FlexFoam frame technology

Light, stable and seawater-ready.

FlexFoam keeps the frame light, buoyant and stable around sweat, spray and seawater.

Shop FlexFoam sunglasses

01 Floats in seawater

A dropped pair has more margin around boats, beaches and paddle sessions.

02 Low-weight comfort

The frame stays easier to wear through heat, sweat and repeated outdoor use.

03 Stable fit control

Works with FlexLock temples to help reduce slipping and bouncing.

Common issue

Where ordinary sunglasses fail around water.

Wet hands, sweat and seawater expose the weak points quickly: sinking, pressure, slipping and hard-to-trust fit.

Sinks fast near the coast

A dropped pair near shore, paddle boards or boats can disappear immediately.

Feels heavier as the day goes on

A frame that feels fine at first can become distracting after hours outside.

Starts moving when sweat builds

Sweat, spray and movement can turn a weak fit into constant adjustment.

Hard to trust with wet hands

Wet launches and landings are not the moment to worry about grip or bounce.

Built for casual use, not real water days

A casual frame can look fine on shore but fail once the day gets wet.

Quick answer

What is FlexFoam?

FlexFoam is 2nu's lightweight floating frame system. It helps the frame stay buoyant in seawater, feel lighter on long days and work with FlexLock temples for a steadier fit.

How 2nu solves it

Made for water, movement and long wear.

FlexFoam focuses on the frame problems customers actually feel outside: buoyancy, lower weight, hand-adjustable fit and wet-use stability.

Floats in seawater when dropped

A dropped pair near shore, on a paddle or beside a boat is less likely to disappear immediately.

Low weight you stop noticing

Lower frame weight helps comfort hold through coast walks, paddle sessions and beach hours.

Stable fit when wet and moving

FlexLock temples help keep the frame settled through spray, sweat and repeated movement.

Easy to adjust by hand

Fine-tune the hold by hand without living with pressure points.

Built for paddling, sailing and beach use

Built for days that move between shore, deck, sand and water.

Lens options that fit how you use them

Pair FlexFoam with Hexachroma or TVO Pro based on glare and screen needs.

Choose by use case

Start with the frame need, then choose the lens.

FlexFoam is the frame foundation. Choose Hexachroma for screen-friendly clarity, or TVO Pro for focused glare control.

Water

Beach, boat and paddle use

Choose FlexFoam when seawater, spray and wet handling are part of the day.

Shop water-ready options

Light

Changing light and screen checks

Start with Hexachroma when phone, watch or dashboard readability matters alongside polarized glare control.

FAQ

Practical FlexFoam questions.

Is FlexFoam a lens technology?

No. FlexFoam is the frame material and fit platform. Lens behavior comes from the lens setup you choose, such as Hexachroma or TVO Pro.

Does every FlexFoam setup float the same way?

Buoyancy depends on the full configuration, especially lens weight. For maximum seawater buoyancy, choose configurations marked with FLOAT MAX and check the product details before buying.

Which 2nu models use FlexFoam?

Selected Fancy, Halo, Cogs, Ovo and Zealot configurations use FlexFoam. The frame shape still changes by model, so choose by coverage, fit feel and lens need.

Is Floatantium the same as FlexFoam?

Floatantium was the earlier naming for the same frame technology. The customer-facing name is now FlexFoam because it better explains the low-weight, flexible and seawater-ready frame behavior.

Should I choose Hexachroma or TVO Pro with FlexFoam?

Choose Hexachroma when screen-friendly polarized clarity and changing light are important. Choose TVO Pro when your main need is focused polarized glare control in bright outdoor conditions.

Ready to choose

Choose a FlexFoam frame, then match the lens to your light.

Selected Fancy, Halo, Cogs, Ovo and Zealot configurations use FlexFoam. Pick Hexachroma or TVO Pro based on light, glare and screen needs.

UV400 protection ensures that sunglasses effectively block 100% of harmful ultraviolet (UV) rays, including both UVA and UVB, up to wavelengths of 400 nanometers. This advanced level of protection helps safeguard the eyes from prolonged sun exposure, reducing the risk of conditions such as cataracts, macular degeneration, and other UV-related eye damage.

Hexachroma

面對熱帶高溫、海水鹽霧與防曬霜的挑戰，一般鏡片往往不得不妥協。但 2nu 選擇正面迎擊。
我們獨家研發的 Metonic™ 鍍膜 能在鏡片表面形成一道強效的疏水疏油保護盾。這意味著水珠遇上即瞬間滑落，指紋油污一抹即淨，更有效阻隔鹽分侵蝕，確保視野不受干擾。
💧 強效排斥： 隔絕潮濕水氣、劇烈運動後的汗水及皮膚油脂。
🛡️ 堅固抵禦： 對抗海水腐蝕及日常微細刮痕，延長鏡片壽命。
👁️ 極致視野： 無論是穿梭於濕熱的城市街道，還是征服崎嶇的海岸山徑，視野始終清晰鋭利。

浮力，源於細節。Hexachroma 系列採用了 超輕量鏡片技術 (Ultra-Lightweight Lenses)，從根源減輕重量，提供比一般浮水眼鏡更優越的浮力表現。
鏡片更輕： 在保持高清晰度與防撞保護的同時，大幅降低整體重量。
浮力升級： 經測試證實，在水溫 32°C 以下 的海水中依然能保持漂浮。
專業提示： 即使在密度較低的暖水海域（如熱帶衝浪點），Hexachroma 依然能為你提供最可靠的防沉保護。

我們的鏡框採用創新材質 FlexFoam™ 製成，具備輕盈、柔軟且極具彈性的特性，提供卓越的舒適度與貼合性。
雖然我們主要推薦給一般頭型的使用者，但 FlexFoam™ 的獨特可調性，讓它能自然貼合各種頭型尺寸。與傳統鏡框需依賴精確尺寸不同，FlexFoam™ 能靈活調整，即使您的頭型偏大或偏小，也能享有穩固舒適的配戴體驗。

Polarized lenses are specially designed to reduce glare and improve visual clarity, particularly in bright outdoor conditions. They contain a chemical filter that aligns light waves, allowing only vertically oriented light to pass through while blocking horizontally reflected glare from surfaces like water, roads, and snow.
Benefits of Polarized Lenses:
Reduced glare: Helps minimize reflections from flat surfaces, improving visibility.
Enhanced contrast: Makes objects appear sharper and clearer.
Less eye strain: Reduces discomfort caused by excessive brightness.
Better vision in bright environments: Ideal for outdoor activities like fishing, boating, and driving.

UV400 protection ensures that sunglasses effectively block 100% of harmful ultraviolet (UV) rays, including both UVA and UVB, up to wavelengths of 400 nanometers. This advanced level of protection helps safeguard the eyes from prolonged sun exposure, reducing the risk of conditions such as cataracts, macular degeneration, and other UV-related eye damage.

面對熱帶高溫、海水鹽霧與防曬霜的挑戰，一般鏡片往往不得不妥協。但 2nu 選擇正面迎擊。
我們獨家研發的 Metonic™ 鍍膜 能在鏡片表面形成一道強效的疏水疏油保護盾。這意味著水珠遇上即瞬間滑落，指紋油污一抹即淨，更有效阻隔鹽分侵蝕，確保視野不受干擾。
💧 強效排斥： 隔絕潮濕水氣、劇烈運動後的汗水及皮膚油脂。
🛡️ 堅固抵禦： 對抗海水腐蝕及日常微細刮痕，延長鏡片壽命。
👁️ 極致視野： 無論是穿梭於濕熱的城市街道，還是征服崎嶇的海岸山徑，視野始終清晰鋭利。

FlexFoam™ × FlexLock™
Engineered for movement. Built for extremes.
FlexFoam™ delivers weightless, all-day comfort that stays effortless once you’re moving. Inside, FlexLock™ features hand-adjustable temples, giving you a secure, personalised fit that holds when conditions get demanding.

Seawater Buoyancy Index (SBI)
We rated, not guessed.
SBI25 (Seawater Standard)
Engineered for reliable buoyancy in seawater conditions ≤ 25°C.
FLOAT MAX (Hexachroma™ Only)
Our highest buoyancy rating, available exclusively on Hexachroma™ grade sunglasses.
Built to float in all seawater conditions — cold, rough, or unpredictable.
When losing your sunglasses isn’t an option, this is the one.

Prescription (RX) Note

Corrective lenses add weight, which means RX sunglasses will not float. Physics wins.
For seawater sessions, pair RX models with a floating strap and stay focused on the adventure ahead.

Polarized lenses are specially designed to reduce glare and improve visual clarity, particularly in bright outdoor conditions. They contain a chemical filter that aligns light waves, allowing only vertically oriented light to pass through while blocking horizontally reflected glare from surfaces like water, roads, and snow.
Benefits of Polarized Lenses:
Reduced glare: Helps minimize reflections from flat surfaces, improving visibility.
Enhanced contrast: Makes objects appear sharper and clearer.
Less eye strain: Reduces discomfort caused by excessive brightness.
Better vision in bright environments: Ideal for outdoor activities like fishing, boating, and driving.

我們的鏡框採用創新材質 FlexFoam™ 製成，這是一種輕盈、超柔軟且極具彈性的複合材料，能提供卓越的舒適度與適應性。
雖然我們主要推薦給頭型偏大的使用者，但 FlexFoam™ 的獨特可調性，讓它能自然貼合各種頭型尺寸，確保穩固舒適的配戴體驗。與傳統鏡框需依賴精確尺寸不同，FlexFoam™ 能靈活調整，不論您的頭型屬於一般或偏大，都能輕鬆適配。
