Sizes change, seasons change, skill level changes – for whatever reason, sometimes your old gear doesn’t cut it anymore.

When it comes to selling or trading used skis, boards or paddles, you’ve got a few routes to choose from. If you’re just looking to make a little cash with a few items, selling online might be your best option. If you’ve got more gear to give up, and/or if you’re into the idea of swapping for some new-to-you goods, a gear swap is something to consider.

Sell it online

Craigslist is an option, but not the only one. You’ll probably reach a better audience going with an organization that deals with outdoor gear specifically.

The process is pretty simple with GearTrade; click “Sell,” upload photos, describe your goods, and assign a category and a price. They offer a couple of cool features, like calculators for shipping costs and percentages off the retail price.

Mountain Equipment Co-op offers a similar service, with the added option of opting to trade rather than sell your gear. Ditto BoaterTalk if you’re selling rafting/paddling gear.

And take that last site’s advice regarding scams: “You should actually EXPECT people to try to scam you when you post direct contact information. Direct and anonymous access to you is what they look for.” Middlemen exist to help keep you from getting screwed.

Attend a gear swap

Gear swaps range from neighborhood get-togethers in the church parking lot to massive events held in conjunction with gear conventions. Check your local newspaper or the calendars for your city’s expo centers to find out what swaps are happening near you.

Organize a gear swap

If you know other folks in your area who might have gear they want to get rid of, putting together your own gear swap is doable with a little advance planning.

1. Choose a location – ideally, a pretty big one. Your garage might work, but a big chunk of your grocery store’s parking lot or local community center might work better. Ask about fees/insurance before booking the space.

2. Set a date and recruit volunteers to help you assign values to gear and figure out general bartering rules. Make a list or guide that defines terms like “barely used” or “like new.”

3. Create areas with signs for types of gear – fishing, boating, skiing, surfing, whatever you’ve got coming in.

4. For smaller swaps, going with a general “one for one” rule might work out. But if you’ve got everything from fly hooks to kayaks coming in, set up an exchange system. One way is to buy a large roll of tickets and have your volunteers assign a ticket value to attendees’ gear when they bring it in. Their gear goes into the appropriate section with a clearly labeled ticket “price,” and they spend their tickets on new-to-them stuff.

5. Expect leftovers – best to decide in advance what you want to do with them. One option is to box them up and donate them, another is to let your volunteers divvy the goods up.
