After reviewing a range of trousers that are out there, it is striking that practically no producer at this point seems to have developed well-designed pants for outdoors in hot climates.
Fjällräven has excellent design and materials for a Scandinavian climate, but not for hot places. One of their few pants for hotter climates is not zip-off. Arcteryx has a great range of mountain pants, but again nothing that is zip-off. Craighoppers, otherwise often a company with sensible design ideas for mosquito areas, has only one thigh pocket, as if they'd never given thought to what you need when it is hot. Mammut, a company that created iconic mountaineering gear, similarly goes for snugness, not sensible design, with a narrow side pocket. Mayer-Sports, a quality firm from Germany made an attempt with its Marinus 3-zip-pants, with excellent textiles, but it still falls short.
Moreover, you need a large pocket, too, to store the trouser legs you take off.
Leg pockets should be on the side of the trousers, not on top/upper side, as in hot climate you want there to be direct evaporation, and this is easier if the pockets hang off your legs while sitting, rather than lying on them. This is where the Marinus Mayer-Sports pants fail, in having a pocket that is half on top of the left leg. The Fjällräven Abisko has the same problem, with large pockets on the top of the leg. That may work when you are next to a fjord, but not in hot climates.
Also, hot climates often are places with not-so-great sanitation. A sensible thing to carry are tissues or sanitizer, for which you need an elongated pocket. A separate small pocket for medicines or other trinkets that are important to you can make sense.
All of these pockets should close easily, and take account of how you often travel in hot climates – you're much more likely to sit on the ground, for one because there often is less infrastructure, and secondly, because the ground itself is warm. You thus don't want pockets that drop their content when you sit, for example, on the flat back of a pickup truck. Conversely, a zip on the immediate trouser side pocket, as in the North Face Explorer is a no-no, and unneeded. These are pockets for immediate access.
(And what is it with these triple zip offs? The only reason I see for them is that in some hot temperature environments, it's culturally appropriate to cover your knees. Otherwise, in my view, this is feature overload.)
You would think that some designer/company had picked up on these issues, but sadly so far you see little difference on whether trousers are designed for Iceland or Jordan. This is a missed opportunity, not least because you could also suggest sensible accessories for the pockets, helping people be organized, and potentially differentiating your product from the pack.
Salewa, had the perfect design with its Yandua 5C Five Continents pants – but they dropped it from production. On the right for the person [1], a double pocket, which was ideal for a light hat. On the other side [2], two small and one longer pocket (flashlight, medicine, sanitizer). All of this long, with velcro at the bottom of the leg against mosquitoes [3] durable, and quick-dry. Around 2010, I managed to buy three pairs of these pants, and I am still using them on most of my outings. I would pay €150 for a used version, but they are hard to find. The good news: if any company wants to develop good trekking pants, there is a model to aspire to.
I'm currently in the process of trying to reach designers at various companies, and will update if I find anyone who got it right.

Different Design Needed for Hot Climate
So what is the problem? Summer/hot climate pants need a different design from temperate climate pants, not just in textiles. Hot climates typically have stronger sun and shorter days; less reliable sanitation; and higher mosquito risks. Most importantly, in hot climates, the pants may well be the major piece of clothing to carry essential things, as people are not wearing jackets. This is a fundamental difference to more temperate or high mountain climates.
Double Pocket for Hat & Pockets on Side
Let's start with a key feature that is needed in any sensible design for hot weather: a large, ideally double leg pocket on the right. In hot climates, you almost always need to wear a hat, and thus need a large side pocket to put it into, as you may move in and out of cars and houses. This is in addition to other things that you may want accessible for your right hand, so ideally you should have a second pocket integrated. In this second pocket, I typically carry a string and some snacks. Other people carry a map in this pocket.Moreover, you need a large pocket, too, to store the trouser legs you take off.

That may work when you are next to a fjord, but not in hot climates.
Flashlight, Tissues, Sanitizer
What else matters in a hot climate? Ideally a pocket for a flashlight, since hot climates typically have shorter days, and unless you just go on day tours and are reliably back indoors by nightfall, you may find yourself sorting something out in the dark, and having a flashlight, reliably, really matters. My own preference is for the Petzl Zipka headlamp, which packs away well, is waterproof, and can easily be attached so that you can open locks, or carry equipment. |

Long Legs, Fairly Bright
One last item, that often matters: hot climates often have mosquitoes that carry disease. Consequently, clothing should be fairly bright (somewhere between gray and olive) which seems less likely to attract mosquitoes, and makes it easier to spot them. Conversely, you don't want it completely white, as this will quickly show stains. (Bizarrely, some zip off pants are dark or even black, specifically unhelpful in a sunny climate.) Moreover, the trouser legs should be long, to cover the ankles, and ideally it should be possible to close the ankles a bit tighter.You would think that some designer/company had picked up on these issues, but sadly so far you see little difference on whether trousers are designed for Iceland or Jordan.

The Sad Demise of Salewa Yandua 5 C
Yet there once was a design that worked.
