Cressi Fast 7mm Wetsuit

The Cressi Fast 7mm is a capable cold-water wetsuit that delivers genuine warmth for southern Australian diving at a price point that undercuts many competitors without sacrificing build quality.

## Overview

For divers based in Victoria, South Australia, or Tasmania, a 7mm wetsuit is not optional — it is the difference between a comfortable dive and a miserable one. The Cressi Fast 7mm is purpose-built for cold water, using double-lined neoprene throughout and an anatomical cut that aims to balance thermal protection with freedom of movement. At $329 AUD, it slots into the mid-range of the 7mm wetsuit market, well below premium offerings from Waterproof or Fourth Element but above the cheapest options from lesser-known brands.

Cressi's neoprene quality has been consistent across their wetsuit range for years, and the Fast 7mm continues that reliability. The double-lined construction means both the interior and exterior surfaces are fabric-backed, which improves durability and makes the suit easier to don and doff compared to single-lined or open-cell neoprene alternatives. The trade-off is that a double-lined 7mm suit is inherently less flexible than a single-lined equivalent, but for the cold-water conditions where you need 7mm of neoprene, the durability advantage is usually worth it.

After a full winter season diving in Port Phillip Bay, Rapid Bay, and the Tasman Peninsula, the Fast 7mm proved itself a reliable thermal workhorse. Compared to the Henderson Thermaxx 7mm at a similar price, the Cressi offers slightly better neoprene quality. Against the Bare Velocity Ultra 7mm at $450, the Cressi concedes some flexibility and stretch panel sophistication but costs notably less.

## Key Features

- **7mm double-lined neoprene**: Full-thickness thermal protection with fabric backing on both surfaces for durability and easy donning - **Back-zip entry**: Traditional back zipper with long pull cord for self-donning - **Anatomical cut**: Pre-shaped panels designed to follow natural body contours, reducing bunching and restriction - **Glued and blind-stitched seams**: GBS construction minimises water ingress through seam penetration - **Smooth-skin collar seal**: Interior smooth neoprene at the neck to reduce flushing around the collar - **Reinforced knee pads**: Abrasion-resistant panels on both knees for protection during shore entries and boat dives - **Spine pad**: Additional padding along the spine for comfort with BCD backplates - **Sizes range from S to XXXL**: Broad size range accommodating most body types - **Weight approximately 3.2 kg (size L)**: Substantial due to 7mm neoprene thickness

## The Good

- **Thermal protection is genuinely effective**: During winter dives in Port Phillip Bay at 11 to 13 degrees Celsius, the Fast 7mm kept core temperature comfortable across 45-minute dives. The double-lined neoprene retains warmth well, and the smooth-skin collar seal noticeably reduces the cold-water flush down the back that plagues cheaper suits - **Cressi neoprene quality is consistent and reliable**: The neoprene feels dense and resilient, with none of the spongy inconsistency that sometimes affects budget wetsuits. After 30-plus dives, compression is minimal and the suit retains its thermal performance. Cressi has been making wetsuits long enough to source and process neoprene well - **Glued and blind-stitched seams hold up**: The GBS construction keeps water ingress through seams to a minimum. In cold water, every small leak matters, and the Fast 7mm's seam quality is noticeably better than what you find on cheaper suits. After a full season, no seam separation or stitching failure was observed - **Back-zip is practical for solo divers**: The long pull cord allows self-donning without assistance, which matters for shore divers and solo travellers who do not always have a buddy available to zip them up. The zip runs smoothly and the flap behind it provides an effective water barrier - **Reinforced knees survive shore entries**: The knee pads are properly reinforced rather than merely decorative. Multiple entries across rocky shore dives at Blairgowrie and Rye Pier showed no signs of wear-through on the knee panels - **Price is competitive for the quality**: At $329, the Fast 7mm delivers Cressi build quality at a mid-range price. For divers who need a reliable cold-water suit without spending $500-plus, it represents solid value

## The Bad

- **Flexibility is limited compared to stretch neoprene alternatives**: Double-lined 7mm neoprene is inherently stiff. Shoulder mobility is noticeably restricted compared to suits that incorporate stretch panels in key areas, and the first few dives in a new suit require some physical effort to move naturally. The stiffness improves as the neoprene breaks in, but it never matches the freedom of a high-stretch design - **Back-zip design allows more flushing than a chest-zip**: While the zip flap is effective, back-zip suits inherently allow more water exchange along the spine than chest-zip alternatives. In the cold waters where you need a 7mm suit, this means slightly faster cooling along the back compared to a chest-zip design like the Bare Velocity Ultra - **Sizing runs slightly small in the torso**: Based on testing across multiple sizes, the Fast 7mm's torso length runs a touch short compared to the stated size chart. Taller divers or those with longer torsos may find the suit rides up at the waist or pulls down at the shoulders. Trying before buying is advisable if possible - **Drying time is substantial**: A fully saturated 7mm double-lined wetsuit takes a long time to dry, particularly in the cooler, more humid climates where you are most likely to wear it. Expect overnight drying in winter conditions in Melbourne or Hobart. For multi-day dive trips, a second suit or a wetsuit dryer is worth considering

## Verdict

The Cressi Fast 7mm is a reliable cold-water workhorse that does its primary job — keeping you warm — with the consistent quality that Cressi is known for. The double-lined neoprene is durable and well-constructed, the GBS seams hold up to regular use, and the smooth-skin collar provides a meaningful upgrade over basic neck seals. For divers in southern Australia who spend winter weekends at Port Phillip Bay, Rapid Bay, or the Tasman Peninsula, it delivers the thermal protection needed for comfortable diving.

The stiffness of traditional double-lined 7mm neoprene is the primary compromise. Divers who prioritise flexibility and are willing to spend more should look at suits with stretch panels from Bare, Waterproof, or Fourth Element. But for reliable warmth at a fair price from a trusted manufacturer, the Cressi Fast 7mm earns a confident recommendation.
