No such thing. How you balance the trade-offs will depend a lot on your particular climate (especially extremes), riding style, personal preferences, etc. The primary tradeoffs -- nothing I've seen in the market fundamentally changes these core considerations -- really come down to a choice between:
- Built-in waterproofing at the expense of limited ventilation (i.e. Aerostich and similar)
- Superior ventilation with the need for liners or overgear for waterproofing (Motoport and similar)
Various combinations of everything else -- abrasion resistance, armor / impact protection, comfort, quality of materials, budget / value, customer service, etc. -- can be found readily across a variety of manufacturers and gear. But for me, the above two considerations are the real drivers of the decision-making process, followed next by budget. The rest is pretty straightforward to balance against one another.
In hot & humid Chicago summers and damn cold & dry winters, mostly commuting / around-town-ish riding, I use two suits:
- Motoport Air Mesh jacket + Air Mesh front / Stretch back pants, with waterproof liners (mainly for warmth) and waterproof overjacket and overpants for rain. Bought new ~2 years ago, significantly customized, for $$$.
- Aerostich Darien jacket & pants. Bought used and cheap this past winter to retire my pretty damn beat up -- but still plenty functional, aside from some reasonably easily repaired zippers and velcro and ever-leaking crotch -- 20 yo Aerostich RoadCrafter.
The Darien gear is somewhat
superior in winter. Using it avoids the Motoport pants liners for warmth, which I find a PITA (the jacket liner is a non-issue in winter, it's so easy). Though if I didn't have a bit more budget for the used Darien I could get by just fine with the Motoport for Chicago winters. (If anyone gets the Motoport pants liners, have them reverse the hook & loop velcro so the hook is on the pants and the loop on the flap...makes them much less of a PITA.)
The Motoport is vastly
superior in the summer providing incredible ventilation. The mesh isn't as open or free-flowing as less expensive / robust options, but still provides excellent airflow. No vents necessary -- the whole damn suit is one big vent when the liners aren't installed. Total no-brainer for me in Chicago's high heat / high humidity summers.
I guesstimated how many days I ride in the rain vs. how many I ride in heat & humidity. No surprise: I ride a LOT more days in heat & humidity. I decided I would rather be more comfortable on the many, many
hot & humid days and tolerate the minor hassle of adding waterproof gear when it rains vs. enjoying the convenience of built-in waterproofing but being far less comfortable on the many, many
more hot & humid days.
Very high heat (> 85ºF) and humidity is pretty miserable no matter what gear one is wearing. But for me, the Motoport mesh is far less miserable in those conditions, and makes a big
difference in temps and humidity levels between perfectly comfortably and miserable-no-matter-what hot and humid (~70ºF - 85ºF, which accounts for most Chicago summer days).
I've not crashed in the Motoport, but the gear is incredibly well made, with top-notch materials and high quality armor that covers more impact areas than most. My brother's had one for ~10 years and loves it. I wish I'd gotten mine long ago.
Incidentally, I also have the Motoport "Racing" Gloves, which I think are fantastic. Not perfect, but the best combination of options for me. My leather gloves never last more than a year, maybe two. My brother's Motoport racing gloves are also quite old, and still going strong. I expect mine to last many, many years.
None of Motoport's gear is cheap (well, I actually think their gloves are pretty reasonably priced and a fine bargain), but for riding gear my general philosophy is buy once, cry once.
Based on my 2 years experience with the Motoport, my brother's decade-long experience, and loads of other reviews I've seen, I don't expect to buy another riding suit for another 20 years or so.
