This is the first suit I've used on track so I do not have much basis for comparison other than an AlpineStars Hv2 I purchased second-hand (without trying on). Both suits are sz 64 and the OMP has the additional torso length and midsection width to accommodate my 6'5" "tall in the torso" 250ish body.
I live in the southeast so fabric weight was a huge factor and this OMP suit is VERY light! The exterior pocket is plenty large enough to carry a phone and other items around the paddock.
I've only done one event in this suit this past February 2025 weekend @ CMP and used thick underwear to keep myself warm and a hoodie over the top when not in the car. The fabric is wind-resistant enough to tell me all I need now is a balaclava to keep the chills out. I anticipate little concern compared to heavier suits in the coming summer months but will nonetheless consider a cooling shirt as I progress out of DE and into W2W.

The craftsmanship and performance are top-notch, but the cost is steep. Best suited for serious racers.

Love the sleek fit and ventilation, but the collar feels slightly restrictive after long wear. Overall, a solid suit.

The suit feels strong and well-made, but the price tag might be too high for weekend warriors.

The suit fits snugly, especially around the arms. Consider going up a size if you prefer a bit more room.
