Why choose Instinct Trail Arm Sleeves?

If you are looking for arm warmers with maximum function in minimal form , this is the obvious choice. They combine ergonomics, durability and technical performance , developed by a brand with roots in alpine racing environments.

Instinct Trail Arm Sleeves are seamless unisex arm warmers with a stretchy fit. They are designed to fit snugly and follow the movement of the arm without sliding down, cutting in or restricting blood circulation.

Sizes

Instinct Trail offers the model in two combined sizes but does not publish a separate size chart with exact arm circumferences in centimeters. Therefore, use your normal size for body-hugging workout clothes as a basis.

How to measure your arm

If you want to check the fit, you can measure:

1. Upper arm: Measure around the widest part of the upper arm with the arm relaxed.
2. Forearm: Measure around the widest part of the forearm.
3. Arm length: Measure from just below the armpit to the wrist.

Hold the measuring tape close to your skin without pulling it too tight. It is best to measure both arms and start from the larger one.

What size should I choose?

• Choose S/M if you normally wear S or M and have narrow to normal-sized arms.
• Choose L/XL if you normally wear L or XL, have thicker upper arms or prefer less compression.
• If you are between M and L, L/XL is normally recommended.
• If you have size M but thick upper arms, L/XL may provide better comfort.
• If you have size L but very narrow arms, S/M may provide a more stable grip, provided the sleeves do not feel restrictive.

Check the fit

The arm warmers should feel like a second layer of skin. They should stay in place as you bend and stretch your arms, but not cause numbness, tingling, or obvious pressure marks.

• If the sleeves slide down, the size is probably too big.
• If they cut in or restrict movement, the size is too small.
• The top edge should lie flat against the skin without rolling.
• Check the fit with both straight and bent arms.
