Technology
Our neoprene wetsuits are conceived and designed in France, for water sports in all conditions: surfing, kitesurfing, windsurfing, wingfoil, sup...
We place great emphasis on product style, fit and finish. Every detail is considered to create the best-performing wetsuits.
Choosing the best materials
At Saint Jacques, you'll find 3 different materials to create versatile wetsuits. We choose the best thermal insulation to offer you top-of-the-range quality products.
YAMAMOTO LIMESTONE NEOPRENE
BIO II ™ THERMAL INSULATION
BIO-II ™ is 100% neoprene-free, and offers excellent performance in terms of flex, warmth and durability.
SUPERSTRETCH NEOPRENE LIMESTONE
You'll find it on our range of tops and back zip wetsuits.
Finishes for a technical wetsuit
GLUED SEAMS (GBS)
All our fullsuits have this finish, which guarantees optimum watertightness. The neoprene panels are glued and then stitched on the surface with a nylon thread without the needle piercing the neoprene (blin-stitch). This sewing system limits water ingress and provides a perfect finish.
BRAIDED SEAMS
The seams are braided on the inside to increase the wetsuit's waterproofing and durability. The braid is flexible and stretchable, so as not to "stiffen" and restrict freedom of movement.
All our fullsuits have this finish, except the BIO II range.
WARM QUICK DRY LINING
This inner lining increases warmth, speeds up drying time and provides extra softness. All our fullsuits feature this finish, which guarantees optimum watertightness.
Depending on the model, it extends from the chest to the knees or to the ankles. We use different linings for each model, always optimizing warmth and weight to match the suit's design.
WATER DRAINS
All our fullsuits feature an exclusive water drainage system at the ankles. Perforated neoprene drains water away from the leg and prevents water retention, ideal for wind sports such as kitesurfing, windsurfing and wing surfing. No need for Velcro.
ANKLE THREADING FINISH
Exclusive to Saint Jacques, inspired by classic sports joggers, to offer optimum comfort and support for the ankles. It also blocks water ingress at the bottom for windy sports.
ELASTIC BAND FOR KEYS
Very practical to avoid hiding your keys under the car ;) Depending on the model, a zippered pocket or elastic band on the inside of our wetsuits.
STRATEGIC REINFORCEMENTS
Thermo patch reinforcements are strategically placed to extend the life of your wetsuit. This finish is also found on all our fullsuits.
SILICON PRINT
All our wetsuits feature waterproof prints to block water ingress at the wrists. They are flexible enough not to interfere with donning and doffing.
KNEE REINFORCEMENTS
Zips adapted to wetsuit
CHEST ZIP
This system corresponds to a pre-engaged chest zip, offering greater freedom of movement and maximum waterproofing. Ultra-fast closure, even with gloves! You can find the chest zip on our latest 3/2mm wetsuit.
FRONT ZIP
This fully detachable chest zip offers easier donning than the chest zip. It also guarantees waterproofness and flexibility. You'll find this closure system on our BIO II collection, our Yamamoto fullsuit hooded convertible and our lisa Yamamoto integral, available in 3/2mm and 5/3mm.
BACK ZIP
YKK back zip closure with back panel system for easy donning, equipped with zip lining (back wash) for greater comfort and reduced water infiltration.
