The Solo Rain Coat isn't the most waterproof option you can buy but it's a good-looking top that can be stowed in a rear pocket and brought out in a shower or for extra windproofing in cold weather.
The catchily named Gore Xenon 2.0 AS Jacket is a lightweight, windproof and water-resistant jacket made from Gore's Windstopper Active Shell fabric.
When you don't need it the Xenon AS is airy light and packs down tight and small so it doesn't feel a burden in a rear pocket at all, happily taken along for just-in-case duties (so most rides then) without being a pain in the arse, literally, and when you suddenly do need it, it works.
The Protector Jacket is Ride's take on the race cape, an ideal garment for stuffing in your jersey pocket just in case of a shower or two.
Handmade from 100% polyester the construction and material is good quality. You get elasticated cuffs and waistband keeping the draughts out and a neat opening in the back to allow access to your jersey pockets underneath. A full zip makes getting it on an off a breeze and it easily scrunches down to jersey pocket size.
