sorry for answering your queries without going through that article. (will read later). I'm answering from my first hand experience.
my hobby is trekking and I've done basic mountaineering course.
on the mountain, I probably won't touch any gear made in India.
we don't have any quality trekking shoe. best (cheapest) option is Quechua and that's a French company.
if we look for quality then Saloman (trekking) or Scrapa, Koflach, La Sportiva (trekking and/or mountaineering).
no local made quality down jacket, sleeping bag, tent, rucksack etc. army supply is somewhat good but bulky. but not at par with imported one.
even we don't have any good local merino wool base layer or quick dry t-shirt, pant.
(not touching technical gears).
Wildcraft is trying a bit but they are far behind foreign companies.
and we go there just for entertainment whereas Army to fight.
point me to any good local made -40 degree gear. a single one.
(from the pictures of ofb tents, I'm little bit impressed on those. it's a good try).
sorry but the situation is very grim. probably no R&D.
P.S. : US seals used Saloman Quest 3d GTX and Saloman is a private entity.
