Very comfy fit

I got this after trying on my buddies and couldn't be happier! It's a little smaller than other brands and the sizing is M/L, XL/XXL so i ordered the xl after trying the tiny M/L. Im 6'3 and thought it was still a little small but after riding with it found it to be perfect. It has a little more protection around the waist and i had to get used to the feel. Overall great product.

Very Satisfied

Light and well ventilated. Fits well under the jersey and accommodates Atlas neck brace. I was a bit reluctant to go to under jersey protector because of concerns related to neck brace not being secure. This is not a problem and tabs are supplied that connect to the Atlas neck brace should this be an issue - I did not use them and it was not a problem. Roost protection works well. Fortunately, I have not tested impact. Looks to be similar to an external and should disappate the energy well in front and back.

Super lightweight

I’ve worn this twice and it works really great. It’s very light and doesn’t get in the way

Size coverage is good

I'm 6'3", 220 and this A1 (X-Large/XX-Large) has better coverage than the Atlas Defender. I have noticed a lot of the Pro's have this under their jersey. So it should be good. I have not used it for racing yet, but I'm expecting the same durability and quality as the Tech 10's.

Good product, breaths well

Works as advertised and I'm happy with it. It's not a big over the jersey unit but it provides great roost protection while being a minimal unit that you don't feel on. It vents very well which is important for us with the Texas heat.

Compact lightweight. Great for summer

Everything I expected EXCEPT the shoulder protection. Basically there is none.Thus the 4 star rating. However if you are looking for a simple, well vented. good fitting summer roost guard this fits the bill.

Miimalist protection

I wanted something cool and lightweight for the summer. This fits the bill perfectly. Comfy also. You dont even know your wearing it. However, the shoulder pads are basically useless. I feel vulnerable in the shoulder area in a crash. Although twice the price, I will upgrade to the A10. I expected more from Astars

Comfort5/5Sizing - true to size?5/5Style5/5

I wore this under a mesh jacket and still could feel air moving through, so it was comfortable in weather approaching 90 degrees, as long as I was moving. And it was light and unrestrictive, to the point that I forgot that it was there while I was riding.

One warning: The "posts" on the sides of the lower front, to which the buckles attach, are screwed on. I didn't realize that. So I never checked to be sure they were screwed on tightly, and one of them fell off when I took the roost guard off. Fortunately I noticed it in time to retrieve it from where it had fallen, but it could easily have been overlooked, and consequently lost.

Great Lightweight Underjersey Option

I purchased this to wear under my jersey as I don’t like the bulky over the jersey chest protectors. It fits well and offers great protection considering its size and weight. If you’re looking for a super protective unit that covers a ton of area, this is not for you, but it works great for what it is intended for. I am 6’1” and 210 pounds and I went with the XL/XXL and am very happy with the fit.
