I use the Yak Descent and am happy out with it.
http://www.yak-paddling.com/pages/buoyancyaids.htm#Has 2 pockets. De wee pocket can take a knife, if needed, Ive my knife on my shoulder strap so use the pocket for a whistle, and spare contact lenses. In the big pocket I stuff in a sling, 2 prussick loops, a crab, a skullcap and a pulley.
Has done de job for 2 years far but I understand that it can be difficult to get Yak gear in Dublin.
Comes only in de non sinky colour of red
