What to Compare Before Buying
- Size: This set is size M. Compare that with the measurements you normally buy for base layers.
- Fit: The compression-style wording suggests a close fit, so check whether that is the feel you want from an underlayer.
- Layering: As a top-and-bottom set, it is meant to work under other clothing, so consider the outer layers you plan to wear over it.
- Activity use: It is described for running, cycling, hiking, football, golf and skiing, so choose it if that style of base layer matches your planned use.
Before You Decide
Check the size carefully, as this version is M. Confirm that you want a black top-and-bottom thermal set with a close-fitting base-layer feel, and make sure the long-sleeve style suits the layers you plan to wear over it.
