The Aqualung FITFLEX Men's Jacket 3mm is one half of a two-piece scuba wetsuit system built for faster, easier kitting up. This page includes the jacket only; add the matching FITFLEX men's pants to complete the set. Super stretch neoprene, smooth skin sealing, and the FITFLEX connection system help limit flushing.
Complete the Two-Piece Wetsuit Set
This product page is for the jacket only. The FITFLEX is designed as a two-piece wetsuit, so the matching Aqualung FITFLEX Men's Pants 3mm must be purchased separately to complete the full set.
Product Overview
Kitting up for repeat dive days is simpler when the suit breaks into two pieces. This jacket is the upper piece of the FITFLEX set, and it is designed to connect securely to the matching pants so the complete wetsuit feels more controlled at the waist. That connection helps reduce water exchange and keeps the system seated properly while you move around the boat or gear up between dives.
Super stretch neoprene gives the jacket a soft, flexible feel that moves naturally with the body, while smooth skin seals support a better barrier where water is most likely to sneak in. The result is a practical warm-water wetsuit piece that balances comfort, convenience, and a clean-looking profile.
For divers comparing wetsuit options, the FITFLEX jacket is a smart fit for anyone who wants simpler changing and better sealing. Order the matching pants as the additional piece to complete the two-piece wetsuit set.

FAQ
The two-piece format breaks the suit into a jacket and matching pants, which makes changing faster and more practical between dive sessions. It is a simple way to reduce the effort of gearing up without giving up the benefits of a full wetsuit system.
The embossed connection between the jacket and pants is designed to keep the suit seated securely and limit flushing. That helps the suit feel more controlled at the waist and can improve comfort during repeated entries and exits.
The 3 mm FITFLEX jacket is aimed at warm-water and lighter thermal use. If you are planning colder-water dives, the right choice depends on your local conditions and layering preferences. If you want help deciding, email sales@bluewaterphotostore.com.
You can buy the jacket separately, but this page is for the jacket piece only. Add the matching pants page as the additional piece to complete the two-piece wetsuit set, so the connection system and sealing work together the way the suit was designed.
Yes. Start with the men's size guide above, then contact us if you are between sizes or need help matching the jacket to your body measurements. We can also help you coordinate the jacket with the matching pants at sales@bluewaterphotostore.com.
