Made of comfortable and high quality Jacquard woven fabric. These shoulder straps are designed in collaboration with illustrators from the awesome creative team at ILOVEDUST. ILOVEDUST is a celebrated and award-winning design collective from the UK that makes genuine design without compromise. Each Jacquard shoulder strap is tested to handle at least 90 kg. So no danger of it not supporting the weight of your Les Paul. Designed to be used with or without the Straplok Retainer System.
