Endura Skinsuits
When the clock starts, aerodynamic drag is the one thing standing between you and a personal best - and Endura skinsuits are engineered specifically to deal with it. Built around the brand's Drag2Zero (D2Z) wind tunnel collaboration, these suits strip away the bunching and overlapping fabric of a two-piece kit to let air move cleanly over your body. The watt savings are real, measurable, and repeatable.
Endura's race-wear draws on Silicone Surface Technology (SST) - chevron-pattern applications that manipulate the boundary layer of air across the suit's surface - alongside aero-specific chamois pads designed to stay flat and smooth under load. There's also a raw edge hem approach and encapsulator pockets for race numbers, details that matter when you're pinning on a number at 6am on a damp dual carriageway.
The range covers pure time trial and track suits through to road-racing options that hold up across a domestic crit season. Whether you're targeting a club 10 on a Tuesday evening or lining up for a regional road race, an Endura aero skinsuit closes the gap between your fitness and the clock. Fast, considered, and backed by proper engineering.

The Drag2Zero Advantage: Fabric Tech and How It Works
The D2Z name isn't just branding. Endura's Drag2Zero programme involves genuine wind tunnel testing to identify where drag is generated across a rider's body at race speed, then engineers the fabric placement and surface treatments to address those zones directly. SST - Silicone Surface Technology - is the headline application here: rows of raised silicone chevrons bonded to the suit's surface that trip the boundary layer of airflow, keeping it attached to the body for longer and reducing the drag penalty significantly compared to smooth fabrics.
The base fabrics themselves are high-stretch and moisture-wicking, which matters more than people give credit for. At threshold on a UK summer morning - dense, cool air, humidity that hasn't burned off yet - you need a suit that cuts through without turning into a sweat trap inside the first ten minutes. Endura's fabric choices handle both. On select panels, durable water repellency (DWR) treatment deals with road spray on wet circuits or exposed dual carriageways, so a damp start doesn't mean a soaked suit by the finish.
The fabrics also stay aerodynamically stable under load. A jersey billowing at the back or a chamois pad bunching under the sit bones both cost you watts. The integrated construction of an Endura aero skinsuit removes those variables entirely, and that's before the SST even enters the equation.
Fit, Range, and Choosing the Right Suit
Fit is where most people go wrong with skinsuits. Standing in a car park, a correctly sized Endura suit will feel restrictive across the shoulders - almost uncomfortably so. That's correct. The moment you drop into an aero tuck, the suit should pull smooth and wrinkle-free across every surface. Wrinkles are drag. If you're wavering between sizes, go smaller.
Within the range, the D2Z Encapsulator suits sit at the top end and are built for pure TT and track use. The integrated race-number pocket keeps fabric flat and avoids the drag penalty of a pinned number flapping at speed - a small detail that reflects how seriously Endura takes the aero brief on this one. The 1000 Series chamois pad in the flagship suits is denser and more supportive, suited to longer TT efforts where saddle comfort becomes a real factor.
The Pro SL road suits are shaped around crit racing and road racing rather than pure TT. The 700 Series chamois pad is lighter and less bulky, which works better for the varied positions and repeated standing efforts of a criterium. The fit is still aggressive - this isn't a sportive suit - but there's marginally more freedom through the shoulders for out-of-saddle efforts. If you race both formats across a season, the Pro SL is the more versatile call. If you're tunnel-focused on time trials, the D2Z Encapsulator is the dedicated tool.
Worth noting: if you're looking at multi-sport use with quick-drying chamois pads and tri-specific construction, that's a different conversation - head to our Endura Tri Clothing page for those options. The skinsuits here are road and track, full stop.
Pair any of these suits with the right support kit and the gains compound. Endura's aero overshoes continue the smooth surface down to the foot, and purpose-made Endura socks cut the gap between suit hem and shoe cleanly. An aero-optimised Endura helmet rounds out the setup - it's all engineered to work together rather than being a loose collection of fast-looking parts.
Layering, Washing, and Looking After Your Investment
Nothing goes under the chamois. That's non-negotiable - underwear under a pad causes chafing and saddle sores that will end your race season faster than any mechanical. The chamois is designed to work directly against skin, and that's the only way it functions properly.
For early-season UK time trials - those 7am events where the air is genuinely cold and standing around at sign-on is its own ordeal - a thin, close-fitting base layer under the top half of the suit is a reasonable call. It needs to be genuinely aero-focused, not a regular thermal layer. Bulk defeats the purpose. Keep it compressive, keep it thin, and make sure it doesn't bunch at the waist where it meets the suit's chamois section.
Care is straightforward but unforgiving if you cut corners. Wash at 30 degrees, always. Fabric softener is the enemy - it coats the fibres, kills the wicking properties, and degrades the silicone grippers on the raw edge hems that stop the suit riding up. Never tumble dry. The heat damages the elasticity and breaks down the SST applications over time. Hang the suit flat to dry, away from direct heat. Treat it carefully and it'll hold its shape and performance across a full season of racing.
The Endura road racing suit and Endura time trial suit options represent a meaningful investment, and the care routine is the simplest way to protect it. A skinsuit that's been tumble-dried twice won't fit or perform like a new one - and fit, as covered above, is everything.

Endura Skinsuits FAQs
How tight should an Endura skinsuit fit?
Tight enough to feel restrictive standing upright - that's normal and correct. When you're in an aggressive riding position, it should pull completely smooth with no wrinkles. Wrinkles create drag, so if you're between sizes, size down. A second-skin fit standing still means a perfectly contoured suit on the bike.
Do you wear anything under a cycling skinsuit?
Never wear underwear under the chamois pad - it causes chafing and saddle sores, full stop. In cold early-season conditions, a thin, compressive base layer under the top half is fine for UK time trials, but it needs to be genuinely close-fitting. Anything bulky undermines the aero advantage you're wearing the suit for.
Are skinsuits faster than a jersey and bib shorts?
Yes, measurably so. A two-piece kit creates overlapping fabric at the waist and sits further from the body - both of which cost you watts at race speed. Endura's wind-tunnel-tested suits eliminate those drag sources entirely. The SST surface treatment adds further drag reduction on top of the integrated construction benefits.
