FAQs

Does this garment provide compression?

Yes, this product is designed with a slim, ergonomic fit that acts as a base layer with compression characteristics.

Can I use fabric softener when washing?

No. Fabric softeners can break down the technical properties of the HeatGear® material and reduce its ability to wick sweat.

Is this suitable for outdoor summer training?

Absolutely. The HeatGear® technology and strategic mesh panels are specifically engineered to keep you cool and dry in warm conditions.

What should I do if the fit is too tight?

This item is designed for a slim, athletic fit. If you prefer a looser feel, you may want to consider sizing up, though this may impact the wicking efficiency.

Can I dry this in the sun?

While air drying is generally safe, it is recommended to tumble dry on low heat as per the care instructions to maintain material elasticity.

Troubleshooting

Fabric feels damp after long workouts

Ensure you are wearing the item as a base layer and avoid wearing heavy, non-breathable outer layers over it.

Visible signs of piling or fabric wear

Check if you are using fabric softeners or washing with rough garments like denim, which can degrade the synthetic fibers.
