Wax also improves durability though, so you may consider using it for that. Put it on the elbows for example.
>>1971052A membrane inbetween two fabrics that holds off liquid water but can be passed by water vapour. Thus the term waterproof-breathable. Works really well in some situations, has a few problems in practice:
-Breathability is limited
-It only works when there's a temperature/humidity gradient between inside and outside (i.e. in cold dry weather, when the outer shell fabric is dry). This is why the outer shell is always treated with a dwr, but those are limited (obviously... otherwise we wouldn't need the membrane in the first place)
