Very good quality helmet for the price.
The quality of this helmet is something you might expect for far more than twice the price. The materials are of good quality, outer shell, padding, straps, face shield, etc. The fit is exactly what I expected for a full face helmet. Just snug enough and comfortable. Also love the flip down sun visor. When it’s up you don’t even know it’s there. But when you need it… BAM!!!! There it is with the flick of a switch.

Best for the Money.
Fits as it should, looks great, and has tinted drop down shield built in. For 1/2 the cost of the Bell helmet I got, this one is definitely better. With the Bell, if I want to use a tinted visor, I need to stop, take it off, and manually change out the visor. With this helmet, I simply flip a switch on the side of the helmet and the tinted visor drops into place. Definitely recommend this one.

Great helmet for sure!!
This helmet does what it should and I would recommend this to anyone. I'm a beginner rider and it serves its purpose. Getting me from point A to point B with a secure and safe feeling. I love the look and I love the comfort of this helmet for sure. The padding inside is perfect. I added a reflective strip to the back just in case. Two very minor negatives about it: 1. The tinted visor kinda blurs sight when combined with the clear visor. I just wear sunglasses underneath, which quite frankly, i prefer anyway. 2. Does not offer enough ventilation. Even while driving the visor fogs up a bit with both vents open. I open up the visor any chance I get. I've now had this helmet for a year and would recommend. I'm sure you'll love what it provides. It's a very sleek and modern look. I hope this review offers some help on your decision making. Happy riding!!

Perfect starter brain bucket
Perfect beginner helmet, no joke. I bought another helmet /cough-scorpionexo-coughcough for twice as much and its absolutely garbage and actually just dangerous the way the wind pulls your head around compared to this waaay cheaper yema. The other helmet sounded like a frieght train from wind noise, this yema is at least 50% if not more quieter. Way more air dynamic also...kinda super impressed with the quality of it especially for the price. Its not your endgame helmet, but a dang nice starter rig for cheap!

Fits good. Comfortable.
My second helmet of this brand. They fit as they should and are comfortable. I like the quick release strap and the built in sun visor. Great helmet.

Quality seems to far exceed the price.
Really great helmet for a fantastic price! Husband loves that it is matte like his motorized bicycle, (thing goes 55 mph so I thought a good helmet was in order.) The drop down sunglasses are an awesome feature. Arrived in a cloth carrying bag which I liked. Looks great, hoping it protects his head as well.

most comfortable full face I've ever owned
My head is in-between sizes... Mediums are almost always too small, and Larges are usually big enough that they catch the wind like a balloon. This large fits very comfortably, and I'm happy. Love the top gun sun visor. Ha.

Wie erwartet
Ich habe mir diesen Helm gekauft um ihn zum Kart fahren zu verwenden. Der Helm ist leicht, die Verarbeitung ist gut und vorallem sitzt er bequem. Für den Preis kann man absolut nicht's sagen. Wie er sich bei höheren Geschwindigkeiten schlägt kann ich allerdings leider nicht beurteilen. Für meine Zwecke ist er jedoch Tip Top.

Für Brillenträger nicht wirklich geeignet ! (Größe L)
Ich habe mir vorausschauende Weise den Helm in Größe L bestellt, obwohl ich laut Maßband und Größentabelle nur Größe M benötigt hätte. Leider sitzt der Helm sehr eng am Kopf, und die Brille musste ich vorher abnehmen. Das anschließende Aufsetzen der Brille war nicht einfach, und die Bügel übten einen ständigen Druck aus. Zum absetzen des Heimes musste zunächst auch wieder die Brille abgenommen werden, da sie sonst möglicherweise Schaden hätte nehmen können. Für Menschen ohne Brille ist der Helm sicher eine preisgünstige Alternative, den anderen kann ich nur empfehlen, den Helm besser gleich zwei Nummern größer zu bestellen.

Buon prodotto, ma difficoltà a trovare visiere sostitutive
Sicuramente il casco ha un bel design, ed è completo disponendo di visiera interna Fumè a scomparsa, oltre che la normale visiera trasparente, due prese d'aria frontali ed altre due dietro, infine il tessuto interno è removibile e può quindi esser ben lavato. Sinceramente l'unica pecca a mio avviso è la non reperibilità di visiere, o almeno io non ne trovo da nessuna parte... Probabilmente il marchio cinese non è così conosciuto da noi

Chulo pero un poco apretado.
Esta muy bien, visualmente muy bonito, pero al menos para mi no es todo lo cómodo que debería, gasto una L y 58cm, cogí la L pese a ser mas grande segun las medidas y aun asi me aprieta bastante la parte de arriba de la cabeza, supongo que con el tiempo dara de si y se ajustara mejor a mi, por lo demás muy bien.

Discreto
Come casco non é male, anche se personalmente mi stringe un po' sulle guance e sull'orecchio sinistro si sente molto rumore esterno proveniente dal meccanismo della visiera scura(può dar fastidio sopratutto per il fatto che il rumore esterno si sente molto solo da un orecchio dando un senso di sfasamento)
