The Australian Heat Gear Guide · ATGATT at 40°C
When it hits 40 degrees the temptation is to strip the gear off. That is exactly the wrong move - and it is not the only option. Here is how to ride cool without riding unprotected, and the mesh, base layers and cooling kit that make it work.
The squid season
More bikes are out, more skin is showing, and the surface you would slide across is hotter and harder than ever.
Summer is the season riders talk themselves out of gear. The jacket feels like a sauna at the lights, the armour is sweaty, and a t-shirt is right there. The problem is that heat changes how you feel, not what happens in a crash. Bitumen at road speed takes skin off in under a second, and it does that whether it is 15 degrees or 40.
There is a second, quieter risk. Heat stress builds while you ride - dehydration and a rising core temperature chip away at concentration and reaction time long before you feel genuinely unwell. So the hot day is the one where the least gear is worn, the most riders are out, and the rider is least sharp. That is not an argument for suffering in a winter jacket. It is an argument for gear that is built to breathe.
The fix is not to accept bare arms as the price of staying cool. It is to change what "gear" means in summer - airflow where you need it, protection that stays put, and a couple of cheap tricks that make a hot commute genuinely comfortable. The rest of this guide is how.
The four levers
Comfort in the heat comes down to four things - and only one of them is "less fabric".
Airflow. Moving air over damp skin is what cools you. Mesh and perforated panels let the wind do the work, which is why a well-vented jacket can feel cooler than bare arms baking in direct sun.
Moisture management. A moisture-wicking base layer pulls sweat off your skin so it can evaporate instead of pooling. Dry skin cools; wet, trapped skin cooks.
Heat reflection. Lighter colours and less sun-soaking material keep radiant heat down. Black leather in direct summer sun is its own kind of oven.
Hydration. Wind dries your sweat before you notice it, so dehydration sneaks up on riders. Drink before you are thirsty - a dehydrated rider makes slower decisions, and that is a safety issue, not just comfort.
MotoCAP scores every jacket it tests for breathability on an independent five-star scale - a measured read on how well a garment sheds heat and moisture, kept completely separate from its protection score. It is the closest thing to an honest cool-factor rating that is not marketing. We break down how it works in the MotoCAP report.
The airflow tradeoff
More airflow usually means a little less abrasion time. None of it touches your armour. Match the jacket to how and where you actually ride.
Airflow is a property of the shell. The CE-rated impact protectors at your shoulders, elbows, back, hips and knees work exactly the same in a mesh jacket as a winter one - and they are the same parts you can upgrade. More on that in CE ratings explained.
Wear the armour, not the bulk
The coolest way to stay protected is to move the protection onto your body and keep the outer light.
An armoured base layer carries CE protectors against your skin under a light shirt or mesh jacket, so you stay covered even when you would rather not wear much. Add a moisture-wicking base, a well-vented outer and a damp neck gaiter, keep water within reach, and you have a setup that reads the heat instead of surrendering to it.
Our pick for the base layer is the Pando Skin UH AAA - the same MotoCAP-topping armoured legging we point riders to year-round, shown below alongside the rest of a heat-ready kit.

Cool and covered
A shortlist of ventilated jackets, armoured base layers and cooling kit our riders actually buy - swipe through the lot. Prices and stock pull in live.
A lightweight women's summer jacket with polyester mesh panels front, back and inner arms for full airflow, over abrasion-resistant 600D and SEESMART CE Level 1 armour at the shoulders and elbows. Prepped for a CE Level 2 back protector.
One of the lightest jackets we stock - ultra-thin, highly ventilated mesh with CE Level 1 shoulder and elbow armour. Folds down to almost nothing and built for hot, humid riding.
Urbane Pro® Mk3 - Women's Body Armoured Shirt
A CE Class AA armoured shirt certified for both impact and abrasion, so it can be worn on its own without an outer shell. Breathable arrownet mesh with Level 2 armour at the back, shoulders and elbows - a genuine summer game-changer.
Skin UH AAA - Unisex Armoured Leggings
MotoCAP's best textile pants of 2025 and the coolest way to carry armour - three protection stars worn alone, four under a normal pair of jeans. CE protection without a hot second layer.
A light, stretchy women's jacket in MotoGirl's breathable Sherrie fabric, with the armour barely noticeable. For riders who want a summer jacket that does not feel like one.
Urbane Pro® Mk3 - Men's Body Armoured Shirt
The men's cut of Knox's CE AA armoured shirt - impact and abrasion certified to wear on its own. Lightweight, breathable mesh with Level 2 armour where it counts.
A Dryarn base-layer shirt that wicks sweat and lets it evaporate to keep you cool, and stops your jacket sticking to your skin on a hot day. The layer that makes everything above it more comfortable.
Airy is not the same as safe. Everything we call heat-ready still has to earn it: CE-rated armour at the shoulders and elbows, abrasion-resistant panels where you would hit the road, and honest airflow rather than just a lightweight feel. Where MotoCAP has tested a garment for breathability we will pull the score up with you - and because mesh trades some abrasion time for airflow, we match the jacket to how and where you ride.

Straight answers
Not safely. Air temperature does not change how a road surface removes skin in a slide - a t-shirt gives you no abrasion protection at any speed. The cooler answer is gear built to breathe: a mesh or perforated jacket with CE armour lets air through while still covering you, so you keep the protection and lose very little comfort.
A good one is. Mesh trades some abrasion time for airflow, so what matters is the rest of the build - a CE rating under EN 17092, armour at the shoulders and elbows, and reinforced panels at the high-wear zones. A CE AA mesh jacket like the MotoGirl Jodie is genuine protective gear, not a fashion piece. Check the CE tag and, where available, the MotoCAP score.
The best one is the most ventilated jacket you will still wear every ride, with CE armour and abrasion cover to match your speeds. For stop-start city heat, a mesh jacket moves the most air; for faster highway work, perforated leather or textile keeps more abrasion time. Where MotoCAP has tested a jacket, its breathability star rating is the most honest cool-factor guide there is.
Yes, through evaporation. Wetting a neck gaiter or a cooling vest and letting airflow pass over it pulls heat away as the water evaporates - most effective at road speed with air moving through your gear. It is simple, cheap and genuinely effective on a hot commute.
They move the protection onto your body so the outer layer can be lighter. A CE-armoured base layer worn under a light shirt or mesh jacket keeps impact protection at the hips, knees, shoulders or back without a hot, bulky outer. It is the coolest way to stay covered - browse our armoured base layers.
They still matter - hands and feet hit the ground first. Perforated summer gloves and ventilated or mesh-panelled pants exist for exactly this, giving airflow without leaving those zones bare. Riding in shorts or joggers on a hot day is the same gamble as the bare-arms t-shirt, just lower down.
How we keep this accurate: gear availability and any MotoCAP breathability figures were checked as at 6 August 2026. We confirm current stock and the published rating before recommending a product. Source: motocap.com.au. This guide is general information, not personal safety advice.
Book a fit consultation or drop into our Melbourne or Brisbane shop. We will match a ventilated, CE-rated setup to how you ride - and make sure staying cool never means going unprotected.
