I used to ride street, and a tiny bit of MX. Just bought a Honda CRF300L, with a number of key Rally mods on the way. Plan is for both literal and figurative light dirt touring (2-5 days).
As basic as this sounds, I am struggling with pants and jacket. it seems either MX-style (add your own potection) or high-alpine thick warm kevlar gear. Could anyone recommend a good pant and jacket that has some level of protection but would not cause a person heat stroke in the deserts?
Your struggle is real. Fit and function is key and hard to figure out without being able to try stuff on. I've had a lot of different gear over the years and it's been a journey of trial and error.
For the higher temps I can recommend the KLIM Dakar pants. I've been using mine for several years, and they make a pretty good compromise for street/dirty traveling. They have cargo pockets and big vent zippers on both legs with hip and knee padding. My current road tripping setup though are my KLIM Switchback
because they vent really well and have usable pockets. Both are on the lower priced tier of KLIM products.
For the jacket you want a lot of vents, and the ability to un-zip from top or bottom. On hot days the ability to unzip both top and bottom has been real nice. My current jacket doesn't have the bottom zip, but I still like it. (Revitt Sand 3)
If budget wasn't an issue I would have a KLIM Baja S4 set for warm climates.
My preference on jackets is to have room to layer up with my own layers so I can wear them around camp or town. Either my KLIM mid layer jacket or my puff jacket. Turns out when you aren't wearing layers the jacket is more roomy and makes air flow even better.
I like to carry a rain jacket that goes over my gear so I can also wear it around camp or around town if needed. Currently I carry a FrogTogg cheap jacket and even though it's bulky it's very light weight. Their ultra-light jacket/pants combo
have held up great for several years, and the pants will fit over my gear. It's also a real cheap option. I carry a set in my Rig and have a dedicated set for the bike.
Personally I have gear sets for multiple types of riding. I used to wear my ADV gear for everything except single track trail riding, but for long dual sport rides that are over-night or multi-day if it's going to be hot and I want protection I use my dirt gear and take the FrogToggs for wind/cold protection and also carry the puff jacket.
ADV Rider flea market is a great place to buy and sell gear from other riders especially if you're budget minded.

Light weight TUSK rain jacket over my gear. This worked for cutting the wind but didn't do well in the rain. I used it twice and have gone back to carrying the bulky FrogToggs.
