Sondico Long Sleeved Core Base Layer Junior - Blue

A base layer is the first layer of clothing worn directly against the skin. Its primary function is to manage moisture by wicking sweat away from the body, helping to regulate body temperature and keep the wearer dry and comfortable during physical activity.

Yes, its design helps regulate body temperature. In warm weather, it wicks sweat to keep you cool and dry. In cold weather, it provides an insulating layer to help retain warmth when worn under other garments.

Optivent technology refers to the strategic placement of mesh panels, typically in high-sweat areas, to enhance breathability and airflow. This helps to dissipate heat and moisture more effectively, keeping you cooler and drier.

While it can be worn alone, it is primarily designed as a performance base layer to be worn underneath other sports apparel. Its snug fit and material are optimized for this purpose.

It is recommended to refer to the specific size chart provided by Sondico for junior sizing. A base layer should fit snugly but comfortably to maximize its wicking and support properties without restricting movement.

The shell is typically 92% Polyester and 8% Lycra (or 90% Polyester / 10% Lycra for Grey Marl variants). The mesh panels are 82% Polyester and 18% Elastane. This blend provides durability, stretch, and moisture-wicking capabilities.

This is a standard safety warning for garments made from synthetic materials like polyester. While durable, these fabrics can be flammable and should be kept away from open flames or high heat sources.

Ensure the base layer is the correct size – too small can cause compression issues, too large can bunch. Also, ensure the garment is clean and free of detergent residue by rinsing thoroughly during washing. The flat lock seams are designed to prevent irritation, so check for any manufacturing defects if irritation persists.

Wash the base layer promptly after each use to prevent sweat and bacteria buildup. Use a sports-specific detergent designed for synthetic fabrics, which can help eliminate odors effectively. Ensure the garment is fully dry before storing.

Check if the garment size is appropriate for the wearer's current measurements. Over time, frequent washing or high-heat drying can affect the elasticity of the hem. Always follow the recommended care instructions, especially regarding drying temperature, to preserve elasticity.
