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.

Great look and very powerful - consider what your wanting to froth/mix - may be too powerful
Color: Lux White, Size: Rechargeable Z1 Motor Max
It's a great frother - but more for large drinks. Very powerful, even on the low speed. I returned it because I want something to mix my collagen and creamer in my coffee. The first time I turned it on it shot half the coffee out of the cup - very powerful. It has a great look, sleek and fits easy in the hand - but for what I needed, two powerful. It would have been nice to have a fully adjustable speed wand like my replaceable battery powered frother.

Powerful, rechargeable battery, easy to use & clean
Color: Lux Absolute Silver, Size: Rechargeable Z1 Motor Max
2 speeds, easy to change back and forth to different speeds with one click , easily blends 1/4 cup protein powder in 12 oz milk on low speed. Easy to clean: Stick blending wand in tall glass with warm water + dish soap, turn on low speed to clean easily (don’t stick the part that holds the battery in glass). Also of note, chosen by Americas Test Kitchen as best milk frother but I use it to make protein shakes.

Works great on bullet coffee!!
Color: Lux Alpha Black, Size: Rechargeable Z1 Motor Max
I am really pleased with this frother! Frothers I have used in the past didn’t mix my decaf coffee, 2% milk, and MCT oil as thoroughly as I like (oil and coffee separated). This frother blends everything AND I get a nice layer of frothy milk on top!!! Charge lasts a long and the froth can be submerged all the way up to the button!!!

Compact, lightweight, and useful milk frother.
I ordered the Electric Handheld Milk Frother in the Starlight Black color. I don’t drink coffee, let alone fancy coffees where I would normally need a milk frother, so I bought this for one reason and one reason only: scrambled eggs. I make a ton of scrambled eggs. Now, I can whisk eggs by hand just as well as the next person, and I’m not entirely convinced a frother whips them better than I can, but regular whisks take up a ton of room in my drawers and this does not. I really just wanted something compact that could whip my eggs into a nice frothy consistency without taking up much space. Even better, this one looks nice enough to just leave sitting on the counter where I can grab it easily. I will note that although I can hand whisk easily enough, there are many people who cannot due to arthritis or other issues, and this whisk is a brilliant tool for them. If you actually want to use a frother for other things, this one does perform very well. It has three speeds and comes with three different attachments: a spring whisk for latte and cappuccino foam, a balloon whisk for eggs and cream, and a hook whisk for blending protein powders or mixes without lumps. I actually ended up using the hook whisk while making pot roast. I mixed the seasoning packet with water using this frother and it blended everything perfectly with no lumps at all. The frother itself is lightweight, pretty quiet, and very easy to clean. The attachments detach easily and just need a quick rinse under soapy water. It also comes with a magnetic wireless charging dock that uses the included USB-C cable. The docking connection is simple and secure, and charging has been completely hassle-free so far. The LED display shows battery levels at 25%, 50%, 75%, and 100%, which is useful for knowing when it needs to be charged. Overall, it’s a simple, convenient kitchen gadget that does exactly what I wanted it to do and I am quite satisfied with it.
