Some shitty hack wrote:On their trek, Paul and his three companions wore new stillsuits covered by mottled cloaks to camouflage them in the desert. Though the garments looked well worn, they were actually finer than any Paul had used when he'd lived as a fugitive among the Fremen. Their makers claimed that these durable offworld imports were superior to the simpler versions that had traditionally been made in hidden sietches.
The manufacturers mean well, he thought. They do it to show their support for me, without realizing the implied criticism in their "improvements."
1° Stillsuit is adapted to the desert, there is no need for a camouflage device (I guess)... and Fremen industry which developped it for centuries has a unique know-how. It's impossible that off-world manufactry improve it in any way...
2° Paul is a fremen and would never wear an off-worlder stillsuit : it'd the best way to upset its fellows (and create a politic mistake).
3° It is not relevant regarding the security. Danger come from off-world (BG, SG, BT, Corrino, Harko). Regarding security matters, only the fremen have the trust of Paul for its safety (especially on Dune).
