Rab Sonic Tee - Regular - XL

The Rab Sonic Tee is optimized for warmer conditions due to its lightweight and breathable fabric. For cold weather, it serves best as a base layer, and you will need to add insulating layers on top.

Thanks to the odor control treatment and moisture-wicking properties, many users find they can wear it for 3-5 days or more on multi-day trips, depending on activity level and personal preference, before needing to wash it.

Dryflo™ Air is a specific fabric technology developed by Rab, designed to be extremely lightweight, highly breathable, and capable of rapidly moving moisture away from the skin to the fabric's surface where it can evaporate.

The Rab Sonic Tee weighs approximately 96g (3.4oz) for a size Medium.

The Sonic Tee is specifically engineered for high-output, warm-weather activities, emphasizing lightweight, breathability, and odor control. Other Rab tees might focus on different features like durability, insulation, or casual comfort.

Ensure the shirt is not too tight, which can restrict airflow. Wash the garment to remove any residues that might impede wicking. Verify you are in a temperature range where the fabric's intended performance is optimal.

Wash the garment with a technical fabric wash or a small amount of vinegar to fully strip residues that may be holding onto odors. Ensure proper washing and drying as per care instructions.

Though designed for comfort, individual sensitivity can vary. Ensure the garment is the correct size and not stretched too tightly across seams. Consider trying a different size or fit if irritation persists.
