KEY INFORMATION
MANERA SEAFARER GROMS FZ 5,4,3 MM - Children's Winter Fullsuit
What we like
- No compromises: Manera confirms that Groms suits incorporate the same materials and technologies as adult fullsuits.
- The warmest Groms fullsuit in the lineup features three thicknesses: 5, 4, and 3 mm. This matches the thickness of adult winter Seafarer fullsuits, letting young riders stay on the water all year round.
- Front zip: Chest entry, zip-free back for greater flexibility and reduced water entry.
- SFOAM foam: Made from limestone, Manera claims it offers the best flexibility, warmth, and durability ratio on the market.
- XTEND Fleece lining: Loops that insulate and retain warmth, soft against the skin, and quick-drying.
- SD2 Tape seams: Taped over 100% of the fullsuit, according to the FW27 book, for watertightness and long-lasting performance.
- 3D patterning: Manera designs its fullsuits in 3D before flattening them, creating a cut that follows the body without creases.

DETAILED DESCRIPTION
The Seafarer Groms in the Manera range
Manera extends its popular Seafarer range to children with the Groms line, available in three thicknesses: 5,4,3 mm for winter, 4.3 mm for mid-season, and 3.2 mm for summer. The brand emphasizes that they made no compromises. Groms fullsuits incorporate the same high-quality materials and technologies as the adult versions. Manera understands the importance of young riders feeling comfortable in the elements to foster their passion. GlissEvolution classifies this 5,4,3 mm fullsuit as the thickest of the three children's fullsuits.
A winter fullsuit for children
Manera designed the Groms with the same thickness distribution as their winter Seafarer fullsuits: 5, 4, and 3 mm. This thickness allows a child to comfortably join parents on the water even in the middle of winter. The XTEND Fleece lining dries quickly between sessions, and the taped seams effectively limit water entry. For use primarily in spring and autumn, the Groms 4.3 mm is sufficient.
The Seafarer FW27 construction
Manera summarizes the Seafarer as everything that makes a good wetsuit: warmth, comfort, durability, with the brand's cut and construction. It features SFOAM limestone-based foam, which Manera claims offers the best flexibility, warmth, and durability ratio on the market. The XTEND Fleece lining has loops that insulate and dry quickly. The XTEND jersey is soft and lightweight. SD2 Tape seams are used on 100% of the wetsuit, with a 3D-designed pattern and a water strainer to drain water.
The front zip
Entry is through the chest. The back remains entirely foam, making it flexible, and less water enters than with a back zip. Donning it requires a bit of practice the first two times; a parent nearby is sufficient, then the child can manage alone.
Choosing your size
Four sizes, named by age group: 8 to 9 years, 10 to 11 years, 12 to 13 years, and 14 to 15 years. The size guide higher on the page cross-references the child's height and weight, according to the Manera FW27 Groms chart, and that is what matters, not age. A child grows: between two sizes, choose the one that fits today; a wetsuit that is too large will let in water and will not keep them warm.

FAQ - MANERA SEAFARER GROMS FZ 5,4,3 MM
For children aged 8 to 15 who ride in winter, whether kitesurfing, wing foiling, surfing, or at sailing school. This is the thickest of the three Groms models. For mid-season, Manera offers the 4/3 mm, and for summer, the 3/2 mm.
The size guide above cross-references height and weight, based on the Groms Manera FW27 chart. A wetsuit should fit snugly when dry. If it's loose in the store, it will let water in when you're in the waves. If you have any doubt, visit the store. The sizes are in stock, or call us with your measurements.
That's what Manera states: same materials and technologies as the adult models, SFOAM foam, XTEND Fleece lining, SD2 Tape seams, and 3D pattern, in a child's cut and sizes.
No. They are chosen separately, depending on the season and water temperature.
