I recently brought one of these Henri Lloyd smocks and though I would post a review of it.
Henri Lloyd smock
It is a TP2 smock with hood and is from the new `05 range. It was initially brought with the intention of being used for foredeck duties as I needed something that was light and sealed at the neck and cuffs so I did not get totally soaked when the boat goes through a large wave. It features a neoprene sealed waist, latex seal around the neck and cuffs and a fleece lined collar. The addition of the fleece collar makes a huge difference compared to similar smocks I have used as it does not rub and irritate your neck after a few hours and it keeps you nicely warm. The seals all work well and the brightly coloured hood does come in useful when it starts to get really wet.

In summary it is a great buy for use on the foredeck or anywhere on the boat where you need a watertight jacket that does not restrict your movement but still provides a high degree of comfort and protection from the elements.
