• intros：{"brand_intro":"Sea to Summit（海到巅峰）1990年由Tim和Andrew两位户外爱好者创立于澳大利亚，以\"轻量化与防水\"为核心技术。品牌最初专注于防水袋和露营装备，后拓展至背包、睡袋等领域。其Dry Pack系列采用专利的TPU层压面料和卷口式防水设计，防水等级达到IPX8（可短时浸泡）。Sea to Summit坚持\"极致轻量\"理念，所有产品均通过欧洲环保标准（Bluesign认证），并提供5年质保。品牌在防水背包领域市场占有率全球第一，被誉为\"防水背包之王\"。","product_intro":"Dry Pack 45L是Sea to Summit的经典防水背包，45L容量适合1-3天溯溪、漂流或雨林徒步。核心卖点：全防水TPU面料（可漂浮）、卷口式密封设计、无缝焊接工艺、可拆卸胸带。相比Osprey的防雨罩方案，Dry Pack是真正的全防水背包，无需额外防雨罩；相比Mystery Ranch，其自重极轻（0.6kg），但无背负系统。适用场景：溯溪、漂流、雨林徒步、皮划艇。用户评价其\"防水性能无敌，掉进河里都不怕\"，但背负舒适度一般。","key_specs":{"容量":"45L（另有25L/65L可选）","重量":"0.6kg","背负系统":"无硬质背负，仅可调节胸带","防水设计":"TPU层压面料 + 卷口式密封，IPX8级防水","适配人群":"身高160-185cm，负重5-10kg的水上运动爱好者","材质":"TPU层压尼龙面料（可漂浮）"}}
