Arai - VX-PRO4 Scoop Helmet
The latest expression of the ultimate off-road helmet, the brand new VX-Pro4 evolved from the much-loved VX-Pro3 model. So it’s still the perfect choice for MX, enduro, and off-road use. Just as in every Arai helmet, the basic and simple organic shell shape is based on the R75 shape concept. The absence of exaggerated edges or protrusions on the shell should not be mistaken for a lack of imagination. It’s a visual demonstration of our commitment to maintaining the integrity of the shell with real-world impact performance.
Notice: Fluorescent finishes used in certain models of Arai helmets are not covered by warranty and may fade with the passage of time and exposure to the elements.
Specs & Features:
- A SMOOTH INSTEAD OF RIDGED SHELL
- The shell itself is consistently round and smooth, maintaining the R75 Shape concept in areas above the acknowledged test line and influencing those below the test line. Here, the rounded chin bar maintains the same compact shell length as the previous model, the VX-Pro3. The result is less protrusion, which has proven to be less likely to catch and dig in during a spill.
- SHELL MATERIAL
- In order to maximize performance, we precisely assemble the shell from multiple proprietary components. Super Fiber, one of the primary materials, costs up to six times more than standard fiberglass but provides 30% higher tensile strength and increased penetration resistance. The cLc (complex Laminate construction) method demands precise and time-consuming assembly by master craftsmen from many individual pieces.
- CHIN BAR VENT GRILL
- Installed on the uniquely rounded chin bar, the stainless mesh grill is now mounted from the outside on the exterior vent cap and can be easily removed for cleaning or damage replacement. The vent cap is also designed to break away from the chin bar in the event of impact.
- REAR DUCT
- The Air-Through top-rear-duct center brace also functions as a goggle-strap locator. The diffusers can be removed or replaced quickly and easily by removing a single screw on the rear-duct center brace.
- GOGGLE-STRAP LOCATOR
- The Goggle-Strap Locator keeps the goggle strap in position even during aggressive, competitive riding. The new top-rear-duct center brace, together with the side port cowlings, also assist in keeping the strap in position on the side and back areas.
- NEW PEAK
- The new peak is 14mm longer and 5mm wider than the previous model for improved ability to deflect roost and flying debris. To compensate for increased lift, the air outlets on the new peak have been made larger as well.
- EMERGENCY RELEASE SYSTEM
- The revised Emergency Release Cheek Pad system has the release tab repositioned and is easier to access by rescue staff.
- REMOVABLE NECK ROLL
- The all-new removable neck roll allows easy and convenient cleaning of the helmet.

A rushed, poorly written guide of how the "experts" can't really explain what Deep Learning is
Format: Hardcover
This book, in every sense of the word, is rushed. I think the authors wanted to establish themselves as leaders of this young-ish field, but does so by sacrificing quality. It also shows that Deep Learning theory has been there for a long time, known by another name called Neural Networks. The interesting algorithms are of MLP, Back Propagation and the classical neural networks. The optimization methods such as Adam are the ones that are new and interesting, and the only ones worthy of in this book. So, essentially, what you get from this book is use A for X, B for Y and C for Z type of dry, un-intuitive, badly written waste of paper.
As for the structure of the book, it's like an example of how not to structure a book. It has some linear algebra, probability at the start (not good enough, and confuses more people and wastes paper). Goes on to prove other algorithms such as PCA (yeah, ok!). Then, talks about how this architecture works for this and that architecture.
So, yeah, if you really want to try out deep learning, don't buy this book. Set up Tensorflow/pytorch/ other library, run the tutorials, find an architecture for the problem you are interested in and start tweaking that. You will have far more fun and would have saved your money.
The praise that this book gets is beyond me. Did Musk even read this book? I doubt it.

The classic textbook on Deep Learning
Format: Hardcover
Deep Learning is the promising direction towards general purpose effective artificial intelligence.
There is an explosion of fruitful research in recent years and a lot of applications pursued mainly from technology giants as Google, Amazon, etc. and outstanding research institutions.
The book "Deep Learning " by Ian Goodfellow, Yoshua Bengio, Aaron Gourville, is an excellent piece of work.
They manage to present rather difficult things in an understandable manner. The theoretical presentation is outstanding typical of "classic" books. Also, the book stays close to the practical applicability of all the methods and discusses applications extensively.
There are a lot of other useful books on deep learning that follow a more practical approach by focusing on a particular deep learning software package, but this one book is certainly much more essential since it provides the required theoretical background in order to be able to do serious work on deep learning.
I consider the book as "must have" for anyone that works on deep learning either in an academic or in an industrial environment.

100% Recommend
Format: Paperback
Invincible Compendium One completely lived up to the hype. From the very first chapter, I was hooked by the story, the action, and the character development. What starts off feeling like a classic superhero story quickly becomes something much deeper, darker, and way more emotional than expected.
The artwork is incredible and the fight scenes are intense without feeling repetitive. Every character feels important and layered, especially Mark and Omni-Man. The pacing is excellent for such a massive collection, and it’s hard to put down once you start reading.
If you’re a fan of superhero comics but want something with real stakes, shocking twists, and strong storytelling, this is absolutely worth reading. Easily one of the best graphic novels I’ve picked up in a long time.

This is the best purchase I’ve made in 2025!
Format: Paperback, Format: Paperback
I don’t even know where to start ever since I finished (in early August, 2025) the whole series of this comic. I have never been this much speechless in my life. It’s my first comic that I’ve ever read and finished it.
I got into invincible through the TV show and I wanted to give a shot on comics because people said it’s even better than the show, and I was blown away just by the tv show until I started reading this.
It didn’t matter how tired I would be and/or how busy I would be, but I’d still make time to grab and read at least some pages very excited.
There are so many parts in this comics where it reflected on my personal life and somewhat opened my eyes of what I had and need to do in my life. It was really fun, exciting, loving, caring, sad and emotional story. This comic has a definitive beginning and a final, conclusive ending.
I loved it overall despite where there were some boring parts, but it all made sense later in the main story. Very well developed characters, stories and art.
Now whenever I pass by my bookshelf and I see these books puts big fat huge smile on my face. I’m glad I have it in my collection. I got to experience in this comic what I couldn’t in real life.
Every other night in random or toughest moment I would think about what would mark do in this situation.
Thank you for this masterpiece ❤️

Amazing story, just don’t buy from amazon
Format: Paperback
Don’t buy these from Amazon. The book is obviously great, but Amazon likes to just throw these into bubble mailers (or even just brown paper bags) and then send them off. No shrink wrap, no padding. Just a big book rattling around loosely in a bag. It will come dented and dinged 100% of the time. Just buy from a comic book shop or eBay seller who actually cares enough to package properly. The content of the book itself is fantastic though. I love this story so far and can’t believe I took so long to get into it. It has such a classic superhero feel while also subverting the genre in so many cool ways. Robert Kirkman can’t miss!
