Leatt riding gear tends to come up slightly slimmer in profile than many in the industry. Because of this, the Leatt 5.0 Mono Suit was the only suit on test where I wore an XL size on their recommendation. This gave ample room in the legs and the shoulders to wear a layer below on the colder days, but with some excess material in the torso due to my relatively short upper body. With the stretch in the Hydradri MAX material, I was left wondering if I could have benefitted from the tighter fit of the large size. Nevertheless, the internal suspender system in the Leatt onesie ensured it stayed in place and was comfortable during riding. This suspender system is particularly helpful when off the bike, whether it be chilling in the suit, walking with the bike or standing on the pedals, but I’m not convinced it does much when seated. If you’re lucky and find that the Leatt suit is a perfect fit for your body, it’s possible to remove the suspenders and shed a bit of weight and heat if you’d prefer.
There are two real standouts of the Leatt suit: the soft inner lining of the material which makes it exceptionally comfortable when worn, even without anything underneath; and the internal suspender system that gives a very different, more “snowsports” feel. This material is excellent and feels very premium, in fact the entire suit feels like the most premium offering all round. That said, the textured matt finish of the material proved to hold onto dirt the most of the onesies on test, and the seat panel showed signs of wear before the others that leaves me mildly concerned for its durability over numerous winters. Leatt tends to be very good at customer service from my experience though, so I’m sure if any issues were to crop up then your investment would be safe with a replacement provided.
The Hydradri MAX material performs very well, resisting the buildup of moisture inside until you push it hard, though it does run a little hotter overall than the Endura offerings. How much of that is down to the suspender system I’m not sure, but when temperatures climbed it was quite obvious. That said, I didn’t tend to run any of these suits without any clothing underneath, yet the Leatt suit is the only one that would remain comfortable when doing so, potentially beating the lot when it comes to warm weather performance. The DWR coating did a great job at beading water, and lasted a reasonable amount of time. The ventilation is ample, if not quite so effective at dumping the heat, unless you make use of their Climbvent feature by unzipping the front and using the little popper to keep it together in the center of the chest. This does leave the suit wide open and prone to flapping on the descents though, which I suppose is why they call it climbvent.
Storage in the Leatt 5.0 Mono Suit is the best on test, with lots of storage space on the legs and in the long dual-purpose chest pockets / vents. The RaHD hood is pretty neat too, giving lots of option to tailor the level of protection to the conditions at hand; offering great coverage; and staying in put well without having to rely on tension around the chin thanks to the magnet system. I found that the magnet used to fix the hood in place when not in use was hard to find at times, but it didn’t cause too much stress.
In terms of durability, I’d suggest the Leatt material to be slightly more susceptible to damage than the MT500 or Dirtlej suits, but that’s only based on the seat panel wear. It certainly doesn’t feel like a fragile suit and the overall construction is of a high quality, but the material just doesn’t feel to be quite so resistant. That said, the brush guard patches in the most likely wear areas should keep the Leatt suit looking fresh for a long while. Overall the Leatt 5.0 Mono Suit is certainly a premium offering, and will suit riders who value the comfortable feel of the suit when worn and its unique features as an all-rounder.
