Fourth Element 900ml Gulper in Sea Moss
Every great dive trip requires proper hydration. The Fourth Element 900ml Gulper in the striking Sea Moss finish is far more than a standard water bottle. It serves as your trusted companion for long days on the dive boat, relaxing on the beach, or exploring rugged coastlines. Built with pro-grade stainless steel and advanced double-wall vacuum insulation, this robust canteen keeps your iced drinks completely chilled for up to 24 hours. If you prefer a warming coffee after a chilly local wreck dive, it keeps hot beverages perfectly warm for up to 12 hours.
We know you care deeply about the marine environments you explore. Choosing to refill this durable bottle helps actively reduce the single-use plastic waste that threatens our oceans and landfills. You make a genuinely eco-conscious choice every time you hydrate, protecting the underwater world for future adventures.
The clever, versatile lid features a secure twist-and-sip valve, allowing you to drink easily while on the move. When it is time to top up or wash out the bottle, the wide aperture makes the process quick, simple, and entirely spill-free. Grab the comfortable ergonomic handle, secure it in your dive bag, and head out to the water with complete confidence.
Features:
- Pro-Grade Stainless Steel: Exceptionally durable construction built to handle the rigours of an active, outdoor lifestyle.
- Double Wall Vacuum Insulation: Maintains internal temperatures, keeping drinks hot for up to 12 hours and cold for up to 24 hours.
- Sport Twist and Sip Valve: A smart closure system that allows for quick, easy drinking without removing the entire lid.
- Leak-Proof Design: Dependable seals ensure your dive bag and dry clothes stay completely safe from spills.
- BPA-Free Lid: Safe, non-toxic materials give you total peace of mind with every sip.
- Ergonomic Handle: Designed for a comfortable grip, making it easy to carry down to the dive site.
- Laser Etched Logo: A premium finish that resists fading and wear over time.
Why you will love it:
- All-day temperature control: Enjoy ice-cold refreshment or warming drinks exactly when you need them, regardless of the weather outside.
- Eco-conscious choice: Protect the oceans you love by eliminating your reliance on disposable plastic bottles.
- Drink on the go: The intuitive sports twist-and-sip valve provides effortless hydration between dives.
- Hassle-free maintenance: A wide neck opening makes cleaning and refilling incredibly straightforward.
