The 3/4-length Helter Skelter shorts are waterproof, but not really designed for planned wet rides – they're more for changeable weather days.
The waterproof Hydrofoil shell shorts roll up into their own zip rear pocket, so they're ideal for storing at the bottom of your riding pack for deployment as an over-layer.
You could go with just a liner underneath, but the fabric feels a bit odd so they're better over other shorts. If it’s raining you probably ought to opt for something like the Altura Attacks, which are waterproof riding shorts rather than waterproof over-shorts.
