Exceptionally durable, lightweight and breathable Sidewinder SV Jacket has been a rugged and lean icon in the Arcteryx line for a decade. This top of the line Gore Tex ski shell is in excellent condition. Size is Large. I used it several times but no longer use it as much. The MSRP is over $800 so my asking price of $399 is firm (non negotiable). Feel free to reach out with any questions.
