head. By doing this, airflow is improved around the face and through the internal channels to the exhaust vents.
Helping keep the helmet in place is the primary retention system, which utilizes Featherweight webbing for straps, a slimline chin buckle, and lightweight, adjustable camlock buckles under the ears. Where your head contacts the RocLoc, X-Static padding contacts the skin and wicks away the sweat.
Cognizant of cyclists desire to have a home for sunglasses on the helmet, they’ve created dedicated ports for sunglass temples to easily get inserted and removed. No tricks, no wiggling, just off your eyes and into the helmet, and vice versa. They are integrated into mesh panels which themselves are drag-reducing features of the helmet.
There’s another benefit to improved aerodynamics. A quieter ride experience. By reducing the turbulence around your head and helmet, the ride will seem not as noisy. You might even find yourself talking in a lower voice because you don’t have to overcome so much noisy air.
The package put together is sixteen percent faster than the Giro Aeon. It possesses eight grams less drag than the Giro Air Attack in when the head is 30-degrees from vertical. It has two percent greater cooling than the Aeon. It’s thirteen percent lighter than the Air Attack. The official weight is 270g for a Medium, but we’ve seen them come in a good bit less.
The Giro Synthe Mips is not only more aero than aero helmets, cooler than cool, and lighter than light.  It is safer, thanks to an innovative new impact-reducing liner system.

Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older

Another Great Watch From OLEVS
Color: 2942 All Blue
OLEVS makes great and affordable everyday wear watches, and I quite enjoy this large square face watch, with one minor complaint. I opted to try the all blue design, and it looks really sharp. The deep blue causes the smaller accent colors like rose gold, white, and red, to really pop, giving the watch a nice definition and complex look. The size is nice and chunky, and the watch has a good weight, making it feel high quality. The only complaint I have is with the back of the watch face. The four "corners" of this watch on the back aren't smooth, leaving a few rough edges. It doesn't cause any visual changes, but I did have a moment or two where the back of the watch caught a hair on my arm, causing me to feel not so great. This is but a small complaint though. Overall, I'm quite the fan of OLEVS watches for regular and casual wear. They are visually striking, well made, and at a great price point. Highly recommended.

Beautiful OLEVS Luxury Square Chronograph Watch
Color: 2942 All Black
This OLEVS luxury square watch definitely makes a bold first impression. The oversized rectangular face combined with the black stainless steel strap and rose gold accents gives it a modern, high-end look that stands out without trying too hard. It has that “statement piece” vibe perfect if you want your accessories to get noticed. The dial design is where this watch really shines. It features multiple sub-dials, a moon phase display, and luminous hands, all layered into a skeleton-style face that feels detailed and slightly futuristic. While it looks complex, the layout is still readable once you get used to it. The luminous feature is a nice touch for low-light visibility, though it’s not extremely bright. In terms of build, the stainless steel strap feels sturdy and durable, and the watch has a solid weight to it and giving it a premium feel on the wrist. The clasp is secure, though you may need to adjust the links for a perfect fit. The water resistance is suitable for everyday splashes, but it’s not something you’d want to rely on for swimming. The quartz movement will keeps accurate time, and the chronograph functions add a sporty edge, though they’re more of a bonus feature than something most people will use daily. Pros: * Eye-catching, luxury-inspired design * Durable stainless steel build * Multifunction dial with chronograph and moon phase * Comfortable weight with a premium feel Cons: * Dial can feel a bit busy at first * Luminous feature is moderate, not very strong * Not ideal for heavy water exposure This OLEVS watch is a great choice if you’re looking for an affordable timepiece that looks far more expensive than it is. It blends style and functionality well, making it perfect for dressy occasions or elevating everyday outfits.

Amazingly nice watch!
Color: 2942 Silver Black
I'm a big watch guy. I own many watches, of various brands, styles, and colors, along with both an Android and Apple watch. I like being able to pick a watch that goes just right with what I'm wearing. All that being said, this watch is an excellent addition to my collection, and here are my thoughts after having worn it multiple times. This watch looks incredibly nice and is very well made for the price. It's currently around $50, and that's amazingly affordable considering the quality you get. I have the Silver Black version and it's gorgeous. It keeps time without issue and is easy to read, even in the dark thanks to a special coating that absorbs light. There are additional smaller dials inset that are also still easy to read, despite the smaller size. Setting time and date is easy, and I was able to adjust the band easily with the provided adjustment tool. This watch is on the heavier side and I like the feel of it, but I know some people prefer lighter watches, so keep that in mind. Nevertheless, I find it comfortable and classy. Overall, I really like this watch and I highly recommend it. At its current price, it's an instant buy.

Bold and Eye Catching Watch That Adds Style to Any Outfit
Color: 2942 Black Red
I picked up this OLEVS square face watch because I wanted something that stood out more than a basic everyday watch. When it arrived, the first thing I noticed was how bold the design is. The large face and black with red accents really catch your attention, and it gives off a stylish look that works well with both casual and dressier outfits. One thing I really like about this watch is how much detail it has. The multiple dials give it a more high end look, and it feels like more than just a simple timepiece. The weight feels solid on my wrist without being uncomfortable, and the strap fits well once adjusted. I also like that it is easy to read the time, even with all the extra design elements. There are a couple small things I noticed after wearing it. The larger face may feel a bit bulky at first, especially if you are used to smaller watches. The design is also very bold, so it may not match every outfit depending on the look you are going for. Even with those small things, I have really enjoyed wearing it. It is a stylish and eye catching watch that adds personality and works well when you want something a little different.

Love the squarish shape dials are cool and helpful. ❤️‍🔥
Color: 2942 All Blue, Color: 2942 All Blue
There's a lot to love about this watch. The squared profile gives you that big watch look without being gaudy or ridiculous. The blue with gold accents look great with both dress and casual clothes, especially denim. I love this watch's features and I've gotten multiple compliments on it. great value all around. Here's what stands out to me: ✅ The blue with gold accents are really stunning and unique. I've had people start conversations with me over this watch. 👍 ✅ The squarish shape is complimentary for average and smaller wrists (doesn't look too bulky.) ✅ Gold accents look very distinguished, and the blue is great with jeans or a blue suit, very unique. ✅ The sun and moon dial is a beautiful feature that makes me happy. 🤷😅 ✅ The 24hr time dial is extremely helpful. I need to refer to military time so that's nice. 🪖💪 ✅ At a glance, the hands and accents are great for far-sighted folks like me. ✅ It's nice to have a date window at the bottom for quick reference. ✅ The linked watch band is comfortable and has a great symmetrical and slim profile that doesn't add bulk and doesn't pull at arm hair. ✅ The band does not sound hollow or jingle. (why I shake it in the video) ✅ The buttons and time setting are easy to access. I'm really enjoying the quality and look of this watch but if there are any changes in my opinion or its quality, I'll be sure to report back in. 🤞 I hope you found my notes, pictures and video useful. Be well! ❤️‍🔥
