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.

Wonderful
Size: 9 Inch, Color: Red
Just bought my second one for my German shepherd. 1st one I bought a year ago. She managed to pop it within a few days. She still was able to play with it by grabbing ahold of the straps. Takes it everywhere. We call it her tether ball. Should've seen her when we got the new one out of the box. Hasn't left it alone since.

Keeps him busy. Puppy proof
Size: 6 Inch, Color: Independence Day
Thankfully I bought 2. One of the pumps broke as I was trying to blow up. That is the reason i did not give then 5 stats. This is a great toy for my puppy. Keeps him entertained and is pretty sturdy.

Great for dog self play
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
So much fun for my puppy. Easy to grab and throw for him to play alone. Durable for a medium dog. This is his favorite toy. I also bought one for my friends cattle dog puppy who went bonkers with it. Yet her dog liked to chew the tags off. So I wouldn’t recommend for chewers.

Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab. She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball. The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.
