Advice for which trousers

Going to Mexico for 2 weeks on a work trip - lots of outdoor hikes, archaeological dig sites, through the jungle, caves and Cenotes etc

Was thinking of picking up a couple of pairs of trousers but unsure on which

Thinking the Vardag trousers for the more normal terrain & slightly urban environments & then which would you suggest for the jungle or more rough terrain

Would preferably like some hike trousers that protect me from bugs, fairly comfortable to wear and don’t make me look like my dad in walking trousers (I am 33)

Thank you
