New to riding and trying to choose between a long‑sleeve and a short‑sleeve sun shirt? Here’s the clear, practical answer. You’ll learn what UPF means, how sleeve length changes comfort and protection, and exactly when to pick each style.
What is an equestrian sun shirt?
An equestrian sun shirt is a lightweight, breathable top designed for riding posture. It’s cut to allow reach to the reins without pulling at the shoulders, usually with a closer fit so it layers under vests. The fabric is quick‑drying and rated for UV protection (UPF). Compared with a regular T‑shirt, a purpose‑built riding shirt breathes better, avoids bulky seams under your safety gear, and stays more comfortable in the saddle.
UPF basics for riders
UPF (Ultraviolet Protection Factor) tells you how much UV a fabric lets through. As a rule of thumb, UPF 50 fabric blocks 49/50 of UV—blocking about 98%. More coverage plus a higher UPF number equals better protection.
Note two barn realities: wet or stretched fabric protects less because fibers open up; and you still need sunscreen on exposed skin like face, hands, and—if you wear short sleeves—your forearms.
When to choose equestrian short sleeved shirts
Pick short sleeves for shaded arenas, early morning/late afternoon rides, very humid days with little breeze, or if you simply run hot. You’ll get maximum airflow at the upper arms and a bit more freedom through the elbow crease. Balance the choice by adding sunscreen or detachable sun sleeves to cover forearms when the sun climbs.
When to choose equestrian long sleeved shirts
Choose long sleeves when you’ll be in direct sun, riding midday, or schooling over an hour. Coverage matters: sleeves shield forearms that often face the sun during flatwork and hacks. In light wind, a breathable long sleeve can actually feel cooler than bare skin because fabric shades the sun and helps sweat evaporate. The trade‑off is getting warmer when not moving; once you’re moving, airflow through technical knits will cool you down. Health authorities also recommend long sleeves and UPF‑labeled clothing for sustained outdoor activity.
Sun shirt fabrics & construction that actually help
Look for smooth, technical knits that wick sweat and dry fast. Dense, lighter‑weight synthetics often deliver better breathability per ounce than heavy cotton. Many riding tops add strategic ventilation zones (like underarm/upper‑back panels) and a higher collar to shade the neck.
Fit & sizing for the saddle
A sun shirt should allow a full reach to the mane without the shoulder seams biting. In two‑point, the hem shouldn’t creep and sleeves should still cover the wrist. Go true to size for airflow; overly tight tops reduce breathability and may stretch the fabric, which can lower UV protection.
Side‑by‑side comparison: Which sun shirt fits your ride?
A quick comparison to lock in your choice.
| Feature | Long Sleeve Sun Shirt | Short Sleeve Sun Shirt |
|---|---|---|
| Coverage | Full arm coverage; best for sustained sun. | Upper arm uncovered; requires sunscreen/sleeves. |
| Perceived cooling in sun | Often cooler in light wind due to shade + evaporation. | Feels airiest in still, humid air and deep shade. |
| Best for | UV index 7+, rides >60 minutes, clinics, hacks. | Shaded arenas, short sessions, early/late rides. |
| Layering | Works alone or under vests; more fabric at elbows. | Easy under layers; less elbow fabric. |
| Care notes | Keep dry between sets to maintain protection. | Remember sunscreen on forearms. |
Equestrian Sun Shirts FAQs
What UPF number should riders look for?
Aim for UPF 30+, with UPF 50 offering about 98% UV blocking. Higher coverage plus a higher number is your safest bet for long, sunny rides.
Do long sleeves actually feel cooler in heat?
Sometimes, yes. Shading your skin plus steady airflow helps sweat evaporate, which can feel cooler than bare skin in direct sun with a light breeze. In dead‑still humidity, short sleeves may feel better.
Do I still need sunscreen with a sun shirt?
Yes—for exposed areas: face, neck, hands, and (with short sleeves) forearms. Clothing is your base layer; sunscreen fills the gaps and covers where fabric ends.
Does wet or stretched fabric protect as well?
Not as well. When fabric gets wet or stretched, fibers open and let in more UV. Let shirts dry fully and avoid over‑stretching to keep protection consistent.
