The Truth About Rain Coats They Don't Want You To Know

Summary

The video script challenges the effectiveness of Gortex as a waterproof and breathable material for rainwear. It discusses the science behind membrane-based coats, explaining how Gortex's breathability is compromised in high humidity, leading to condensation and discomfort. The script also addresses the durability of the DWR coating, which is essential for preventing wetting out but wears off over time. Environmental concerns related to the production and chemicals used in Gortex are highlighted, questioning its sustainability. The speaker suggests alternative raincoat materials that move liquid water away from the body, offering a different approach to staying dry.

Takeaways

• ❓ The speaker questions the effectiveness of Gortex, suggesting it might be one of the biggest marketing cons due to its performance not living up to the marketing hype.
• 💧 Gortex coats are criticized for causing condensation on the inside and potential delamination of layers, leading to discomfort and reduced effectiveness.
• 🌟 Despite issues, Gortex's popularity is increasing due to the rise of 'gorpcore' fashion, with many purchasing the coats for style over functionality.
• 🧥 The video aims to explore alternatives to Gortex, focusing on long-lasting and comfortable solutions for staying dry in the rain.
• 💭 Gortex is marketed as 'breathable and waterproof,' but the script explains that these claims are misleading as the coat cannot be both breathable and waterproof simultaneously.
• 🌡️ The script discusses the science behind vapor pressure gradients and how they affect the breathability of Gortex coats, especially in high humidity conditions.
• 💧 The issue of condensation forming on the inside of the coat is highlighted, which can block the pores of the Gortex membrane and render it non-breathable.
• 🌬️ The role of air movement in vapor transfer is mentioned, and how wearing a coat limits this natural process, contributing to the coat's ineffectiveness.
• 🔍 The script delves into the durability of the DWR (Durable Water Repellent) treatment on Gortex coats, noting that it wears off over time and can lead to wetting out.
• 🚫 The environmental impact of Gortex production and DWR treatments is called into question, with the mention of lawsuits and pollution concerns.
• 🌿 The speaker suggests an alternative to Gortex: Param raincoats, which use a different approach to keep the wearer dry by moving liquid water away from the body.

Q & A

Gore-Tex的工作原理是什么？

Gore-Tex的工作原理基于其独特的膜技术。这种膜由数以百万计的微小孔隙组成，孔隙尺寸是水滴的2万倍小，但比水蒸气分子大700倍。这种尺寸差异使得水蒸气可以通过膜逸出，同时阻止外部水分渗透。每个孔隙都被一种疏水材料包围，防止水分子进入，同时孔隙足够大，允许空气分子通过，确保透气性。这种防水和透气性的结合使得Gore-Tex成为户外运动爱好者和运动员的首选。

Gore-Tex的DWR技术是什么？

DWR代表持久性防水（Durable Water Repellent），是Gore-Tex技术的一部分。DWR是一种应用于Gore-Tex外层面料的涂层，使水珠能够在面料表面形成珠状并滚落，而不是渗透进面料。这种技术有助于提高服装的防水性能，但与Gore-Tex膜本身的防水透气性能不同。如果DWR效果减弱，Gore-Tex膜的性能也会受到影响。

Gore-Tex产品在极端条件下的表现如何？

Gore-Tex的技术在地球上一些最极端的条件下经过了测试和验证。例如，在登山运动中，Gore-Tex是登山者在高海拔山峰和极端天气条件下的可靠伴侣。它的防水性和透气性为登山者提供了必要的保护，以抵御雪、冰和极端寒冷。

Gore-Tex产品如何维护和清洁？

为了保持Gore-Tex服装的透气性和耐用性，建议遵循制造商的清洁说明进行清洗。清洗可以去除堵塞纤维的污垢、汗水和油脂。此外，随着使用，外层面料上的DWR涂层可能会磨损，需要重新涂抹DWR喷雾或进行水洗处理以恢复其防水性。避免使用漂白剂、织物柔软剂和强烈的洗涤剂，因为这些物质可能导致Gore-Tex膜和表面面料分层。

Gore-Tex产品在潮湿天气中的表现如何？

Gore-Tex产品在潮湿天气中提供始终如一的出色性能。耐用的外层面料提供了持久的防水和透气性，即使在长时间的大雨或暴雪中也能保持干爽舒适。汗气可以轻松排出，让您保持干爽和舒适。

Gore-Tex产品是否环保？

Gore-Tex公司正在努力减少其环境影响，通过使用回收材料、减少废物和寻求更可持续的制造过程。他们正在尝试转向一种不含全氟化合物（PFCs）的材料，称为ePE，以减少其环境足迹，同时保持高性能。Gore-Tex的目标是让户外爱好者在享受自然的同时，尽量减少他们的碳足迹。

Gore-Tex产品有哪些不同的类型？

Gore-Tex产品有多种不同的类型，包括基本的Gore-Tex、Gore-Tex Active、Gore-Tex Pro、Gore-Tex SURROUND等。每种类型都有其特定的设计和用途，以满足不同的户外活动需求。例如，Gore-Tex Active系列专为活动量较大的户外活动设计，提供更好的透气性和灵活性。

Gore-Tex产品如何保证其防水性能？

Gore-Tex产品的防水性能是通过其独特的膜技术和DWR涂层来保证的。膜技术利用微孔结构来阻止水分子进入，同时允许水蒸气分子逸出。DWR涂层则使水珠在面料表面形成珠状并滚落，减少水分渗透。此外，Gore-Tex还提供了临时修复补丁，以在户外活动中快速修复小洞和撕裂，防止问题恶化。

Gore-Tex产品在户外运动中的实际表现如何？

Gore-Tex产品在户外运动中的实际表现因其设计和使用条件而异。一些用户报告称，在持续的雨中，即使是高端的Gore-Tex产品也可能会发生湿透现象。然而，通过适当的维护，如定期清洗和重新涂抹DWR涂层，可以最大限度地减少这种情况的发生，并保持其防水和透气性能。

Gore-Tex产品是否适合日常穿着？

Gore-Tex产品不仅适合户外运动，也越来越受到日常穿着者的青睐。随着gorpcore风格的兴起，越来越多的人选择Gore-Tex产品作为时尚和日常穿着的选择。Gore-Tex的透气性和防水性使其成为应对各种天气条件的理想选择。
