• intros：{"brand_intro":"迪卡侬（Decathlon）是法国体育用品零售巨头，成立于1976年，旗下拥有ITIWIT（水上运动）等多个自有品牌。ITIWIT专注于桨板、皮划艇、帆船等装备，以\"高性价比+创新设计\"著称。迪卡侬的品控体系采用\"实验室测试+实地用户测试\"双轨制，所有产品需通过200小时老化测试。其充气式救生圈包是2022年推出的爆款，利用充气浮力替代传统泡沫板，大幅降低重量和收纳体积。品牌理念是\"让运动触手可及\"，价格仅为专业品牌的1/3。","product_intro":"这款20L充气式救生圈包是迪卡侬针对入门级水上运动爱好者设计的轻量化浮力包。核心卖点是\"充气式浮力系统\"，未充气时仅重0.4kg，可折叠成巴掌大小；充气后浮力达35N，能支撑手机、钥匙等小件漂浮。包体采用PVC夹网布，拉链为普通防水拉链（非全防水）。相比泡沫浮力包，它更便携、更便宜，但浮力较小且需要手动充气（附赠迷你气泵）。竞品对比：适合偶尔玩桨板或帆船的新手，不适合专业救援。","key_specs":{"容量":"20L（可装防晒霜、水杯、零食）","浮力":"35N（充气后，约3.5kg承重）","材质":"PVC夹网布（0.8mm厚）","防水等级":"IPX5（防泼溅，不可浸没）","重量":"0.4kg（未充气）","适用人群":"桨板新手、帆船体验者、海滩休闲游客"}}
