Warmth for winter sessions. UPF 50+ coverage that goes where you go.
Early tee times. Cold track laps. Windy pickleball courts. The season changes, but your routine doesn’t.
Meet the Sparms ThermoTech Thermal Arm Sleeves: a lightweight warming layer made for winter movement, with UPF 50+ protection built in. They keep your arms comfortable when the air feels sharp, and they stay easy to wear when the effort ramps up.
Why thermal sleeves, instead of “more layers”
Bulky gear can mess with your swing, your stride, or your feel. ThermoTech sleeves are built to keep things simple:
-
Warmth without the weight
-
Stretch that moves with you
-
Breathable comfort when you start to sweat
-
UPF 50+ coverage for bright winter days
Winter sun is still sun
Cool temps can trick you into skipping protection. But UV doesn’t take the season off, especially when you’re outside for long sessions. ThermoTech gives you coverage that fits into your kit without changing your game.

How people wear them in winter
Golf
Ideal for early rounds when you want warmth without adding layers that interfere with your swing.
Running and training
Start warm, stay mobile, and stay comfortable through windy miles or outdoor circuits.
Pickleball and tennis
Great for crisp court sessions when you want coverage that doesn’t bunch or restrict.
Soccer and team sports
A smart warm-up layer for cold-start drills, sidelines, and morning training.
Everyday movement
Dog walks, commutes, weekend errands. If you’re outside, they fit the day.
The easiest way to layer
Think of ThermoTech sleeves as the “in-between” piece: more warmth than bare arms, less bulk than a jacket. Wear them under a short sleeve or hoodie, or pair them with other Sparms essentials for coverage that looks sharp and plays well.
Ready when you are
ThermoTech Sleeves are available in black and white, in multiple sizes. If winter is your season to stay consistent, ThermoTech is the layer that keeps your routine moving.
