Sub-Woofer^® utilizes the performance fabrics and paneled design enjoyed in human-wear to maximize freedom of movement whilst keeping key joints and organs warm and regulating body temperature during periods of work and play in cool and wet conditions. The soft-shell fabric gives a good balance of warmth, protection from the elements, comfort and easy care. The Sub-Woofer® is designed for active dogs who like to get out and do their stuff whatever the weather.
