Unlike you I spend months every year at the arctic circle, and I've never heard of Sturka, not do I care about youtube, reddit, surplus, tactical or bushcraft, and I've also never been to an REI or similar.

>>2563234>spends any amount of time in the backcountryI doubt you ever spend a week off the trail when you look like darwin on the trail.
> takes their gear and weight seriouslyYou should take your bodyweight and gear very seriously indeed. In my out philosophy gear weight, as long as it is within your fitness levels to carry it for 20 miles a day is secondary to its function to enable you to enjoy going whereever you want to go in all weather conditions, and not being dependant on trails or huts and other tourist stuff.
