Leatt - V25 Enduro 4.0 Mountain Bike Helmet 

Renowned for its ventilation and comfort, this enduro mountain bike helmet has been advanced from the much loved 4.0 full face helmet.

The heart of the the Enduro 4.0 is the structurally sound, and easy to operate, removable chin bar design, but the adaptability goes much deeper. A removable mouthpiece in the chin bar increases ventilation or can be installed to protect you when riding in poor weather conditions. A universal sunglasses dock lets you safely dock your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. And the adjustable visor extends enough to place your goggles underneath, so you don’t have to constantly remove them.

This fully ASTM DH certified helmet is the go-to helmet for enduro riders. Uphill or downhill, E-bike or trail - you name it, the Leatt 4.0 Enduro helmet has you covered. The full-face design with removable chin bar with an incredible strong magnesium lock offers outstanding ventilation and its convenient Fidlock® buckle is easy to operate even when your fingers are cramping with arm pump. 

We all crash. Sometimes hard, and sometimes even harder! All Leatt helmets feature 360 ̊ Turbine Technology. This design utilizes a network of small discs constructed of a non-Newtonian, energy-absorbing material. Because these Turbines can move 360 ̊ (omnidirectional), this technology has two exclusive advantages: namely the reduction of rotational acceleration to the head and brain and the absorption of energy upon impact at concussion level.

I love this watch even though it has some really big flaws.
Color: Tan
I love this watch even though there are some major problems. The quality of the crystal is really clear. I love the way the dial looks. It is very easy to read analog hands. It has a lot of lume on the hands so reading the time at night is not a problem even without the illumination. The indices do not glow as bright but can be easily seen when you hit the light button. I like the colors on the dial as well. I do find the digital dispay to be small and obstructed by the light button. The digital display is also unreadable when you look straight on. It just appears black until you look at it at an angle. The worst part is that the light does not even illuminate the digital display. It is not a deal breaker for me as I don't play on using the digital functions when it is dark. Honestly, I probably am not going to be using the other functions other than time. Setting the analog time is annoying as you have to hold the button and wait until you get to the respective time and it only moves forward. Overall nice looking watch that seems well built. If you use the digital functions a lot this is probably not the watch for you.
