TOP n°3 - Collab' x Monday in the Sun
Couldn't load pickup availability
Description
Our flagship piece among the tops. Certainly the most technical to design.
The cut :
- Removable foams.
- Extra soft lining.
- Adjustable back.
- Adjustable straps that can be fastened in 3 ways by an Italian knot system.
- No iron or plastic (let's avoid micro-waste) to adjust the straps but knots. The bows are small and pleasant to wear. As far as adjustment is concerned, the iron eyelets slide very poorly on swimwear materials and tend to loosen the straps too quickly; On the contrary, the bows do not loosen when you are in motion.
Ideal for a surfer or stand up paddler where the shoulders and arms are constantly under strain. Its elasticated finish guarantees a perfect fit. No underwire, this top can be worn under a neoprene suit.
Size advice:
This top runs a little larger than the others. If you hesitate between two sizes, take the size below. Find our equivalences.

Fabric & Care
Posidonie's goal is to use a fabric that helps clean the oceans and the environment, but is also very elegant and comfortable, freeing women from any movement constraints. An eco-responsible swimsuit is also a durable swimsuit, which is why I chose the highest range of European fabric made from waste such as fishing nets and plastic bottles. The fabric is slightly shaping and made to last.
Main fabric (Italy): 78% Recycled Polyamide. 22% Elastane.
Weight: 190gr.

Care instructions
The sea and salt do not alter your swimsuits if you rinse them with fresh water after each use. Let it dry flat or hanging by itself.
Wash your swimsuit by hand. You can machine wash it at the end of your vacation, on a delicate cycle (max. 30 degrees), with a small amount of non-detergent laundry soap, without spinning or drying cycles.
The chlorine resistance index of our materials is very good. However, the colors are more delicate.
