    RST STG EVO 4 One Piece Leather Race Suit

    An outstanding value for a track day suit. Great standard features including a back protector. Very good build quality. Ventilates well and was comfortable on an 80 degree afternoon even though it's black.

    Great track suit

    Posted by Tony on 13th Sep 2025

    This is a great suit for the price! For reference I’m 5’11” 180lbs with a 40in chest and I went with size 42. I’m normally a 40 for a snug fit but I got the tech air plasma as well so I had to size one up to accommodate that and it fits perfect now. I low sided at the track recently and everything did its job really well from the suit to the airbag deployment. Only ended up with a few bruises so it could have been much worse. All I had to do was stitch up a couple places where a thread had burned off but no holes. I was back at the track in a couple weeks.

    I bought this suit based on STGs recommendation, the price point is awesome and the quality is great. Fit is good, no complaints. I tried a few others this one fit the best.

    RST STG EVO 4 ONE PIECE LEATHER RACE SUIT

    Posted by Michael McFadden on 5th Sep 2025

    Great, high quality suit!! I’m replacing a 7 year old RST suit that has held up extremely well doing 10-15 track days a year. This new suit has some nice upgrades, and seems to be at least equal to or better quality as the old suit. For sizing reference I’m 5’10” and a fit 190lbs, and am very happy with the fit of the suit. Highly recommend

    Excellent. This race suit seems more expensive than it actually is. It should be priced at around the $1,000 mark. Recommended.

    First Suit

    Posted by Robert Cadiz on 15th Aug 2025

    This IS my first suit but, I had help from the support staff via back-and-forth emails to ensure I was going in the right direction. I would have been happy if simply the suit fit. Well... it did. Not only that but, this thing is a beast. It appears to be made SO well. I am so happy with it and I'm sure I'll soon fall in love when I take it to the track. I later watched racing on TV / YouTube and what do you know... a good part of the field was wearing RST. VERY HAPPY!

    Amazing Suit

    Posted by lori stone on 11th Jun 2025

    I low-sided a few weeks back on the track and my old well-used suit did its job but wore through the leather. So started the hunt for a new suit. I don’t need to tell anyone reading this how pricey suits can be. My husband recommended I try this brand so I got online and ordered it through these guys, who have been amazing by the way. The first suit I ordered didn’t quite fit so I needed to send back for a bigger size. The whole crew were just really cool about it all. The suit is just great quality for the price. It is really well made. Can’t say enough about it. Hope to get to the track in the next few weeks to try it out. If you’re on the fence just buy it.

    STG RST suit

    Posted by Avi Hadad on 15th May 2025

    Wow! Been riding track only and racing with a Dainese suit. Got to say this suit is WAY higher quality than I expected. Totally worth the money and honestly, kind of more impressed with this one than my Dainese. I’ll need to figure out how to attach elbow sliders to this one. The suit fit really well. Like really well. I’m a 52 Euro and it feels like it’s a perfect fit. 5’ 11” 185lb hope this helps someone
