As with as all the Yak PFD's the Tahu is very comfortable to wear, and unlike some other touring PFD's isnt too long in the body so it doesn't ride up when your sitting in your boat. The side entry takes a bit of getting used to but shouldnt put you off especially if you wear a dry suit.  Loads of features and a comparatively large hydration pocket at 3ltrs make this a very popular jacket.  

What they say :

3D Supersoft PVC foam shape ensures maximum comfort

Side zip entry 

Expanding front pocket and knife pocket for additional storage

Vertical back pocket that holds up to 3ltr hydration pack

Bright colour and reflective piping for excellent visibility
