Quick answer: For most outdoor gear categories, used gear is the better financial decision at 40–60% below new prices. The exceptions are safety-critical items (helmets, harnesses, ice axes with unknown history), footwear (hygiene and wear patterns), and sleeping bags (compressed loft is invisible on inspection).

| Platform | Best For | Typical Discount vs. New | Notes |
|---|---|---|---|
| Gear Trade (geartrade.com) | All categories | 40–60% | Outdoor-specific, seller ratings |
| Sideline Swap (sideline swap) | Snow sports gear | 35–55% | Large ski/snowboard inventory |
| REI Used Gear | REI-brand items | 30–50% | Inspected and cleaned |
| eBay | Hard-to-find specialty items | Varies widely | Buyer beware; check seller reviews |
| Facebook Marketplace | Local pickup, ski gear | 40–70% | No buyer protection; inspect in person |
| Ski Swaps (local events) | Ski equipment, October–November | 50–75% | Best prices; gear condition varies |
| Poshmark (outdoor section) | Clothing, soft goods | 40–60% | Good for jackets, base layers |
Never Buy Used: Safety-Critical List
Helmets are the clearest case: a helmet that has taken an impact looks identical to an undamaged one externally but may have compromised EPS foam. Always buy a new helmet. Climbing harnesses over 10 years old should be retired; harnesses with unknown history (garage sales, unknown previous use) should never be used for climbing. Carabiners with gate play, corrosion, or unknown drops should not be trusted. Ice axes with cracked or loose head-to-shaft connections are not inspectable without disassembly.
Good Used Buys: What Holds Value and What Doesn’t
Skis and snowboards depreciate significantly after one season — expect to pay 40–60% of new price for 1-year-old gear, and 20–35% for 3–5-year-old gear. Climbing cams (spring-loaded camming devices) hold value well because their mechanical function is inspectable: springs should compress fully, stems should be intact, and axles should be clean. A $80 cam bought new resells for $50–$60 after 2–3 seasons of careful use.
Tents are risky used buys unless you can inspect seam tape and pole condition — water-damaged seam tape and stressed poles are invisible until you are wet in the rain. Test any used tent at home with a hose before field use.
Methodology and Sources
Resale pricing from Gear Trade and Sideline Swap completed listings (2023–2024). Safety guidance from UIAA helmet certification standards and Black Diamond equipment care documentation. Helmet retirement recommendations from Petzl and Black Diamond manufacturer guidelines (5-year retirement regardless of impact history).
How to Inspect Used Gear Before Buying
The financial advantage of used gear depends on actually getting gear that works. For soft goods (jackets, sleeping bags, packs), look for: intact seam tape on waterproof garments — press along seams and feel for delaminated tape showing as bubbling or peeling — functional zippers with no missing teeth or broken pulls, and fill loft on down insulation that compresses and fully returns. For sleeping bags, compressed loft that does not recover indicates old or water-damaged down, a problem invisible in product photos. For packs, check hip belt and shoulder strap foam for permanent compression, and confirm all buckles and load lifters work. For sleeping pads, inflate fully and submerge in a bathtub to locate leaks before purchase.
How Used Gear Depreciates: Price by Year
| Item | New Price | 1-Year Used | 3-Year Used | 5-Year Used |
|---|---|---|---|---|
| GORE-TEX rain jacket (premium) | $500 | $250–$320 | $150–$220 | $80–$150 |
| Ski setup (skis + bindings) | $800 | $350–$500 | $200–$350 | $100–$200 |
| 60L backpacking pack | $280 | $100–$160 | $60–$100 | $30–$70 |
| 3-season tent (2-person) | $400 | $150–$220 | $80–$150 | $40–$100 |
| Climbing rope (dry, 60m) | $280 | $80–$140 | Not recommended | Not recommended |
| Trekking poles (carbon) | $180 | $70–$110 | $40–$80 | $20–$50 |

When Buying New Is the Smarter Financial Move
Used gear is not always the right financial choice. New gear bought during REI Anniversary Sale (May), Labor Day, or Black Friday sales frequently achieves 20–35% discounts — bringing premium new gear to near used-market prices for the previous season’s model. For items with strong manufacturer warranties — Arc’teryx lifetime warranty for manufacturing defects, Patagonia Ironclad Guarantee — buying new preserves warranty rights that do not transfer to second-hand buyers at most brands. New footwear is almost always the better choice: fit, support, and lifespan start from day one, and used footwear conforms to the previous owner’s foot shape and strike pattern in ways that can cause discomfort or injury over long miles.
