Sell Your Used Wetsuit — 0% Fees

A used wetsuit typically sells for £30 to £150, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Wetsuits sell on thickness and seal condition, and the buyer’s real question is whether the seams and zip still keep water out.

The short version

Typical range: £30 – £150 — see the full wetsuit value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Note the thickness in millimetres and the size, and whether the suit is summer or winter spec.
Check every seam for splitting, the zip for full travel, and the neck, wrist and ankle seals for perishing.
Rinse and dry it thoroughly and check for any lingering smell, which is the standard complaint.

The photographs that sell a wetsuit

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The suit laid flat, front, full length
The zip and its full travel
The seams at knees, shoulders and crotch
The seals at neck, wrists and ankles, plus any tear or perishing

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Thickness, size and type: “O’Neill 4/3mm Wetsuit, Mens Large, Back Zip”. Thickness in millimetres is the primary filter because it decides the season. Say back, chest or zip-free, since surfers have firm preferences.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Thickness in millimetres, stated as body/limb
Size and the maker’s own sizing convention
Zip type and whether it runs fully
Seam and seal condition, and any tear, delamination or perishing

What buyers will actually ask

You will receive the same three messages about a wetsuit. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“Do the seams still hold?”

Stretch each seam and look for splitting or delaminating tape. Leaking seams make the suit cold and the buyer will find out on the first session.

“Does it smell?”

Rinse it, dry it fully and be honest. A wetsuit that was stored damp keeps the smell and it is the standard complaint in this category.

“What thickness is it?”

Read the label. A 3/2 is a summer suit and a 5/4 is winter, and buyers filter on it before anything else.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The wetsuit value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £90 sale — roughly the middle of the range for a wetsuit — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£90
Poshmark	−£18	£72
eBay	−£12	£78
Mercari	−£9	£81
Etsy	−£6	£84

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

April through September for summer suits, with winter suits selling into autumn. Off-season listings sell slowly.

Heavy for its size when folded, so weigh before quoting. Fold rather than roll tightly, and make sure it is bone dry before it goes in a bag.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used wetsuit worth?

Typically £30 to £150 depending on brand, thickness and condition. See the wetsuit value guide.

Do people buy used wetsuits?

Yes, readily, because they are expensive new and often outgrown or replaced. Being explicit about seam condition, seals and smell is what makes buyers comfortable.

How do I get the smell out of a wetsuit?

Rinse in fresh water with a proper wetsuit shampoo, then dry inside out away from direct sun. If the smell persists after that, say so — it will not surprise anyone who has owned one.
