Alpinestars - S-M3 Solid Helmet

The S-M3 Solid Helmet is built for riders who want a modern off-road helmet with serious protection and a clean, aggressive look.

Key Features

  • Advanced Shell Construction: This helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight. The SM3 medium weighs 1430g (ECE) and 1460g (DOT).
  • Ventilation: Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.
  • Rotational Acceleration Force Protection: Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s own low-friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts.
  • Visor Release: Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider’s neck during an impact.
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
  • 5 EPS inner parts with 4 densities to effectively manage volume and impact perfromance.
  • Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance.
  • Comfort liner is constructed using recycled materials for a lower carbon footprint.
  • The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as genuine spare parts in different thicknesses.
  • Alpinestars has introduced a new in-house standard for the SM3 helmet to test the helmet’s chin to conditions heavier than the homologation standard, and in order to pass the Alpinestars’ new standards, the shell thickness and the structure of the helmet design itself have both been optimized on the chin area for superior impact performance.
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
  • Equipped with an EUPDATEncy Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort.
  • Soft textile chin strap is 25mm for optimal safety and rider comfort.
  • Stainless steel D-rings ensure a tight and secure fit.
  • The SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide.

Amazing read!
Format: Kindle
I loved this book so much! I might be a little biased because I loved the first one so much and I’ve been dying for Ana to get happy ending ever since, but it was definitely a good book all around. Ana and Rachel were absolutely perfect for each other. They have the kind of opposing personalities that fit together like a puzzle. Where Rachel was a little more reserved and polished, Ana was more outgoing and messy. They didn’t clash, they completed each other. I’m not going to lie, love that they’re a doctor and a lawyer because they’re giving sapphic power couple. I also loved all of the supportive family members and best friends in this book. Stella and Charlotte were super cute and I hope we get to see them again in a later book. I thoroughly enjoyed this book and I’d recommend it to anyone looking for an opposites attract, doctor/lawyer romance. This is the second book that I’ve read from Morgan and it seems like she doesn’t miss.

Sapphic Lawyer and Doctor
Format: Paperback
I loved this book… which is why I was very disappointed when the conflict was “solved” so easily and lowkey brushed past. We are waiting for this secret to come out that Rachel has been holding onto. There’s obviously conflict of interest with Ana and Rachel. But the way they solved it? I didn’t feel like it was realistic and it felt like both women were like, “Okay, that’s over, everything is kosher now(pun intended?). It honestly prevented me from giving it 5 stars. The ending seems so rushed. But other than that, I loved both characters! I loved learning about Jewish culture and loved how the author portrayed it. Both MCs are fleshed out, in depth characters. The author had a good balance of humor

Enjoyable Doctor, Lawyer Romance
Format: Paperback
A very enjoyable and engaging story. The medical and legal aspects of this story was very fascinating. I never get tired of reading romances that are about those troupes. The romance between the main characters was very sweet with not A lot of drama or angst. Sometimes I prefer A story with less drama and angst. I like when characters in A story can be reasonable and work out their problems without all the drama. Ana and Rachel are those characters. There's A few witty moments in this book that made me smile and laugh out loud A few times throughout this story. The supporting characters were written well and helped to make this an even better reading experience. I will definitely be on the lookout for more books by this author.

So good
Format: Paperback
When your one-night stand turns out to be the surgeon that you subpoenaed for a malpractice lawsuit. Ana, an unappreciated lawyer, has been passed up for promotion to her male colleagues yet again. A malpractice lawsuit win could be what she needs to finally get the promotion she’s worked so hard for. Rachel, a cardiac surgeon who goes above and beyond for her patients, is subpoenaed to testify in a malpractice lawsuit. Arriving at the law firm for her deposition, Rachel discovers that the lawyer for the family who filed the lawsuit is Ana Mendez. As in Ana, her one-night stand. I was excited to get my hands on this one! I loved that Ana and Rachel were so different from each other in personalities, looks, backgrounds, and religions. The differences made them unique and interesting to me. The banter was well-written, and I loved how feisty they were towards each other in the beginning. Was the dirty talk unexpected? Very much so. I was not prepared for that or for how hot things had gotten. And while I did enjoy the spice, I would’ve liked for there to have been more communication about the conflict too. The references to The Golden Girls and The Sims? Oh, I totally geeked out over that! Overall, it was a good sapphic romance that I’m sure others will enjoy. I’d like to thank NetGalley and Bold Strokes Books for the arc. This is my voluntary review.

A Conflict of Interest Worth Taking
Format: Paperback
This is the second book by Morgan Adams, and I thoroughly enjoyed it! One of the main characters, Ana Mendez, appears in Adams's first book, but that is not a requirement for reading this story about her and Dr. Rachel Cohen. One of the tropes in this book is one night to forever, and I enjoyed the time it took for the two characters to re-meet and figure out their issues. I thought their relationship developed well on the page. It was believable, had some humor, and was QUITE spicy. I liked each character's relationships with friends and family, too; they helped to make Ana and Rachel more than just two women who are well-established in their careers. A Conflict of Interest is a fascinating medical/legal story alongside a romantic one. I would recommend it to readers who want to read about two competent and mature adults who have to navigate their careers as well as a romance. Thank you to the author and the publisher for the opportunity to read and review the arc of this book!
