If you want heavy-duty lashing straps to secure cargo like surfboards, kayaks, or luggage to your SUV roof, choose Bison Gear Tie Down Straps; if you need to silence a whistling noise from your existing Thule WingBar Evo system by replacing a missing cover strip, choose splash n color SplashNColor Roof Bar. These two items serve completely different functions on the road, and picking the wrong one leaves you with either an insecure load or a noisy drive.
• Best for SUV owners who actively transport large gear.
• splash n color SplashNColor Roof Bar: The main benefit is stopping annoying wind whistle from exposed slots, but it is a small plastic part that does not add any carrying capacity. Best for drivers whose racks are already installed but have a specific noise issue.
• The Verdict: You need Bison Gear if you are building a load-hauling setup, but you need splash n color only if you are fixing a noise problem on a bar you already own.
This product is designed for the active SUV owner who treats their vehicle as a mobile hauling platform. The core of this package is the industrial-grade polyester webbing, which comes in a substantial 1-inch width. That thickness matters because thin straps tend to cut into soft cargo or slip under tension, whereas these wider fibers distribute pressure evenly.
The design focuses on reliability and organization. Each unit features a rustproof metal alloy cam buckle, which provides a secure locking mechanism that won't corrode even after repeated exposure to saltwater or rain. The set includes four straps, each measuring 16 feet in length. This generous length allows for complex lashing patterns across wide loads, ensuring you can wrap around bulky items like kayaks or lumber multiple times before securing the end. The inclusion of a durable organizer bag means you aren't left with a tangled mess of black nylon in your trunk; instead, you have a ready-to-go kit stashed neatly under a seat.
Who should buy this? If you regularly take your SUV to the beach, the lake, or the lumber yard, this is the essential gear you need. It is for the driver who understands that safety comes from redundancy and strong materials. However, skip this product if you simply want to mount a bike rack or carry a single lightweight item where standard factory hooks might suffice. You also do not need this if you are looking for a structural component of your rack itself, as these are supplementary tie-downs that rely on your existing crossbars.

This item is not a tool for hauling; it is a precision fix for a specific acoustic annoyance. The splash n color SplashNColor Roof Bar is a slot cover designed specifically for Thule WingBar Evo systems. Its sole purpose is to close the exposed openings on the underside of the roof rack bars. When air rushes over these open slots at highway speeds, it creates a high-pitched whistle that can be distracting and fatiguing during long drives. This plastic piece slides into place to block those openings, effectively silencing the noise at its source.
It is sold as a single unit (one size) rather than a multi-pack, reflecting its role as a replacement part rather than a bulk accessory. The manufacturer explicitly notes that it is compatible with the specific geometry of the Thule WingBar Evo, meaning it fits the lower slots where carrier feet sit. It allows you to keep using your current roof rack even if the original lower cover strip has been lost, broken, or removed. It does not include any mounting hardware, so it assumes you are sliding it into an existing channel or attaching it to your bar's structure.
Who needs this? This is strictly for the SUV owner who already has a functioning roof rack system but is plagued by wind noise. It is perfect for commuters or road trippers who spend hours on the highway and find the whistle unbearable. If your rack is missing this specific plastic strip, buying a whole new bar is unnecessary expense; this part restores the aerodynamic seal. Conversely, if you do not have a Thule WingBar Evo, or if your rack does not have exposed slots underneath causing noise, this item will do nothing for you. It adds no holding power and cannot be used to secure any cargo.
• Best for eliminating wind noise → splash n color SplashNColor Roof Bar, designed specifically to block airflow through exposed rack slots.
• Best for durability under harsh conditions → Bison Gear Tie Down Straps, featuring industrial-grade polyester and a lifetime warranty against failure.
• Best for restoring a damaged rack → splash n color SplashNColor Roof Bar, acting as a direct replacement for a missing lower cover strip.
• Best for versatility → Bison Gear Tie Down Straps, as 16-foot lengths allow for various lashing angles and load sizes.
• Best for quiet highway driving → splash n color SplashNColor Roof Bar, turning a loud distraction into a silent ride.
• Best value for frequent travelers → Bison Gear Tie Down Straps, offering a 4-pack that handles multiple trips and varied loads.
• Best for specific compatibility → splash n color SplashNColor Roof Bar, provided you own the exact Thule WingBar Evo model it matches.
I recommend the Bison Gear Tie Down Straps for most SUV owners because securing your gear safely is a higher priority than silencing a minor noise. While the splash n color product solves a real annoyance, it is a niche fix for a very specific brand of rack. The Bison Gear straps offer tangible utility: they let you haul kayaks, bikes, and cargo with confidence, backed by a lifetime warranty and heavy-duty construction. Unless you are driving a Thule WingBar Evo and hate the sound of the wind, the straps provide far more value for the money. I would buy the Bison Gear set to ensure my cargo stays put, and I would only look at the splash n color option if I were already fighting a persistent whistle on my specific rack.
