If a wetsuit doesn't fit properly you will compromise the warmth and comfort of your diving.
Fit is the key factor and normally you will find that the best fitting wetsuits are the ones that offer the most panels.
You should consider the grade and durability of the neoprene you are buying. Make sure the seams are glued, stitched and taped. The size of the zip (we recommend #10 YKK) and the durability of knee and shoulder pads are also important features.
