A pair of stretch pants from Wrangler with the color of your choice : $27
If you prefer a hunting brand the UA Ridge reaper pants have zippers on the legs : $100-$160
UA Iso-Chill Brush Line hoodie. They protect you from the sun, they dry really fast. $55.
$80 pants and top combo for hot weather is all you need. Or you can spend $400 and look cool.
I don't like Merino wool for really hot weather. Merino is delicate, is expensive and it doesn't dry fast enough. They are great for first layer on cold/cool days but IMO not for hot days.
Synthetic fabric dries a lot faster and it is surprisingly durable.
The Merino wool scent managing properties are legit, but to me, not worth the trade-off on hot days.
I prefer to spend the money on packs, boots, sleeping gear, glass and such.
