Protect your investment and stay concealed in the field. The LensCoatA(R) for the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary telephoto lens helps protect your valuable equipment from scrapes, bumps, and harsh outdoor conditions while preserving its appearance and resale value. By breaking up the recognizable shape of your lens, it also helps make your equipment less noticeable to wildlife. Constructed from premium neoprene, the LensCoatA(R) provides dependable protection while acting as a thermal barrier, making your lens more comfortable to handle in both hot and cold temperatures. The cover features clear plastic windows over the Auto Focus and Optical Stabilization controls, as well as the distance scale, allowing easy visibility and access to essential controls. The cover also includes an optional extension piece for when the lens is zoomed out to 600mm. This additional piece attaches quickly and easily with a Velcro closure, allowing you to add or remove it as needed without taking off the entire cover. Choose Your Variation: 1. Classic Version (Slip-On Style) Design: Traditional fixed custom glove-like fit that provides seamless protection around the lens. Installation: Stretches securely over the lens barrel for a precise, snug fit that stays comfortably in place during use while still allowing removal when needed. 2. V2 Version (Velcro Quick-Wrap Style) Design: Upgraded heavy-duty Velcro closure system for easy on/off access. Flexibility: Quickly remove or reinstall the cover whenever you need to clean or dry it, make adjustments, or change your camo for different shooting habitats and seasons. Convenience: Instantly swap styles and make changes without the stretching and pulling required by a slip-on cover. 3. Ultimate Combo Pack (Includes Both!) What you get: Both the Classic and V2 covers included together. Why choose it: Get the best of both options. Use the fixed custom glove-like Classic cover for a clean, secure fit, or switch to the V2 when you want easy on/off access, quick camo changes, or the ability to remove the cover for drying and cleaning.
