hi please could you advise which products would be best suited to long distance hiking?

my requirements are good support/compression, odour control, padding for the carrying of lightweight (15kg max total with a 7 day resupply).

the hiking underwear looks great but I was considering full compression legging like the running leggings.
We travel long and fast so it is many days between washing the items, so do all items have the nodour fibres?
There will be a fair amount of hiking in desert/hot climates is the fennec items the best to use and how would they cope with backpacking
