Troy Lee Designs Liner Shorts

Fabric Tech and Breathability Explained

The TMF® pad is the core of what makes these liners work. It uses multi-density foam construction, meaning different zones of the chamois offer different levels of support - firmer where you need impact absorption, softer where you need pressure relief. On a long Welsh trail centre day, that translates to noticeably less fatigue in the saddle. It's not a single block of foam doing one job; it's a considered piece of engineering managing several demands at once.

The moisture-wicking mesh surrounding that pad is equally important. Under a pair of baggy shorts, airflow is always going to be restricted - that's just physics. So the fabric itself has to move sweat away from the skin fast. The four-way stretch panels flex with you through every position on the bike, from seated climbing to standing over the bars on a drop, without bunching or pulling. On a muggy August climb through woodland - the kind of sticky, airless ascent that has you soaked before the top - the mesh keeps things manageable rather than clammy. Quick-drying synthetic construction also matters if you're on a multi-day bike park trip and relying on kit being wearable the next morning.

Flatlock stitching throughout means no raised seam edges pressing into skin over the course of a four-hour ride. It's a small detail that makes a significant difference on anything longer than a quick evening blast.

Getting the Fit Right

Liner shorts need to fit snugly. That's not a style preference - it's functional. If the shorts are loose, the chamois pad shifts around under load, and a moving pad is a pad that causes saddle sores rather than preventing them. You want a compression fit: secure, close to the skin, without cutting circulation. If you can feel the waistband digging in when you sit down, go up a size. If the leg hem is loose enough to move freely, go down one.

The wide elastic waistband sits flat and doesn't fold over when you're bent forward in an aggressive position on the bike. That matters more than it sounds - a waistband that rolls is uncomfortable and can expose your lower back on chilly mornings. The silicone leg grippers at the hem are what keep the shorts locked in position during hard pedalling efforts. They grip the thigh without constricting, so the chamois stays exactly where it was when you set off, not bunched up somewhere unhelpful by lap three of the trail. Check the sizing charts carefully before ordering - TLD run true to size across most of their apparel, but liner fit is worth double-checking given how much it affects comfort.

Pairing Your Liners and Keeping Them in Good Shape

Liner shorts work as a foundation layer, so pair them with a dedicated outer layer rather than wearing them solo on the trail. For most UK riding, TLD MTB baggy shorts are the natural match - the waistbands align well and the fit is designed to work together - but these liners sit low-profile enough to go under any brand's baggies without bunching. For colder or wetter days, layering them under TLD riding trousers gives you full protection without sacrificing that base-layer comfort. If you're heading into proper winter riding, TLD bib tights are worth a look for a fully integrated cold-weather setup.

Wash care is straightforward but worth getting right. Turn them inside out, run a cool machine wash, and skip the fabric softener entirely. Softener coats the fibres of the moisture-wicking mesh, blocking the very function it's supposed to perform, and it degrades the foam in the TMF® chamois over time. Air dry rather than tumble dry - heat breaks down the foam density faster than anything else. Treat them well and they'll stay functional for a long season of riding. Also worth pairing with a quality TLD base layer up top to complete a consistent moisture-management system from waist to collar.

One more thing: if you're new to liner shorts, skip the chamois cream on your first few rides and let the pad do its job. Add it in if you're going beyond three or four hours, or if you know your skin reacts to long saddle time. You don't need to go overboard - a thin application before a long ride is plenty.

Completing the protection picture, it's worth taking a look at TLD body armour if you're riding anything with consequences. The liners handle comfort; the armour handles impacts.
