地球上約有一半的人口會經歷月經，根據統計，女性一生中約需使用1萬片衛生棉，而傳統衛生棉材質中90%為塑膠，每片需要500年才能自然分解。不僅對環境造成巨大壓力，也間接帶來碳排放問題：每片衛生棉的生產與運輸平均會產生5克CO₂排放，全球每年因此產生數十萬噸碳排放，對淨零目標構成挑戰。
衛生棉因方便性、使用習慣及心理接受度，仍是大多數人的首選。除了環保議題外，衛生棉還涉及多方面考量，因此，我們希望在不改變使用習慣的前提下，為一次性衛生棉提供更環保、符合需求的創新選擇，降低女性生理期開銷，同時推動更完善的月經改革，讓生理期變得更輕鬆、貼心與便利。
Onefit pad 是一款多尺寸合一的衛生棉，透過經血熱點分析，我們將 23CM 衛生棉重新設計與組合，使其能以最少的原料發揮最大效益。其中間層可向後自由抽拉，最長可延伸至 32CM，使一片 23CM 衛生棉即可滿足日夜使用需求，同時減少資源浪費。
這項設計不僅提升便利性、減少個人衛生用品開支，降低月經貧窮的影響，還能減少不同尺寸衛生棉的生產成本與資源浪費，進而促進環保永續與負責任的生產模式。

OneFit Pad

Approximately half of the world’s population experiences menstruation. Statistics show that a woman will use around 10,000 sanitary pads in her lifetime. However, traditional pads are composed of 90% plastic, taking up to 500 years to decompose naturally. This not only places a significant burden on the environment but also contributes to carbon emissions. The production and transportation of a single sanitary pad generate an average of 5 grams of CO₂ emissions, leading to hundreds of thousands of tons of carbon emissions globally each year—posing a challenge to a

Despite environmental concerns, sanitary pads remain the preferred choice for most people due to their convenience, user habits, and psychological acceptance. Beyond sustainability, menstrual products involve multiple considerations. Therefore, we aim to provide a more eco-friendly and practical alternative to disposable pads without requiring users to change their habits. Our goal is to reduce the cost of menstrual care while promoting menstrual reform, making periods more comfortable, thoughtful, and convenient.

Onefit Pad is an all-in-one, multi-size sanitary pad designed to maximize efficiency with minimal materials. Through an analysis of menstrual flow patterns, we have redesigned and restructured a 23cm pad to optimize its use. The middle layer can be freely extended backward, reaching up to 32cm in length, allowing a single 23cm pad to meet both day and night needs while minimizing resource waste.

This innovative design not only enhances convenience and reduces the cost of personal hygiene products but also helps mitigate the impact of period poverty. Additionally, it lowers production costs and resource consumption associated with manufacturing pads of different sizes, contributing to environmental sustainability and responsible production practices.
