2025 Thermal Reaction (Men's)

How to find your size

Men: The "T" (Tall) sizes add length across the torso, arms and legs. These sizes work best for a taller, lean body type.

Women: The "A" (Athena) sizes offer a larger size for a shorter frame, allowing women with more curves to comfortably find a good size.

If your height and weight do not correspond to one size, use these guidelines for sizing up or down:
If you're taller than the recommended sizes for your weight, choose the closest size based on height.
If you're shorter than the recommended sizes for your weight, choose the closest size based on weight.

COMFORT vs PERFORMANCE

Our wetsuits are meant to fit like a second skin aka tight. A performance fit will be compressive and tight and may feel uncomfortable on land. If you are near the top of a size recommendation and prefer a more comfortable fit, size up.

REACTION

If your height and weight fall right between two sizes we recommend sizing down as the added side flex and fit panels can make this suit feel roomier.

Alliance & Glide

The Alliance and Glide wetsuit do not come in every wetsuit size. If your recommended size is not listed, please choose the best size based on your weight. For the Alliance, if you are near the top of a recommended size, we recommend sizing up as the front zipper makes the suit feel tighter in the chest and can be more difficult to get on and off.
