We track 10,316 products in Sports & Outdoors. At $19.60, it sits above the middle of that category, which is $6.88 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 47% off. Only 6,593 of the products we track claim a discount that large — 6.1% of the catalogue sits in the 40-49% band, so this one stands out. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 218 orders for it. For comparison, the median listing we track in Sports & Outdoors reports 126 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.

We have recorded this product’s price on 13 separate days since 2026-08-11, and it has not moved once. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.

If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
