Careful with sizing.
These are super light, durable and pack down small. However the sizing seems to run pretty small. I'm 5'10 and usually a medium in everything but these were super tight! I would recommend either sizing up or buying two sizes and returning the one that doesn't fit.
Perfect just in case protection
The light weight and tiny packed size of these is the main appeal. Only slight quibble is the ankle zips being about 2 cm longer would make them easier to get on over boots in a hurry.
Pretty much perfect. Expensive but worth the money. Kept me dry and were surprisingly breathable .
