The Ladies Packaway Overtrousers are waterproof, breathable & benefit from Isolite 5000 technology. Designed to fit comfortably over existing trousers, they pack into a small bag for easy storage. Ideal to be kept in the car for emergencies or in the bike saddle bag in case of rain. Boasting taped seams to keep you warmer & dryer, an elasticated waist gives a more comfortable fit & prevents the moisture from seeping in. There are press studs at the hem for ease of use & the trouser can be stored in the mesh stuff sack- supplied.
