Danielle Quah –
What are the limitations of the water-repellent material used in the Leptonix Castor ADV / BCD Jacket? Would it be effective in heavy rainfall or snow?
Imran Hanafiah –
Thank you, Danielle, for reaching out to us about the water-repellent material in our Leptonix Castor ADV / BCD Jacket. While our fabric is treated with a water-repellent coating to help protect against rain and snow, it is not completely waterproof. In heavy rainfall or snow, the fabric may not be able to keep up with the intense water pressure, which could result in some water seeping through. However, this should not affect the overall performance of the jacket. The material is designed to be breathable and moisture-wicking, so you can stay comfortable and dry even in wet conditions. Additionally, the jacket features a 2-layer design with a sealed seam construction to improve water resistance. If you have any further questions, please don’t hesitate to contact us.
