A performance golf cap engineered for maximum comfort in warm conditions. The Under Armour Iso-Chill Drive Mid features Under Armour's signature Iso-Chill sweatband technology that actively disperses body heat, keeping you cool to the touch and focused on every shot. A modern square mid-crown silhouette sits slightly higher, just off the head, delivering a structured yet relaxed look — at home on the fairway or off the course. Stretch construction adapts naturally to your head shape, delivering all-day comfort with no adjustments required.
Under Armour's Iso-Chill technology works by flattening the fibers in the fabric to create a surface that draws heat away from your skin rapidly, making the material feel cool to the touch the moment you put it on. The Iso-Chill sweatband sits along your forehead — exactly where heat and sweat build up most during an active round — and continuously disperses that body heat so you stay comfortable from the first tee to the 18th green. Rather than simply wicking moisture, Iso-Chill actively regulates your perceived temperature, helping you stay calm, focused, and performing at maximum capacity even on the hottest summer days on the course. The result is a noticeably cooler wearing experience compared to standard golf headwear.
The front panel is constructed from a durable stretch fabric rated UPF 50+, blocking the vast majority of the sun's harmful ultraviolet rays — essential protection during long rounds in direct sunlight. This high sun-protection rating means you get meaningful defense against UV exposure while the fabric still maintains its soft, flexible character and does not add unwanted bulk or stiffness. Combined with the mid-crown profile and pre-curved visor, the cap provides broad-based coverage for your face and forehead, reducing both UV risk and glare. It is the kind of practical performance detail that lets you concentrate on your game rather than the elements.
The back and side panels are crafted from spacer mesh, a multi-layer breathable construction that allows warm air to escape from inside the cap while drawing in cooler air from outside. This all-around ventilation system works in tandem with the Iso-Chill sweatband to deliver a comprehensively cool microclimate around your head during physical activity. Unlike caps that rely on eyelets alone, the full-panel spacer mesh design maximizes the surface area for airflow, reducing heat build-up across the entire crown. The contrast between the structured stretch-fabric front and the open-weave mesh back also gives the cap a modern, sport-performance aesthetic.
Designed with a stretch-fit architecture, the Iso-Chill Drive Mid requires no external adjustment mechanism — no snapback, no velcro strap, no fitted sizing in the traditional sense. Instead, the elastane-blended fabric expands and contracts gently around your head, providing a snug yet pressure-free hold that stays in place during your swing without digging in. The mid-crown silhouette — a modern square profile that sits slightly higher and just off the head — delivers a contemporary look that bridges sport performance and everyday wearability. Whether you are walking 18 holes or heading for a post-round coffee, the fit adapts with you.
