Kids Swim Trunks Buying Guide
Q: What is the most suitable length for children’s swimming trunks?
A: SWIM BOTTOM的長度選擇主要取決於使用場合。訓練款通常選擇及膝以下(Jammers)或平腳款(Trunks),能提供適度的肌肉壓縮與保護,同時避免過度暴露引起孩子不適。比賽款則可選擇更貼身的剪裁以降低水阻。建議根據孩子的活動需求與個人偏好來選擇。
Q: How should I choose the material of children’s swimming trunks? What is the difference between PBT and nylon?
A: PBT(聚對苯二甲酸丁二醇酯)是最耐氯的材質,適合每天訓練的兒童使用,可承受高頻率泳池氯水侵蝕,壽命長達 1-2 年;尼龍 / 萊卡混紡則更柔軟舒適、色彩豐富,但耐氯性較弱,適合偶爾游泳或比賽使用。對於經常參加游泳課的孩子,強烈建議選擇 PBT 材質。
Q: How to judge whether the size of children's swimming trunks is appropriate?
A: 合適的兒童泳褲應該貼合但不緊繃:腰部不應有過深的壓痕,褲管不應過度往上捲曲。讓孩子做幾個踢腿動作測試,如果泳褲位置穩定不移位,即為合適尺寸。若孩子在兩個尺寸之間,建議選擇稍大一點的款式,因為成長速度快,也可多穿一段時間。
