The SEAC Alga is, among wetsuits, the newest addition to the 2025 catalog from SEAC.
The Italian brand, after introducing to the market the innovative livery of the SEAC Snake, which resembled the scales of a snake, hits us again. A camouflage wetsuit, the SEAC Alga precisely, with striking camouflage is introduced in this year’s catalog.

The livery of this wetsuit, optimized for seafloors covered with algae, but capable of blending in on the vast majority environments, was computer-processed using the latest Artificial Intelligence techniques. We analyzed in X-Ray the 5 mm version sent to us as a world premiere by SEAC. Let’s discover together the features of this wetsuit.
Offer and price
From 2025 catalog of SEAC, we find that the SEAC Alga wetsuit, in the two-piece hooded jacket and high-waisted pants, is offered in 3 mm and 5 mm thicknesses.
There is no specifically female model in the catalog, as we have seen in the case of the SEAC Snake. The Alga, therefore, must be classified as a unisex model.
The sizes that can be purchased, however, range from S to triple XL (XXXL). Men and women of all body types will therefore be able to find the size that best suits their physique.
SEAC Alga is sold at a price ranging between €85 and €95 (for the pants) and between €104 and €115 for the jacket.
An absolutely competitive price for a wetsuit, certainly innovative and well-made, that wants to fit into a more entry-level market segment than the Snake model that represents the top of the range.
Pants and jacket can be purchased separately, thus combining, according to personal needs, sizes and/or thicknesses.

Materials
The SEAC Alga wetsuit is made of lined neoprene on the outside and open cell on the inside.
The neoprene on the outside is lined with Lycra. The lining appears very soft and does not stiffen the wetsuit, which is very stretchy in all directions.
The various “patches” that make up the wetsuit are joined, together, by bonding and Blind Stitch seams. Blind Stitch seams are non-passing seams that do not stiffen the parts and prevent abrasions on the diver’s skin. The SEAC Alga wetsuit has reinforcements on the sternum – designed for sling spearguns loading – and on the knees to protect against abrasions. These reinforcements are made with PU-print (Three-Dimensional Polyuteran Printing) technology. The reinforcements are designed in a segmented manner so as not to stiffen the protected parts too much. In particular, at the knee level, mobility is not compromised in the slightest.

The contours of the face, wrists, and ankles are bounded by the Aquastop System: an edging designed and constructed to limit the entry and exchange of water between the wetsuit and the diver’s body. This reduces cold water infiltration and minimizes body heat loss. We note that these profiles do not have the smooth material edging that we had so appreciated in the Snake model for its sealing capabilities. As described on the manufacturer’s website, the Lycra reinforcement, used as edging, certainly improves the strength. Such edging is more robust to both mechanical stress and the action of sun and salt water. Upon hearing from the parent company, we are confirmed that this choice is also related to the market positioning of the wetsuit (positioning versus price).
Quality Certification
Also in the case of SEAC Alga, there is a CE 14225-1 quality certification. This UNI-EN standard guarantees the wetsuit’s thermal performance. The characteristics are listed inside the wetsuit, printed on the open cell neoprene.
In the 5-mm model in our possession, class B, for water temperature ranges between 10°C and 18°C, and class C, for temperatures between 16°C and 24°C, are indicated.

Sternal reinforcement and kneeprotection
As mentioned, the sternum part, typically used to cock the sling spearguns, features PU printing.

The sternal reinforcement is generously padded but still very soft. The size seems to us to be adequate for the various loading habits of the arbalète. Very neat and finished is the perimeter seam that secures the chest protector. Despite the importance of the size of the reinforcement, the elasticity of the jacket in an area critical for diaphragmatic and thoracic extension during breathing does not seem compromised.

The knee protection is also made with the same polyurethane printing technology. The various segments that make up this print are evidently designed not to affect the knee joint. The protection covers a wide region and provides protection against abrasion of the entire area.
Unlike the sternal patch, there are no perimeter seams.
Cutting and stitching SEAC Alga
SEAC Alga wetsuit, consists of two pieces, with high-waisted pants and jacket with snap closure by “buttons.” The various parts are joined by BlindStitch bonding and stitching. This technique provides strength, better thermal insulation and, at the same time, limits rubbing of the seams on the diver’s skin.

The beaver tail and the fastening part of it are made of double-lined neoprene. In addition to the edges of the face, wrists and ankles, the lower edges of the jacket are also made of lycra. The number of “pieces” that make up the wetsuit is reduced thus contributing to the elasticity of the wetsuit and reducing the number of gluing and seams.
SEAC Seaweed Mimicry
Certainly it is the very unique camouflage that characterizes the SEAC Alga wetsuit. But to this, by now, SEAC has accustomed us.
The continuous motif that characterizes this outer liner clearly does not reproduce, in a photographic way, a particular seabed, but reminds us, evidently, of the floating of algae.
As indicated by SEAC’s own house, this camouflage is designed to adapt to a wide range of types of marine environments and, in particular, those in which there is denser vegetation.

The camouflage of the SEAC Alga, as reported by the Ligurian brand, is the result of optimization work, using Artificial Intelligence techniques, by a leading Italian design studio. The resulting pattern is one that best fits and blends with most marine environments.
The pattern reproduced on the wetsuit contrasts the continuity of the wavy black stripes with nuances, or shades, that are developed over two main bands of color: the one that precisely runs from black to brown and the one that fades from yellow-green into the palest blue.

The effect of image decomposition is enhanced not only by the shading but also by the varying distance between adjacent black lines. Looking at it as a whole, the pattern reproduced on this wetsuit generates an effect of different depth of parts. We are really curious to see how it will perform in the water.
Overall, a product that we felt was really well made. The material appears to be of excellent quality and the quality certification assures us of the thermal properties once worn. Definitely particular and original is the camouflage optimized to better adapt to the most diverse backdrops, thanks to processing techniques based on Artificial Intelligence that make this product a real innovation.
