SUBLUE 180° Panoramic Tempered Glass Dive Mask & Snorkel Set — A Real Diver's Review for Open Water
I'll be honest with you — I've gone through more snorkel sets than I care to admit. Cheap ones that fog up five minutes in, "panoramic" masks that barely widen your view past a slit, snorkels with valves that jam the second sand gets near them. So when I strapped on the SUBLUE 180° Panoramic Tempered Glass Dive Mask and Snorkel Set for a few open water sessions, I wasn't expecting much. I was wrong, and this review walks through exactly why.
Quick Verdict
If you want a dive mask and snorkel set for open water that actually delivers a wide field of view, doesn't leak, and doesn't fog after ten minutes, the SUBLUE 180° set earns its spot in your dive bag. It's not a $200 pro rig, but for the price, it punches well above its weight for snorkeling, freediving warm-ups, and casual scuba surface swims.
Why the "180° Panoramic" Claim Actually Holds Up
Most masks marketed as "panoramic" are really just wide single-lens designs that trick you with marketing copy. The SUBLUE version uses a curved tempered glass lens that genuinely extends peripheral vision instead of just widening the front window. The first time I put it on in open water, I noticed I could catch movement to my sides without turning my whole head — which matters more than people think when you're watching for boat traffic, other swimmers, or just trying not to miss a sea turtle drifting past on your left.
Tempered glass is the detail that sold me. Regular plastic or acrylic lenses scratch fast and can warp slightly under pressure changes. Tempered glass resists both, and it's the same reason it's the standard in higher-end dive gear rather than budget snorkel sets.
Seal, Comfort, and Fit
A panoramic view means nothing if the mask leaks. SUBLUE uses a soft silicone skirt that hugs the face without the usual pressure points around the nose bridge and temples — the two spots where cheaper masks always dig in after 20 minutes. I tested it with a beard (short, not full lumberjack) and got a workable seal, though anyone with heavier facial hair should expect the occasional trickle, same as with any mask.
The strap uses a quick-adjust buckle system rather than the old plastic clip-and-slide, so getting a snug fit takes seconds instead of fiddly minutes standing waist-deep in water while your group waits.
The Snorkel: Dry-Top Valve That Actually Works
The included snorkel uses a splash guard and purge valve setup, meaning if a wave hits the top, it deflects water instead of funneling it straight down the tube. There's also a bottom purge valve so if water does get in, one exhale clears it instead of you having to surface and dump the whole tube. For open water use — where you don't have the flat, predictable conditions of a pool — this is the feature that separates a usable snorkel from a frustrating one.
What's Included in the Set
- SUBLUE 180° Panoramic tempered glass dive mask
- Dry-top snorkel with purge valve
- Quick-adjust silicone strap
- Snorkel mount clip
- Protective carry case
Anti-Fog Performance in Real Conditions
Anti-fog coating claims are cheap to print on a box and rarely hold up after the third dive. I ran mine through repeated dunks over two separate sessions, and fogging stayed minimal as long as I did the basic pre-dive rinse (a drop of baby shampoo or dedicated defog solution, swished and rinsed). It's not magic — no mask is — but it noticeably outperformed the last two snorkel sets I'd used before this one.
Who This Set Is Actually For
| Use Case | How It Performs |
|---|---|
| Recreational snorkeling | Excellent — this is its home turf |
| Open water swimming | Very good, wide field of view helps with sighting |
| Freediving practice | Good for shallow, casual sessions |
| Scuba surface intervals | Works well as a lightweight backup mask |
| Technical/deep scuba diving | Not designed for this — stick to a certified dive mask rated for depth |
What I Liked
- Genuinely wide peripheral view, not just marketing language
- Tempered glass feels sturdier and scratch-resistant compared to plastic lenses
- Dry-top snorkel valve handled chop and small waves well
- Fast strap adjustment, comfortable for longer sessions
- Comes with a protective case for travel
Where It Falls Short
- Heavier facial hair can compromise the seal, same as most masks
- Not rated for deep scuba diving — it's an open water / snorkel product
- Anti-fog coating still needs the standard pre-rinse routine to perform best

What Other Divers Are Saying
Snorkel and dive mask sets get debated a lot in diving communities, mostly around whether a snorkel kit is even worth carrying alongside full scuba gear. There's a solid discussion thread on r/scuba covering exactly that question, worth a read if you're deciding whether a set like this fits your kit: Is it worth getting a snorkel kit for your scuba gear?

SUBLUE's Trustpilot Reputation

Final Verdict
The SUBLUE 180° Panoramic Tempered Glass Dive Mask and Snorkel Set does what it promises: a wider, clearer field of view, a snorkel valve that actually handles open water conditions, and build quality that feels a step above the usual budget sets. It's not built for deep technical diving, and no mask fully solves the beard-seal problem — but for open water snorkeling, freediving warm-ups, and casual scuba surface use, it's one of the more complete sets I've tested at this price point.
