The SQlab SQ-Short One12 R costs an impressive 270 euros and offers what the ergonomics experts promise: pure minimalism. With an airy material, welded seams and a tight padding that is only four millimetres thick, these shorts are aimed primarily at ambitious competitive cyclists.

The German ergonomics expert SQlab sent by far the most expensive trousers in the test for 270 euros. Our limit was actually 200 euros, which is why the SQ-Short One12 R out of competition here. Bikers who are interested in the special, very thin and extremely firm SQlab pads, but don't want to invest such a fortune, should take a look at the Löffler M Bike Bibshort Concept SQL or the SQlab SQ-Short One12, which we tested in the women's version.

SQlab SQ-Short One12 R - a flyweight

The One12 with the suffix "R" is, as you can easily guess, the lightweight race version of the standard trousers. Almost all seams are taped and ultra-flat. The seamless leg cuffs are perforated with laser cuts, making them pleasantly airy. There are also no seams on the straps. Reduced in this way, the SQlab in size L weighs just 144 grams - and yet the fabric is very durable and robust, as we have already discovered in our long-term test.

The trousers are tight but still comfortable. The sturdy material makes the body feel taut, making you want to sprint straight away. The wide straps keep the trousers perfectly in place without putting too much weight on the shoulders.

There is some criticism for the scratchy seam on the thigh and the slightly scratchy feel of the material. On the other hand, hardly any other trousers are as light and airy as the SQlab, making them an absolute recommendation for hot races and long summer rides.

Special seat cushion

For the seat pad, the ergonomics experts have opted for the thinnest version of their SQ pad. The pad measures just 4 millimetres and is extremely firm. It almost takes you back to the days when leather inserts in trousers provided some comfort. Anyone who is used to sitting in the saddle for long periods in a sporty position will generally have good experiences with this type of padding, as it neither sags nor pushes inwards uncomfortably over time. We do not recommend this type of pad for occasional cyclists and beginners.

Very airy trousers for well-established racers and marathon riders.

Extremely light and airy race bib with taped seams, perforated, seamless leg cuffs and ultra-thin SQlab padding that is barely noticeable. Although the SQlab Bib Short is so light and reduced, the straps and fabric still wrap the body tightly. The material is robust and comfortable, but wrinkles slightly in the hips when pedalling.
