Every rider buying their first pair of padded cycling shorts asks the same question, usually while holding a pair in each hand: what am I actually paying for here? One pair is $60. The other is $180. They look almost identical.
The difference is almost entirely in the pad. Understanding what it does, and what separates a good one from a cheap one, is the single most useful thing you can learn before spending money on cycling kit.
What the pad in padded cycling shorts actually is
The pad is called a chamois, pronounced "shammy". The name is a leftover from when it was literally a piece of chamois leather sewn into wool shorts, which riders had to treat with cream after every wash to stop it going hard.
Modern chamois pads are multi-density foam, sometimes with gel inserts, covered in a fabric layer that sits against your skin. They're anatomically shaped rather than flat, and the shaping is doing more work than the thickness.
That's the first thing worth knowing: a thicker pad is not a better pad. Cheap padded cycling shorts often use one slab of uniform foam, and the thickness is there to disguise the fact that it isn't shaped for anything.
What the chamois is actually solving
Most people assume the pad is there for cushioning, like a seat cover. It isn't, or at least that's the smallest part of the job.
Your weight on a bike sits on two bones at the base of your pelvis, the ischial tuberosities, or sit bones. On a properly fitted saddle those bones carry the load, and the soft tissue between them should be carrying very little. A good chamois supports that arrangement, with denser foam under the sit bones and thinner, softer material in between.
The second job is friction. Over three hours you'll turn the pedals somewhere around 15,000 times, and every one of those rotations moves your leg against your body. Bare skin against a seam, or against fabric that's shifting around, will chafe. The chamois moves with you as one piece so nothing rubs.
The third job is moisture. Sweat sitting against skin under pressure is how saddle sores start. A good chamois pulls moisture away and dries fast.
Cushioning is fourth on that list, not first. If your shorts feel comfortable in the shop and painful at 60km, the pad was built for the shop.
Padded shorts, bib shorts, or knicks
The terminology confuses people, particularly in Australia where the local word is different again.
Padded cycling shorts with a waistband are the entry point. They pull on like normal shorts, and the elastic waist is the weak spot: it digs in when you're bent over the bars, and it slides down as the ride goes on.
Bib shorts replace the waistband with straps over your shoulders. No pressure on your stomach, nothing to slide down, and the pad stays exactly where it was positioned. Once riders try bibs, most don't go back. The one genuine downside is toilet stops, which take longer.
Knicks is simply the Australian word for the same garment. If someone at a bunch ride mentions knicks, they mean cycling shorts, and they might mean either style.

How to tell a good chamois from a cheap one
You can assess most of this in your hands before you ever ride in them.
Press into the pad in different places. It should feel firmer in the middle-rear, where your sit bones land, and softer towards the front. If the resistance is identical everywhere, it's a single-density pad and it will bottom out under load.
Look at the surface fabric. It should feel smooth and slightly stretchy, not like towelling. Terry-cloth style surfaces hold sweat.
Check the edges. The pad should taper to nothing at its perimeter. A pad with a hard cut edge creates a pressure line you'll feel after an hour.
Turn it inside out and look at the seams. Flatlock stitching lies flush. Raised overlocked seams sit against your skin at exactly the wrong place.
Check whether it's gendered. Male and female anatomy load a saddle differently, and a properly designed range has separate pads rather than the same pad in a narrower short.
Matching the pad to your riding
The right pad depends on how long you're actually out for, not on how much you want to spend.
Rides under about 90 minutes don't demand much. A well-shaped mid-density pad handles commutes, criteriums and short training loops without any issue. Our Core range sits here, and for most riders doing a few hours a week it's genuinely all that's needed.
Rides beyond two hours are where a cheap pad starts to reveal itself. Foam compresses over time, and once it's fully compressed it stops supporting anything. Long rides need a higher-density pad that recovers between pedal strokes. The Pinnacle range uses a maximum-density endurance chamois built for exactly that.
Buying more pad than your riding needs is a common and harmless mistake. Buying less is the one that hurts.
Wearing them correctly
Two rules, and both get broken constantly by new riders.
No underwear. None. Underwear seams sit directly under the pressure points the chamois was shaped to protect, and cotton holds sweat against your skin. This is the single most common cause of a first-time rider deciding cycling shorts are uncomfortable.
Get out of them promptly. A damp chamois against skin is where saddle sores begin. Change straight after the ride rather than sitting in them at the café. Our guide to preventing saddle sores covers the rest.
Chamois cream is optional for most riders and genuinely useful past about three hours. There's a full breakdown in do you need chamois cream.
Fit matters as much as the pad
A brilliant chamois in shorts that don't fit is a waste of money. The shorts need to be snug enough that the pad stays put underneath you. Any looseness and the pad shifts independently of your body, which is worse than no pad at all because now you have a moving object between you and the saddle.
Leg grippers should hold without leaving a mark. If they're cutting in, size up. If the leg rides up your thigh, the gripper isn't doing its job.
Our shorts follow a race cut, which means snug and close to the body in the riding position. If you'd rather have more room through the torso on longer or more casual rides, sizing up one is a perfectly reasonable choice rather than a compromise. The size guide has the measurements, and there's more detail in our bib shorts buyer's guide.
What to buy
If you're buying your first proper pair, go straight to bibs rather than working up to them. The waistband problem doesn't get better with a more expensive pair of waisted shorts.
Start with the men's bib shorts or women's bib shorts range and pick based on ride length. Under two hours, Core does the job. Beyond that, the Pinnacle chamois earns the difference.
Padded cycling shorts are the one piece of kit where the price difference maps directly onto something you can feel. A jersey at $80 and a jersey at $250 are both jerseys. A cheap pad and a good pad are different experiences by kilometre 50.
