    This review is for Alpinestars Vapor Knee Guards
    Pretty nice - Guso   Antioquia Recommended by Reviewer: Yes
    Pros: Slim enough to be under jeans, and seems safe
    Cons: upper strap doesn't keep in place

    It's just what I was looking for, an affordable and discrete protection to my already broken knee, the straps are somewhat annoying but not that much, the protection seems enough and feels confty

    This review is for Alpinestars Bionic Air Back Protector Inserts
    Big improvement - WaynoJ   WA Recommended by Reviewer: Yes
    Pros: Light weight, excellent protection
    Cons: Won't fit all jackets

    I've been looking to upgrade the back protection on several of my riding jackets, and this looked to be a reasonably-priced insert. Got the medium size about a month ago and have tried it in my Sliders Carmel and Icon Hooligan jersey. The Bionic Air fits the Icon jacket perfectly, but just barely squeezes into the Carmel jacket -- a large size would not fit. Due to the heavier construction compared to the stock foam pads, the Bionic Air doesn't bend much, so it's harder to fit into tight compartments like in the Carmel. Once it's in, this is a fantastic back protector -- much more protection from pointy objects, and a LOT more padding in the case of a down. I highly recommend the Bionic Air back protector.

    This review is for Alpinestars Touring Kidney Belt
    Riding Belt - Tim   TN Recommended by Reviewer: Yes
    Pros: really provides wonderful back support
    Cons: none

    I purchased this in hopes it would provide some back support on longer rides, and it does. This product allows me to ride longer in comfort without the expense of a drivers backrest on my bike.

    This review is for Alpinestars Bionic Freeride Shorts
    Nearly invisible protection - Harry   WA Recommended by Reviewer: Yes
    Pros: Great thigh and coccyx protection. Allows air flow.
    Cons: Mediocre hip protection. Leg band too tight.

    I bought these shorts to wear under my sliders jeans to add impact protection and they served the purpose well. Be careful when putting them on so you don't tear the fabric by pulling too hard. The leg bands are too tight for my legs and it could tear the fabric. I pushed them up by holding onto the bottom of the thigh pads and that helped me to get them up without fear of damaging them.Riding with them was great. They were comfortable and I forgot they were there for most of the ride. The only time I noticed them was when stopped and I felt the slight warmth under the thigh pads.I'm very pleased with them.

    This review is for Alpinestars Compression Pro Shorts
    Compression Pro Shorts - Michael   CA Recommended by Reviewer: Yes
    Pros: Good quality fabric, sewing and fit. Well placed 'armor' padding. Excellent price..
    Cons: 'Armor' or padding is probably not going to absorb a huge amount of impact without some damage to your body. A lack of front 'personal equipment' access means pulling both pants and shorts down to pee - a little awkward in some circumstances.

    Well made and good fit for my 5' 912, 150 lb., slenderwiry frame. Bought size M for my 31 -32 waist and are pretty comfortable. I feel that they would probably mitigate and soften a moderately serious spill, absorbing some, but not a huge amount, of impact and protect to some degree against abrasion. This is basically what I figured I was looking for, and getting.They don't show at all when worn under my Carrhart logger jeans and are definitely not hot and clingy like I imagined they might be riding here in central coastal CA. in both warmer and cooler weather.I think they represent an excellent value for most general, mildly aggressive riding. However, I also think that if you're looking for a lot of protection for really serious sport riding there are many other more expensive, far more effective options available.

    This review is for Alpinestars Mens Tech Chest Guards
    Chest Guard - Ed T   CA Recommended by Reviewer: Yes
    Pros: Simple to use, light and unobtrusive.
    Cons: Size - wish it were a smudge narrower.

    The Alpinestars Tech Chest Guard simply slips into your leathers, simple to use.Once in place, it stays put and almost disappears. IMO, it's much easier to use compared to the ones that require belts, straps, etc.My critisisms are very minor - I'm a 42 chest, it might fit better if this guard were perhaps an inch or so narrower. Maybe.Otherwise, the front coverage is good.If I were to improve this pad, I would consider using more non-slip material on the back side.And lastly, although it does conform to your chest, it wouldn't hurt if it was pre-curved a little bit more. I like it and recommend it.

    This review is for Alpinestars Mens Bionic Chest Pads
    Protect yer man boobs - JC in NC   NC Recommended by Reviewer: Yes
    Pros: Lightweight, breathes well, makes you feel like a gladiator
    Cons: Price, fit isn't perfect

    I went on a little bit of an armor spending-spree on my Alpinestars T-Breeze mesh jacket in XL lately. I replaced the chest foam padding with their upgraded CE-rated chest armor. They look cool and should hopefully keep my chest protected from any unintended collisions with something moving in the opposite direction. They don't seem to want to sit in place very well though and they sag a little low. While that is to be expected with my age, I suspect it is indicative of my jacket being a bit too large. Regardless, the armor is well constructed and a worthwhile upgrade to any Alpinestars jacket with the chest armor pockets.

    This review is for Alpinestars Flare High Visibility Vest
    Just okay - DB   TX Recommended by Reviewer: No
    Pros: Nice styling plenty bright
    Cons: Fabric was a little flimsy too large

    I didn't exchange it for a medium size because the hi vis fabric was too lightweight and somewhat loose. I pictured it getting a little floppy in the wind.

    This review is for Alpinestars Bionic Freeride Shorts
    too tight - JT   CA Recommended by Reviewer: Yes
    Pros: side and tail bone protection, mesh construction to stay cool
    Cons: waistband is much too tight

    I am a lean guy who wears a 33 jeans and the Large size of these shorts is way too tight at the waist and thighs. I didn't have the time to return these but suggest ordering the next size up. Aside from the sizing these are great protectors.

    This review is for Alpinestars Compression Pro Shorts
    Did not live up to my hopes - Bob   WA Recommended by Reviewer: No
    Pros: Wear street jeans with this and knee pads and have the armor you need.
    Cons: Pad placement

    Thought this would be a good idea but the placement of upper rear pad just hit me wrong. I ride 6 to 8 hours many days and I will not be able to were these on those days.
