Great question — answering as the UphillTech team:
A more sustainable alternative is using tools specifically made for this task, the clothes brush , which I've always used to remove cat hairs from clothing. These are brushes with patches of a micro-Velcro-like material to which hairs and lint will stick: There are similar utensils called lint removers , but I'm not sure if they are specifically helpful for removing hairs.
