It's always advisable to keep your expensive outdoor gear protected with some sort of waterproofing treatment, and to make sure it's cleaned and maintained properly to ensure it lives a long and healthy life. If you want to do this without the use of nasty chemicals then you should choose one of the many products in the Granger's range. Established in 1937 they were one of the first companies to use eco-friendly water based waterproofing, and none of their sprays use aerosols. They have a wide range of treatments to restore and protect your footwear, clothing and equipment, including soft shell waterproofer, leather conditioner, and odour eliminators. Prices start at around £5.

Dear Elisa,
You've been had!
None of their sprays use aerosols?! Have you seen their website. YES THEY DO MAKE AEROSOLS. And Fabsil which is chock full of flammable solvents. If you want something environmentally friendly - try Nikwax
