Alpinestars - S-M10 Deegan Monster Helmet

Description

The goal of the Alpinestars Supertech family of helmets was to create the most advanced, protective, and performance-enhancing helmets possible for riders worldwide. With the S-M10, Alpinestars’ Helmet Development team engineered the helmet to offer the perfect blend of excellent ventilation, and unsurpassed comfort, to create a helmet with the lightest weight possible, all without compromising on any other front.

The S-M10’s design offers a smooth, attractive, aerodynamic profile which is streamlined and free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet’s construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider’s head from direct force to the skull and referred to the neck and spinal column.

 

Key Features

The S-M10 shell sizing solution ensures each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide, providing 4 different helmet shell sizes S, M, L, and XL and 6 consumer sizes from XS to 2XL to ensure riders have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact.

Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.

Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head.

Ultra-ventilated helmet with 28 individual intake and exhaust ports, not including the eye port, with 18 intakes and 10 exhausts.

New eject technology includes the eject helmet removal system.

Lightweight ECE 1260g and DOT 1360g for a size medium, 1310g with side pads and 1370g with visor extension.

The S-M10 is available in 2 versions ECE R 22.06 and ECE R 22.06/DOT.

Helmet bag included.

 

Protection

And for rotational acceleration and oblique impact performance, where impact energy comes from an angle other than a linear 90-degree, or right-angle straight impact, the S-M10 exceeds the new ECE 22.06 Peak Rotational Acceleration standard by 76%.

Removable side pads made from a semi-soft polymer for added protection provide a larger contact area to help spread impact energy.

MIPS Multi-directional Impact Protection System.

ERS Emergency Visor Release and a new Visor Extension to provide protection from roost and the sun.

 

Construction

The helmet’s shell construction utilizes a highly advanced molding technology with a multi-composite combination: 1) 3K Carbon, high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell, 2) Unidirectional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy, and 3) Aramid fiber layer which provides critical penetration protection. This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the 4 density EPS liner.

The result of the unique shell lay-up process employed in the S-M10 construction results in extremely effective impact protection. The S-M10 returning linear and oblique impact performance which exceeds current helmet regulation standard limits. For direct linear impacts, which is an impact at a 90-degree angle between the helmet and an object, the SM10 surpasses the new ECE 22.06 standard for 2024 by an average magnitude of 46% for regular-speed impacts. New for the ECE 22.06 standard, new requirements now include low-speed and high-speed linear impacts where the SM10 surpasses the new ECE 22.06 Peak Linear Acceleration standards by 23% and 28% respectively.

My Go-to Face Wash Now, Clean Feeling, NO Residue, Very Affordable
Size: 13.5 Fl Oz (Pack of 1)
I've tried many face wash, trust. And this is the best even for dudes with POC oily skin. I use mostly Korean beauty products. And only premium brands. Premium brand costly but much of the other cheaper products is marketing and waste of money and time. Eurecin Hydrating Face Wash is not expensive, commonly found brand name in drug stores and box stores BUT it has the best cleaning feeling you get for washing your face without harsh chemical ingredients. \ No residue feeling. Very light before, during, and after. I say light, even before, because in the bottle it looks and moves like water, not really gel-like. Slides like water on your fingers when applying...then on your face it feels light too with moderate soapiness when rubbed and cleansing face. After washing your face, you feel like nothing is on your face, not residue oils, no weird medicinal smell. Just the cleanest feeling. And I use it everyday yet it last decently long. It's my go-to cleaning face wash now.

gentle and effective cleanser but a bit drying
Size: 6.8 Fl Oz (Pack of 1)
Update: I added another star to the original rating because I am able to fix the problem of dry skin with a light layer of squalane oil right after washing with this cleanser. Since I utilized moisturizing oil in my routine I no longer have dry and tight skin after cleansing. This cleanser is still effective at removing my mineral sunscreen without breaking me out or cause any irritations. I will finish the bottle and then decide if I will repurchase. I only use a (large) pea size at a time so this will go a long way. Original review: I have combo skin. My cheeks are very dry while the T zone is very oily. I used Vanicream facial cleanser for years. They are a bit drying on my cheeks in winter time but otherwise perfectly fine. I do not like the shiny mica in it, and Eucerin's hydrating cleansing gel has hyaluronic acid so it's supposedly more hydrating. The reality is that Eucerin is no more hydrating than Vanicream and even when used in the middle of summer it's slighly drying on my dry cheeks. Aside from that, it's totally fungal acne safe (just like the Vanicream), very gentle, did not break me out, and has a very pleasant consistency. I will not buy it again given the disappointing hydration capability and higher price (than Vanicream). BTW, I do not wear make up so I cannot compare the two for cleansing abilities.
