The Xcel Men's Infiniti Hooded Full Wetsuit 5/4mm is engineered for surfers and water adventurers who refuse to let cold water win. Combining Thermo Dry Radiant heat-reflection technology, ultra-stretch Nanoprene Lite neoprene, and fully sealed seams, this suit delivers serious warmth without sacrificing movement. Whether you're chasing winter swells or exploring frigid coastlines, the Infiniti is built to keep you in the water longer.
Winter surfing has a way of sorting out the committed from the casual. When the crowds thin out, the swell picks up, and the water temperature drops into teeth-chattering territory, what you're wearing becomes everything. The Xcel Men's Infiniti Hooded Full Wetsuit 5/4mm is designed precisely for those sessions — the grey-sky mornings, the off-season missions, the days when most people stay onshore. Priced at USD $479.95, this suit sits at the premium end of the 5/4mm category, and it earns that positioning through a thoughtful combination of thermal technology, stretch performance, and durability. It's the kind of gear you buy once and rely on for seasons.
Warmth where it counts most
The standout feature of the Infiniti 5/4mm is its layered thermal system, which adapts to where your body needs protection most. Xcel uses two distinct interior technologies across the suit:
- Ultra Stretch Infrared (IR) upper interior — positioned across the torso and chest, this lightweight material generates warmth through far-infrared heat reflection, adding thermal efficiency without bulk.
- Thermo Dry Radiant (TDR) lower interior — running from chest to ankle, TDR uses a metallic lining beneath the textile to block external cold from penetrating while reflecting your body's own heat back inward.
The result is a consistent, enveloping warmth across the core — the area most critical for maintaining performance and comfort in cold water. This dual-zone approach is smarter than a one-size-fits-all liner, and it shows in how the suit feels after extended sessions.
The integrated hood adds a meaningful layer of coverage for the head and neck, areas that lose heat rapidly in cold conditions. For surfers paddling out in sub-10°C (50°F) water, the difference between a hooded and hood-free suit is felt almost immediately.
Stretch and mobility
Cold-water suits have historically come with a trade-off: warmth in exchange for movement. The Infiniti challenges that compromise through its use of Nanoprene Lite, a Japanese limestone-based neoprene that delivers a softer, lighter feel compared to petroleum-based alternatives. The material is inherently more flexible, which makes a tangible difference during paddle-outs and dynamic surfing.
The exterior is covered in Xcel's All New Channel Flex technology, a material construction engineered for greater stretch in all directions. The channel-patterned surface reduces resistance during arm extension and torso rotation — two movements surfers make hundreds of times per session.
The one-piece front-and-back panel design minimizes seams across the core, further reducing restriction and the potential for pressure points during paddling. For surfers who've worn older or entry-level thick suits and know that "straitjacket" feeling, this construction is a genuine improvement.
Construction and durability
A wetsuit's thermal performance is only as good as its seam integrity. Water intrusion through stitching is one of the primary sources of cold in the water, and the Infiniti addresses this directly:
- Triple-glued and blind stitched seams throughout the suit
- Reinforced Fusion X taped seams at high-stress zones for added durability
- Semi-dry zipper with snap closure to reduce water entry at the back
- Glide skin collar for a soft, sealing fit around the neck
The suit also incorporates dope-dye yarn and water-based glue in its construction — environmentally conscious material choices that reduce the suit's overall impact without compromising performance. For an audience that cares about sustainability alongside function, these details matter.

Who it's for — and who might look elsewhere
The Infiniti Hooded 5/4mm is an excellent choice for dedicated surfers who regularly paddle out in cold conditions, whether that means West Coast winters, North Atlantic swells, or year-round surfing in higher latitudes. The integrated hood, sealed seams, and layered thermal system make it well-suited for water temperatures roughly between 7°C and 13°C (45°F to 55°F).
Where it excels:
- Cold-water surfers who need reliable core warmth over multiple sessions
- Surfers prioritizing freedom of movement in a thick suit
- Buyers who value eco-conscious construction materials
- Those wanting a single integrated hood rather than a separate accessory
Worth considering before you buy:
- At USD $479.95, it's a significant investment — budget-conscious buyers may find comparable warmth at a lower price point elsewhere
- Surfers primarily in mild or warm water (above 15°C / 59°F) will find the 5/4mm suit too much for the conditions
- Some experienced cold-water surfers prefer the adjustability of a separate hood
The verdict
The Xcel Infiniti Hooded Full Wetsuit 5/4mm is a purpose-built cold-water tool, refined through Xcel's deep experience in performance wetsuit design. The combination of TDR heat reflection, Channel Flex stretch, and fully sealed construction addresses the real demands of winter surfing without sacrificing mobility for warmth.
For surfers who take their cold-water sessions seriously, this suit earns its price tag. It's dependable, well-constructed, and engineered with genuine attention to how surfers actually move in the water. Buy it for the shoulder season. Wear it all winter.
