SEAC Space 5mm Wetsuit

The SEAC Space 5mm is a sensible mid-range one-piece wetsuit that delivers good flexibility and solid construction at a price that does not sting, making it a practical choice for regular recreational divers across temperate Australia.

## Overview

SEAC's Space occupies the middle ground between budget suits that cut too many corners and premium suits that cost more than many divers can justify. At $205 AUD, it is priced to attract divers who have outgrown their first wetsuit and want something better without spending $500 or more. The ultraspan neoprene, pre-formed limbs, and reinforced high-wear areas suggest SEAC has thought carefully about where to spend the manufacturing budget and where to save.

After testing the Space across a range of typical Australian dive conditions — boat dives out of Nelson Bay, shore dives at Mornington Peninsula, and warm-water reef diving at the Solitary Islands — it proves to be a capable and honest mid-range suit. It will not dazzle you with the stretch of a $700 premium suit, but it will keep you warm, move reasonably well, and hold up to regular use without falling apart after one season.

## Key Features

- **Ultraspan neoprene**: A stretch-enhanced neoprene that offers improved flexibility over standard closed-cell neoprene without the cost of full ultrastretch formulations - **Pre-formed arms and legs**: Limbs are shaped during manufacturing to match a natural bent-arm, bent-knee diving position, reducing bunching and restriction underwater - **Back-zip entry**: Full-length rear zip for straightforward donning and doffing - **Reinforced seat and knees**: Additional material at the seat and knees for abrasion resistance during shore entries and boat diving - **5mm neoprene thickness**: Consistent 5mm across the suit for even insulation - **One-piece construction**: Single-suit simplicity with no jacket or long-john components to manage

## The Good

- **Strong value at the price**: At $205, the Space offers a genuine step up from budget suits without approaching premium territory. The ultraspan neoprene and pre-formed limbs are features typically found on suits costing $100 or more above this price point - **Pre-formed limbs make a real difference**: The shaped arms and legs reduce the bunching and pulling that flat-panel suits create when you bend your elbows or knees. Finning feels more natural, and reaching for gear or gauges involves less resistance. For a suit at this price, this is a welcome inclusion - **Ultraspan neoprene balances stretch and insulation**: The material is noticeably more flexible than standard neoprene, making the suit easier to put on and more comfortable during dives. It does not match true ultrastretch neoprene, but it represents a meaningful improvement over rigid budget alternatives - **Reinforced seat is a practical touch**: Many wetsuits reinforce the knees but ignore the seat, which takes significant abrasion from boat benches, rock ledges, and shore entries where you sit to put on fins. The Space's seat reinforcement is a small detail that extends the suit's usable life - **Straightforward one-piece simplicity**: No jacket to align, no long-john straps to adjust, no beaver tail to secure. You zip up and go. For divers who value quick gearing up on a busy charter boat, this simplicity has real appeal - **Adequate warmth for temperate conditions**: The 5mm thickness handles water temperatures from about 16 to 22 degrees comfortably. For typical diving conditions across the NSW coast, southern Queensland, and moderate Victorian conditions, the Space provides sufficient insulation for recreational dive durations

## The Bad

- **Seam construction is flatlock, not sealed**: At this price, the seams are flatlock stitched rather than glued and blind-stitched. This means water can seep through the needle holes, creating cold lines along the seams in cooler water. Below about 16 degrees, you will notice this, particularly on the inner thighs and along the sides - **Stretch is improved but not premium**: Ultraspan is better than standard neoprene, but it does not compare to the ultrastretch materials used in suits like the Mares Flexa. Divers who have worn a premium stretch suit will find the Space noticeably less flexible - **No infrared or thermal lining**: The interior is standard nylon-lined neoprene. There is no infrared reflective coating or plush thermal lining to supplement the neoprene's insulation. For warmer conditions this does not matter, but for cooler dives you are relying solely on the neoprene thickness for warmth - **Back-zip entry allows some flushing**: The rear zip does not include a gusseted flap or internal barrier. During entries and descents, water will enter along the zip line and flush through the suit until it equilibrates with body temperature. In warmer water this is brief and tolerable; in cooler water it is unpleasant - **Fit is standard rather than anatomical**: While the pre-formed limbs are welcome, the overall cut follows a fairly standard male pattern. Divers with proportions that differ significantly from the average — longer or shorter torsos, broader shoulders relative to waist — may find the fit compromised - **Limited colour and style options**: The Space comes in a utilitarian colour scheme that is functional but unremarkable. If aesthetics matter to you, options are few

## Verdict

The SEAC Space 5mm is a solid mid-range wetsuit that does what it should at a fair price. The pre-formed limbs and ultraspan neoprene lift it above budget territory, and the reinforced seat and knees show thoughtful design for the kind of diving most Australians actually do — shore entries over rocks, sitting on aluminium boat benches, and scrambling up ladders.

The flatlock seams and lack of thermal lining place a ceiling on its cold-water performance, so this is a suit best matched to temperate conditions above 16 degrees or warmer. For divers who are in the water one to three times a month across NSW, southern Queensland, or moderate Victorian conditions, the Space is an honest, capable suit that represents a smart use of your equipment budget. If you regularly dive below 16 degrees, look at suits with sealed seams and thermal linings, or consider supplementing the Space with a hooded vest.
