Decathlon’s Kiprun range specialises in offering running gear that punches above its price tag. And while the Kiprun Split isn’t the best 3-inch running short on test, for under £20 it offers no-frills comfort and will do a decent job on race day. 

Looking for gym shorts? These are the best shorts for men

At just 98g, they’re lightweight, roomy, minimal and race-friendly, particularly for shorter distances. A very high-cut side split gives you an excellent range of movement that’s ideal for the faster-paced miles. However, that high-rise cut is a daring look that can raise eyebrows. You’ll have a lot more thigh on show than you’ll find from other, more subtle split short alternatives. If a strong wind blows, there’s a risk of showing off a lot more than your perfect running form. 

Kiprun 3-Inch Split Short features

The sweat-wicking liner briefs aren’t the most comfortable on test. They deliver just enough support and dignity protection but there’s no sign of chafing – at least on shorter runs. We suspect that might not be the case over longer distances, however. There are definitely comfier options we’d choose first for racing half and full marathons.

The Kiprun has some useful storage with a one rear zipped mesh pocket that’ll hold smaller smartphones or a couple of gels plus an internal pocket that’s good for keys, bank cards or other small essentials.

There’s a classic drawstring waistband that’s wide and easy to tweak for a good, bounce-free fit. And we had no issue with cutting, rolling or pressure points. 

The Kiprun Split comes in black with sizes from S to XXL – which come up true to size.
