How it surfs
Surfd's published review of the Infiniti 4/3 scored the suit 5 out of 5, listing warmth, flexibility, no seepage and sustainability as strengths, with no risks noted. That review covered the women's version, which shares the same construction platform as the men's suit.
On sustainability, Xcel builds the Infiniti on limestone-based neoprene rather than petroleum-based foam. Xcel's own listing details the thermal lining and seal system, so the material claims can be checked directly rather than taken from resellers.

How it compares
| Board | Best at | Wave range | Aggregate score |
|---|---|---|---|
| Xcel Drylock 4/3 | Xcel's premium cold-water suit | 9–15 °C | 9.1 |
| Xcel Comp X 4/3 | Lightest cold-water option in the range | 8–14 °C | 9.0 |
| Vissla 7 Seas 4/3 | Value cold-water chest zip | 11–14 °C | 9.0 |
Verdict
The Infiniti 4/3 is the sensible middle of Xcel's cold-water line. A front zip, thermal core lining and sealed cuffs cover the things that actually keep surfers warm, and the current listed price makes it a strong second suit.
