BOZ wetsuits.
Not that well known, but great suits.
Based on hearsay, their return and repair policy is great too include a knowledgable and helpful customer service staff.
Ive tried Billabong, Oneil, Rip Curl and Boz is the best ive seen.
Their prices are very reasonable compared to Excel or Hotline and as good if not better espescially their 5/4/3/ cold suits.
