This is a Patagonia wetsuit for kids. The "R" mark is blue. The size is indicated as 4, but the specific age and detailed specifications are unknown. It is estimated to be for ages 4-6, but the total length is about 100cm, so is it for children around 120cm tall? I don't know the details. There are no major tears or noticeable stains, but there are creases from storage, and the rubber bond applied to the seams of each part has hardened and mostly fallen off. Outer material: Jersey Lining: Standard Thickness: ~3mm Gender: Kids Size: 4 Total length: 100cm Sleeve length: 65cm Body width: 40cm (80cm) Waist: 56cm Hips: 90cm Inseam: 68cm This is a wetsuit, so please consider these measurements as a reference only.
