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.

Arrived whole
Style: Tree Pattern, Style: Tree Pattern
I noticed several posts where the holder was cracked and damaged. mine arrived fine but it came inside a larger box due to other items arriving with it so not sure it that helped, for future buyers. We've been remodeling our kitchen for over 1yr and a half. Most of the items I have were passed down when my mother passed. The silverware I had didn't match and it drove me nuts. I finally was at the point I could afford to replace all of it. So tossed it all out when these arrived. These are nice looking, very strong and feel of good quality. I picked the hammered look and black since the colors in the kitchen are steel, black appliances and the cabinets are a blue with marble counter. We bought marble dishes and wanted something other than steel silverware. Though the black, at a glance looks like plastic silverware due to how shiny they are. But I am happy. #1 thing that sold me were the steak knives. Serrated knives in set like these are usually just four. The teeth on these are sharp and when I used one on a cold cooked chicken breasts it cut through nicely and shredded it fine without issue. Most sets are usually just four of everything. I have family members every who come over every so often and we would like to host friends once in a while as well. So we needed more than four which at times is hard to come by. I also wash my dishes by hand. I haven't used a dishwasher in 22 yrs, so when remodeling I didn't waste money buying one. So far with washing these by hand, I have had no issue. No rust or odd spotting and no coloring chipped. So would likely suggest washing these by hand if others have issues with them in the dishwasher. For the price, the quality and the quantity, that alone is a steal for me. I didn't care if the holder arrived broken or not. Even if it didn't have the holder I would pay the same and buy this set.

Good value
Style: Heavy Duty
Nice set. The storage tray is too small for 18” drawers and too big for 15” drawers. Could be trimmed to fit the 15” drawer without impacting functionality. Has steak knives and butter knives but the butter knives will cut any steak I’ve ever had. Salad forks seem small to me but none of my guests commented on it.

Kitchen finds

I absolutely love the size, finish and sharpness of this set. There’s nothing worse than a knife or fork that can’t cut through a piece of meat and it’s tender: easy fitting grip and use. Dishwasher safe. I’ve already purchased a second set. lol
