How we calculate scores →About this gear
The FLX Extreme is a polyester/butyl-rubber/polyester trilaminate drysuit with a thicker rubber layer than the TLS350 and Cordura overlays on the legs. Its diagonal front zip, telescopic torso and waist adjustment are intended to preserve movement while adding protection. DUI also offers an FLX HD fabric option, which should be specified separately.
Consider before buying
The 2019 ScubaLab test concerns the standard FLX Extreme construction, not the later HD option. Testers praised its trim, air control and unobtrusive seal rings, but those findings still depend on fit. Compare the exact zipper, seal, valve and boot package on your quotation with what was tested.
Our take
Put the standard FLX Extreme on your shortlist when you want more protective construction than the TLS350 without moving to crushed neoprene. Its published test feedback is useful, particularly for fit and air management, but no eligible numeric overall rating was established. Check valve access and knee movement with your real undergarment before deciding whether the extra material is worthwhile.
