- Do these stay up while running?
- The silicone band at the upper edge is the grip point, and it is what keeps them from sliding down the arm. Pull them high enough that the band sits on the upper arm, not the forearm.
- How warm are they?
- They are a thin single-layer sleeve, so they suit cool mornings, start lines and windy stretches. They are not a winter layer; for cold-weather training look at fleece-lined or thermal arm warmers.
- What size should I pick?
- Sizing runs in broad bands from small to large. Measure your upper arm circumference and pick the band that covers it, since the silicone grip only works if the top edge fits snugly.
- Can I take them off during a race?
- Yes. They pull off over the hand and roll down small enough to tuck into a waistband or pocket. That is the main reason runners wear arm warmers instead of a long-sleeve top.
- Are they machine washable?
- Wash them cold on a gentle cycle and air dry to protect the silicone band and the print. Avoid fabric softener and high dryer heat.
- Are they unisex?
- Yes, they are cut as a unisex sleeve and sized by arm measurement rather than by gender.
