Sorry, I just returned from the EDUI show in Rome. The suits are mostly the same, I will list the changes to the 2007:
Cosmetic is obvious
Trilastic stretch material added to underarm and side for flexibility and easier don/doff
Metal skin seals extended at wrist and ankle, can be rolled or trimmed as needed
Supratex added to shoulders for better abrasion resistance
Trilastic knee protection vs polyurathane, better flexibility with new pattern
Saphire plush lining, greater heat protection and more comfortable.
Those are the changes, the basics of the suit are unchanged, the features above are improvements.
Hope this helps.
Phil
