Yes, I can and have repaired my sleeping bags. My pocket rocket stove is very sturdy and has a sturdy plastic case, and we’ve had it for 14+ years. And I think I’d be fine in the forest without a stove, but honestly if I ran out of food I might not last long... I’m not a survivalist.

FWIW, I’d also keep using a pack I liked. But the takeaway shouldn’t be people should buy old fashioned backpacks... they mostly suck compared to modern packs.
