Mares X-Vision Ultra LS Mask Review

The Mares X-Vision Ultra LS hits a sweet spot that many recreational divers are looking for – premium features at a mid-range price. I see this mask constantly in dive centers across Asia, and there’s a good reason for that. It offers the same LiquidSkin technology as the more expensive Force-X LS but in a slightly different package. The 20% wider field of vision compared to the previous X-Vision model makes a noticeable difference underwater, and the bi-silicone construction delivers excellent comfort. At around $125-$140, it’s positioned as a step up from basic masks but significantly cheaper than premium options like the Force-X LS or TUSA Paragon.

Key Specifications

The X-Vision Ultra LS features a dual-lens design with ultra-clear tempered glass. The frame is made from polycarbonate for durability while keeping weight down. The skirt uses Mares’ patented bi-silicone LiquidSkin technology – 45% softer and 270% more elastic than standard silicone according to Mares. This creates better facial adaptation and comfort. The X-shaped bi-silicone strap distributes pressure evenly. Weight is approximately 180 grams. The integrated buckle system makes strap adjustments easy even with gloves. Small horizontal ribs around the nose area relieve pressure – what Mares calls Tri-Comfort technology. The mask is compatible with prescription lenses ranging from -1.0 to -7.0 diopters and +1.5 to +3.0 diopters. Price typically ranges from $125-$140 USD. Available in multiple colors including clear, black, yellow, blue, and mirrored versions with gold or silver lenses. It’s designed for recreational divers, freedivers, and snorkelers who want reliable performance without premium pricing.

Real-World Performance

This mask shows up constantly with students and recreational divers, and the feedback is consistently positive. The LiquidSkin skirt really works as advertised. Multiple customers have mentioned that it feels noticeably softer against the face compared to their previous masks. One student who’s fairly new to diving mentioned she could wear it for three dives without any discomfort or pressure marks – something she hadn’t experienced with rental masks.

The seal quality is excellent. The bi-silicone construction adapts well to different face shapes, and I rarely hear complaints about leaking. The low internal volume makes it easy to clear, and equalization during descent is straightforward. The small ribs around the nose do seem to help with comfort – several divers have specifically mentioned that the mask doesn’t create pressure points around the nose bridge even on longer dives.

Field of vision is genuinely impressive for a dual-lens mask. The 20% increase over the previous X-Vision model is noticeable. You get good peripheral vision, though single-lens designs will always have a slight edge. For photography and videography work, many divers find the view more than adequate. The ultra-clear tempered glass provides sharp, distortion-free vision.

The X-shaped strap is well-designed. It distributes pressure across a wider area of your head compared to traditional straps, and the softer bi-silicone section at the back of the neck prevents hair pulling. The integrated buckles work smoothly and hold adjustments securely.

Durability has been solid based on what I’ve seen. The polycarbonate frame is lighter than masks with metal reinforcement, but it holds up well. A divemaster colleague in Thailand has been using his for over a year of daily diving – probably 300+ dives – and it still looks good. The LiquidSkin hasn’t degraded or become sticky.

The mirrored lens versions (gold and silver) are available for those who want them. According to Mares, the gold mirror increases visibility in murky water while the silver reduces reflection in shallow water or over sandy bottoms. I’ve heard mixed feedback – some divers love the look and claim improved visibility, others find the standard clear lenses just as good. The mirrored versions do cost a bit more.

Prescription lens installation is straightforward with the two-button buckle system. Mares offers a good range of corrective lenses, though they’re sold separately for around $60-$70 per pair.

Comparison Context

At $125-$140, the X-Vision Ultra LS competes directly with masks like the Scubapro Synergy Twin ($130), Cressi Big Eyes Evolution ($70), and sits below the Force-X LS ($185-$210). The main advantage over the Scubapro Synergy is the LiquidSkin technology – the X-Vision Ultra LS feels noticeably softer and more adaptive. The Cressi Big Eyes offers similar field of vision at a lower price, but the build quality and comfort don’t match the Mares.

Compared to its more expensive sibling, the Force-X LS, you’re sacrificing the steel-reinforced frame and slightly refined ergonomics. For most recreational divers, the X-Vision Ultra LS offers about 90% of the performance at roughly 65% of the price. Unless you specifically need the extra durability of the Force-X LS or dive very frequently, the X-Vision Ultra LS is probably the better value.

The Atomic Venom Frameless ($180) offers a wider field of view with its frameless design, but many divers prefer the X-Vision Ultra LS for its more secure frame and lower price point.

Our Professional Opinion

The X-Vision Ultra LS excels at delivering premium features at a reasonable price. The LiquidSkin bi-silicone technology provides excellent comfort that rivals masks costing $50-$70 more. The 20% wider field of vision is a genuine improvement over the standard X-Vision, and the Tri-Comfort nose ribs effectively reduce pressure points. Build quality is solid with the polycarbonate frame and ultra-clear tempered glass lenses.

The main limitation is that it’s not quite as durable as masks with metal-reinforced frames like the Force-X LS. The polycarbonate frame is perfectly adequate for recreational diving but might not hold up as well to the heavy use that professional divemasters and instructors put their gear through. The mirrored lens versions cost extra and their benefits are somewhat subjective – you’re mainly paying for aesthetics.

Final Recommendation

Buy the X-Vision Ultra LS if you want premium comfort and a wide field of view without paying premium prices. It’s an excellent choice for recreational divers who dive regularly – maybe 20-50 times per year – and want quality gear that will last. The LiquidSkin technology makes a real difference in comfort, especially on multi-dive days or longer dives.

It’s also ideal for divers who need prescription lenses. The two-button system makes lens changes easy, and Mares offers a comprehensive range of diopters. Freedivers and snorkelers appreciate the low volume and excellent seal.

Skip this mask if you’re a professional divemaster or instructor who needs maximum durability – the Force-X LS’s steel-reinforced frame would be a better investment for heavy daily use. Also skip it if you’re a casual vacation diver who only gets in the water once or twice a year – a basic $50-$70 mask like the Cressi Big Eyes would serve you just fine. If you want the absolute widest field of view and don’t mind paying more, frameless masks offer better peripheral vision.
