Product Information
The Seac Set Bis Giglio Dry is a snorkeling combo that pairs the Seac Giglio single-lens mask with the Seac Fast Tech Dry snorkel, built for recreational snorkeling, light freediving, and casual mask-and-snorkel diving. The mask uses a polycarbonate frame with a single tempered glass lens and a hypoallergenic silicone skirt, while the snorkel adds a dry top system and a purge valve so water stays out of the tube and clears easily when it does get in.
Who it is for
This set suits snorkelers and freedivers who want a low-fuss, single-lens mask paired with a snorkel that manages splash and submersion on its own. The Giglio mask's anatomically shaped face piece and two-button buckle system make it quick to fit and adjust, and the set is offered in an adult size as well as a smaller-faced MD (junior) size, so it works for both grown-up swimmers and younger or smaller-faced snorkelers in the same family.
Key details
- Mask lens: single tempered glass lens in a polycarbonate frame
- Mask skirt and strap: hypoallergenic silicone
- Mask adjustment: two-button buckle system on both sides for quick resizing
- Snorkel mouthpiece: ergonomic silicone for a relaxed jaw
- Snorkel top: dry top system to block water entering the tube opening
- Snorkel base: purge valve to expel any water that does get in
- Snorkel attachment: clip that secures the snorkel to the mask strap
Compatibility and sizing
The set comes in two sizes: an adult version (Seac Giglio mask and Fast Tech Dry snorkel) and a smaller MD/junior version with a reduced mask and snorkel. Both sizes are offered in Blue/Clear and Black colorways. The Fast Tech Dry snorkel's clip is designed to attach to the Giglio mask strap, though the same clip style can also secure the snorkel to other masks with a compatible strap.

Frequently Asked Questions
What is the difference between the adult and junior Seac Giglio Dry set?
The adult set uses the standard Seac Giglio mask and Fast Tech Dry snorkel, while the junior version uses the MD (smaller-face) Giglio mask and a reduced-size snorkel. Both sizes share the same tempered glass lens, silicone skirt, dry top, and purge valve features, just scaled for a smaller face.
What does the dry top on the Fast Tech Dry snorkel do?
The dry top system on the Fast Tech Dry snorkel is designed to block water from entering the tube opening at the surface, so less water reaches your mouth while snorkeling. A purge valve at the base also lets you expel any water that does get in.
Can the Fast Tech Dry snorkel be used with a different mask?
Yes. The snorkel attaches with a clip that secures it to a mask strap, and while it is paired with the Seac Giglio mask in this set, the same clip style can generally attach to other masks with a compatible strap.
What colors is the Seac Set Bis Giglio Dry available in?
This set is offered in Blue/Clear and Black, each available in both the adult size and the smaller MD junior size, for a total of four color and size combinations.
