Westside Discs VIP AIR Underworld Fairway Driver Golf Disc Review (2026)

What it is

The Underworld is a fairway driver from Westside Discs with published flight numbers of speed 7, glide 6, turn -3, and fade 1, placing it firmly in the understable end of the fairway driver category. This copy is molded in VIP AIR plastic, a lightweight version of Westside's transparent VIP blend produced with an air injection process that reduces the disc's overall weight. Westside markets the mold toward newer players who want an easy way to throw anhyzer lines, while also noting that more advanced throwers can use it for continuous anhyzer shots or as a roller off the tee.

Fit for the job

With a turn of -3 and only a fade of 1, the Underworld wants to bank one direction through most of its flight before settling gently at the end, which makes it a natural fit for players still building arm speed who need extra glide to reach real distance. It also suits players specifically looking for a disc that holds an anhyzer angle well, since that turn number is what lets the disc curve smoothly through a controlled banking line rather than fighting back to center. Stronger throwers can still get value from it as a utility disc for rollers or hyzer flip shots, but it is not built as a workhorse distance driver for high power arms.

Features and specs

Westside lists the Underworld's flight numbers as speed 7, glide 6, turn -3, and fade 1, and this listing is molded in VIP AIR plastic, sold across the 150 to 164 gram range in roughly 5 gram weight bands. The speed 7 rating puts it toward the lower end of fairway drivers, meaning even players without a fast arm can generate the speed needed to get the disc turning and gliding as designed. The glide rating of 6 is a meaningful part of the disc's appeal, since it is what keeps the disc airborne and carrying distance even after the turn has flattened the flight path.

Build and materials

VIP AIR is Westside's lightweight take on its VIP plastic line, which the company describes as a super durable, hi tech blend that is transparent enough to see through. The AIR process specifically reduces the disc's weight compared with a standard VIP pour, which is what allows this Underworld to be sold in the 150 to 164 gram range rather than the heavier weights typical of many fairway drivers. That lighter build is what gives beginners and lower power throwers more glide and easier distance, though it also means the disc offers less resistance to wind and course obstacles than a heavier plastic pour of the same mold.

Value for money

As an understable fairway driver built specifically to help newer players and lower arm speed throwers achieve smooth, controllable distance, the Underworld in VIP AIR plastic fills a clear role in a growing bag, and the VIP blend should hold up to regular play better than the softer base plastics some starter discs use. It is a strong value pick for players focused on learning anhyzer shots or simply looking for an easy source of extra distance while their arm speed develops. Stronger, more experienced players will likely get less long term use from it, since its light weight and pronounced understable turn are easier to overpower once technique and arm speed improve.
