Rank #8 in Best Slam Ball 2026: 9 Ranked, and the Labels That Don't Add Up
Fashion Thirsty NORTHERN Weight Ball, 3kg–40kg
Price and rating as shown on Amazon when we collected them. Both change.
The Fashion Thirsty NORTHERN Weight Slam Ball sits at number eight in our guide to slam balls. It is listed at £18.99 with a 4.5 out of 5 rating from 137 customer reviews, and the bullet points describe a heavy-duty ball for slams, throws, lunges, squats and presses, aimed at MMA, boxing, cross-fit and rehabilitation work, with a textured non-slip surface.
What the listing never does is settle on a weight. The title advertises a range of 3kg–40kg, but the bullets name only three sizes: 5 kg, 10 kg and 15 kg. The specification table then gives Size as 10kg, Item Weight as 15 kg, and Colour as "BLACK - 10KG" — four different answers to the same question on one page. Everything here is taken from the Amazon listing as it stands, not from any testing we have carried out.
