Cool-Comfort Systems: Helmets and Harnesses That Breathe

Choose a helmet with generous vents and a light exterior color to reflect radiant heat. Full-coverage shells still matter for rockfall, but well-placed cutouts keep air moving. Store the helmet in shade, not on baking stone, and check suspension pads for salt-crusted wear.

Cool-Comfort Systems: Helmets and Harnesses That Breathe

Modern harnesses use airy foams and mesh that wick sweat, dry fast, and reduce hot spots on long belays. Try adjustable leg loops for swollen summer calves, and avoid overstuffing gear loops to maintain airflow. Inspect tie-in points frequently—sweat, dust, and repeated falls accelerate abrasion.

Ropes and Draws in the Heat: Handling, UV, and Drag

Warm temperatures soften sheaths slightly, so thin cords may feel extra supple—and extra quick through devices. Use a rope bag with a tarp to guard against UV, grit, and cactus spines. Rotate ends to disperse wear, and retire sun-faded cords sooner rather than later.

Ropes and Draws in the Heat: Handling, UV, and Drag

Wiregates shed heat and reduce gate flutter, while longer alpine draws cut drag on wandering lines. Keep draws shaded when possible; metal left in full sun gets surprisingly hot. Check dogbones for stiff salt buildup from sweat and dust; rinse and air-dry after long trips.

Footwork for Hot Rock: Shoes, Socks, and Approaches

Rubber Temperature and Shoe Storage

Different rubbers behave differently as temperatures rise. Keep shoes shaded to avoid mushy edges, and avoid leaving them on sunbaked rock. If your feet swell, consider a half-size tweak or thinner socks for approaches, then unlace quickly to cool between burns.

Approach Shoes, Moisture Management, and Thin Merino

Breathable uppers paired with thin merino socks resist blisters better than cotton. A short gaiter keeps scree and goatheads out, which reduces friction. After the approach, air your feet, replace damp socks, and powder heels lightly to maintain friction and morale for the crux.

Early Starts, Happy Feet

We once started at noon and paid with blisters and greasy rubber. The next day, a dawn alarm, dry socks mid-route, and shaded rests changed everything. What’s your best early-start ritual? Drop it in the comments—and follow us for weekly heat-beating strategies.

Hydration and Sun Strategy: Bottles, Filters, and UPF

For multipitch, stash a soft flask in the second’s chest pocket for quick sips at belays. Mix electrolytes to replace salt lost to relentless sweat, especially in dry winds. Avoid overdrinking plain water; balance intake with regular salty snacks to maintain performance.

Hardware Heat Management: Belay, Rappel, and Anchors

Assisted-braking devices help with slick, warm ropes, but remember that long rappels generate heat. Wear thin belay gloves to protect skin and improve grip on fire-warm hardware. Test lowering friction with carabiner orientation changes before committing to a long, exposed descent.

Hardware Heat Management: Belay, Rappel, and Anchors

Aluminum carabiners heat quickly; steel stays cooler but adds weight. Keep anchor lockers in the shade when possible, and avoid black anodized gear baking on route. Use auto-lockers for anchors to reduce fumbling when sweaty hands and sunscreen meet thin gate knurling.

Pack Light, Pack Right: Organization and First Aid

Choose a ventilated back panel and stash the helmet outside to dry on the hike. A rope bag with an integrated tarp speeds transitions and keeps dust off. Keep sunscreen, snacks, and tape in the top pocket for fast access between burns.

Pack Light, Pack Right: Organization and First Aid

Color-code slings and lockers to reduce rummaging in the heat. A tiny drybag protects phone, keys, and route notes from sweat and sudden storms. Bring a headlamp even on short days; summer thunderheads and slow parties still surprise, especially on multipitch linkups.

Skin, Chalk, and Recovery: Grip That Survives the Heat

Start with a thin base layer of liquid chalk, then top up with a loose blend that matches humidity. Some crags ban rosin, so check rules. Keep your chalk bag shaded, and brush holds lightly to avoid polishing in hot, glassy conditions.
