Bushwalking gear is expensive, but it lasts a long time. My Lowe pack was bought in late 1983. My Petzl head torches have lasted about 10 years, and I expect the Black Diamond torch bought a year ago to last a long time too. A while ago I worked out that on weekend bushwalks I have $3-4000 in gear, which is a lot of money. However, if it lasts for 10-40 years then the cost per trip is peanuts, under $5 a day from memory. If you are thinking seriously about taking up bushwalking then buy slowly and wisely. If you are unsure, make do with something else, and avoid places with potentially poor weather. Good gear is sold in the Market square forum on this website.
