I try to buy things with longevity in mind, and I'll research brands that are known to be "buy it for life" (and I'll see if they're still BIFL or if they've dropped in quality). I usually seek out thrift stores in my area, and if not then I'll see if I can get quality products at discounts.

Here's what I'm into:

- Barbour waxed jacket - Bought for brand new at a significant discount from a retailer in the UK

- Two mechanical keyboards

- Patagonia better sweater fleeces - Although I bought one of my fleeces at full price, the quality, warmth, and fit are second to none and it was 100% worth it.

- Two pairs of goodyear welted boots - Goodyear welting means that the soles can be repaired easily, and I'm aiming to have the boots around for years to come.

- A narrow-width backpack from Timbuk2 - I've heard the brand has dipped in quality, but the model I'd gotten was still classified as BIFL at the time of purchase.

- Zojirushi thermos - It's never leaked on me and years later, it still keeps my water cold for long periods of time.

- Zojirushi rice cooker (a Made in Japan model, versus one made elsewhere) - Bought it used on eBay and it works like a charm.

- Good socks (Darn Tough, Smartwool, etc) - I get mine at TJ Maxx/Marshall's/etc and they're significantly cheaper than getting them online or at a retailer like REI.
