Glass Water Bottle – Silicone Sleeve 'Grip' programmed glass Glass & Vibe • water revitalisation • made in EU • 0.5 l

Glass Water Bottle – Silicone Sleeve 'Grip' (0.5 l) is not an ordinary glass bottle. The key difference lies in the material: FLASKA uses patented 'programmed' glass with Glass & Vibe technology, which according to the manufacturer is designed to 'revitalise' and 'structure' water within minutes (they recommend waiting 5 minutes and giving the water a quick shake before drinking).

In practice, people most often describe a smoother, more balanced taste even with tap water – and this is precisely why FLASKA is priced differently from standard glass bottles. The Silicone Sleeve 'Grip' ensures a more secure grip (practical for sports or sweaty hands); the narrower neck is comfortable for drinking and the wooden cap provides reliable sealing.

Glass Water Bottle – Silicone Sleeve “Grip” – Flaska

Glass water bottle with silicone sleeve “Grip” (0.5 l) differs from regular glass bottles mainly in the material used. Flaska uses patented “programmed” glass and Glass & Vibe technology, which, according to the manufacturer, is meant to “revitalise” and “structure” the water in a few minutes (they recommend waiting approximately 5 minutes and briefly shaking the water).

This type of glass and the manufacturer’s claimed impact on water justify the higher price compared to ordinary glass bottles. In practice, people often mention a smoother and more balanced taste even with tap water.

The glass is chemically stable, does not absorb odours or flavours, and is naturally BPA-free. BPA (bisphenol A) is a synthetic substance used in some plastics; it can migrate into drinks and is regulated in the EU, so a glass bottle is a simple way to reduce contact with plastics over the long term.

The bottle has a silicone sleeve “Grip” for a more secure hold (practical even during sports or with sweaty hands). The sleeve is removable and easy to clean, available in two colour variants: turquoise and purple; the wooden cap ensures reliable sealing and the bottle is not dishwasher safe.

How Do Flaska Bottles Differ from “Ordinary” Bottles?

Compared to plastic bottles, Flaska offers the benefits of glass: it is chemically stable, so it does not absorb odours or flavours and does not take on colours from drinks.

Glass is also naturally BPA-free and free of plasticisers, while plastic can over time absorb odours or release components into the drink.

In terms of hygiene, glass is easy to clean and withstands hot water and thorough mechanical cleaning with a brush without forming a film on the surface. In contrast, plastic is more easily scratched and micro-cracks can reduce washability and cleanliness.

In its lifecycle, a glass bottle has a long lifespan with careful use and is fully recyclable, reducing the need for single-use packaging. Although plastic is lighter, it usually has a shorter useful life and struggles to maintain flavour neutrality over time.

In practice, glass is heavier and more fragile, but Flaska balances this with accessories. Available are cork or neoprene sleeves and bottles in various sizes, so you can easily choose a version for work, sports, travel, and home serving.

Who Are Flaska Bottles For and Where Can You Use Them?

Flaska bottles are suitable for everyday hydration at home, in the office, at school, and in meetings. They are great for sports and leisure – for fitness, yoga, hiking, and cycling. Flaska also offers bottles for kids, helping to maintain regular hydration at school and activities.

 

Practical for travel and daily commuting – for backpacks or cars, on trips or in the city. The bottle can be easily refilled at fountains

or at home before leaving, so you have water always at hand.

 

Flaska bottles are available in various designs with an integrated sleeve, allowing you to choose a style that matches your taste and preferences. Options include cork, neoprene, and silicone covers, in a range of colours and with motifs for kids and adults.

 

The sleeve improves grip and enhances the appearance of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can be easily removed and cleaned with a damp cloth.

Why Choose Flaska

Flaska bottles are reusable glass bottles that keep water taste-neutral and free from unwanted odours. Glass is inert and naturally BPA-free, so it doesn't react with the drink or release anything into it.

Part of the brand's identity is an approach the manufacturer calls "programmed glass" – their own way of focusing on quality and water perception.

Flaska bottles easily integrate into everyday hydration at work, home, during study, and on the go. With a convenient neck and quality cap, they are easy to clean and drink from.

The brand offers several bottle sizes and various design options with cork, neoprene, or silicone sleeves. The sleeves facilitate grip and enhance the appearance of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can be easily removed and cleaned.

For long-lasting use, hand washing with a mild detergent and regular airing of the cap is recommended. Repeated use of a glass bottle helps reduce the amount of single-use plastic packaging.

Material and Processing

Glass water bottle – silicone cover "Grip" is made from European glass (known as programmed glass – Glass & Vibe), which is chemically stable and naturally free from bisphenol A and plasticisers. Glass doesn't absorb odours or flavours and is suitable for everyday use – for school, work, and leisure.

 

Protective cover consists of a silicone sleeve "Grip", which facilitates grip and enhances the appearance of the bottle; it is removable and can be cleaned with a damp cloth. The cap is screw-on and leak-proof with reliable sealing to prevent fluid leakage during carrying. All parts intended for contact with water meet standard food contact requirements.

 

Each piece undergoes careful assembly and inspection. To maintain appearance and function, we recommend hand washing and avoiding the dishwasher, microwave, and sudden temperature shocks.

Usage and Maintenance

  • Before first use, rinse the bottle and cap with warm water and a mild detergent.
  • Fill the bottle with tap water; for reliable sealing, fit and tightly screw on the cap.
  • Wash exclusively by hand using a soft brush and a mild detergent.
  • Do not use the dishwasher; avoid the microwave and sudden temperature shocks (do not pour boiling water, do not freeze).
  • Silicone cover "Grip" should be left to air dry after washing or soaking; do not dry on a direct heat source.

What to Buy with This Bottle?

FAQ

What is Glass & Vibe technology and how to use the bottle correctly?

The manufacturer states that a vibrational program is imprinted into the glass, which is meant to "tune" the water in about 5 minutes. Procedure: fill the bottle, wait, gently swirl the water, and drink. Consider this principle as a brand claim, not a health effect.

Triangle

Is the Flaska BPA-free and what materials is it made from?

Yes. Glass is naturally BPA-free and free from plasticisers, and it is inert (does not react with the beverage). The accessories mainly consist of cork and neoprene sleeves for protection and easy carrying.

Triangle

Can I wash the Flaska in a dishwasher?

Not recommended. Maintenance is manual – use a soft brush and a mild detergent. This way, both the bottle and the sleeve will maintain a longer lifespan.

Triangle

What about hot water – can I pour hot drinks into the bottle?

Hot drinks may reduce the declared "structuring" effect. Recommendation: prepare the hot drink separately and let it cool, or use special cups/glasses designed for hot drinks (information on "water tuning" is a manufacturer's claim).

Triangle

How durable is the bottle and what should be avoided?

Glass is robust, but remains a fragile material. We recommend a protective sleeve, avoiding drops and impacts, not using in a microwave, and avoiding extreme temperature shocks.

Triangle

What sizes and accessories are available?

Zakladatel slovinské značky Flaska, Maks Vrečko, je skutečný inovátor. Na nápad, který za Flaskou stojí, přišel při pěstování jahod. Pomáhal totiž manželce na jejich rodinné farmě. Protože ho typické zemědělství nezajímalo a klasické zemědělské technologie moc neznal, začal se zajímat o různé netradiční přístupy. V roce 2003 se díky tomu seznámil s procesem restrukturalizace vody. Rozhodl se provést vlastní pokus - polovinu pole zaléval restrukturalizovanou vodou a druhou polovinu normální vodou.

Nějakou dobu nebyly patrné žádné výrazné rozdíly, ale když nastal čas sklizně, rychle se ukázalo, že voda hrála důležitou roli. Jahody zalévané restrukturalizovanou vodou byly znatelně pevnější. Trvanlivost plodů se prodloužila a úroda na části pole, která byla zalévaná restrukturalizovanou vodou, byla o 18,1 % vydatnější. Na konci sezóny byly rostliny v této části výsadby vitálnější a méně napadené chorobami.

V následujících letech pak Maks v experimentech s restrukturalizovanou vodou pokračoval. Ze skeptika se stal nadšencem této technologie, která je známá již téměř 90 let, od objevů Viktora Schaubergera, průkopníka strukturování vody. Maks říká, že když nad tím zpětně přemýšlí, mělo to být naprosto logické, že zlepšení struktury vody povede i ke zlepšení jahod, vzhledem k tomu, že 89 % plodu jahod je tvořeno vodou. V té době ho to prý ale vůbec nenapadlo. 

K údivu mnohých Maks v roce 2009 přestal pěstovat jahody. Měly vynikající kvalitu, odbyt byl skvělý a všichni byli spokojeni. Ale život mu říkal, že se musí poohlédnout po nových výzvách. Začal nabízet technologii strukturování vody v zemědělství. Přes vynikající výsledky testů (při pěstování ovoce, zeleniny, výrobě mléka, chovu drůbeže atd.) nebyl trh ještě připraven přijmout "neviditelnou" technologii, přestože její výsledky byly zcela zřejmé.

Po náročném roce a půl dostal nápad implementovat technologii strukturování vody do lahve pro každodenní použití. V listopadu 2009 byla spuštěna testovací série a po kladném ohlasu byla zahájena skutečná výroba. A tak se zrodila - Flaska! Na slovinský trh vstoupila 10. března 2010.

Věci se začaly hýbat kupředu rychlostí blesku - tým Flasky se rozrůstal, a brzy uváděli na trh nové modely a velikosti lahví a expandovali na nové světové trhy. Vypadá to jako pohádka, ale v reálném životě Flasku také čekaly těžké časy, zejména v letech 2012 až 2014. Toto období překonali jen díky společné práci a spoustě pozitivní energie všech  zaměstnanců a partnerů. V následujících letech pak vyvinuli další naprogramované výrobky - džbán Vodan, Doggy Flasku pro psy a sklenici na pití Sirius.

Flaska nadále zdokonaluje proces restrukturalizace vody TPS. Jejich filozofie restrukturalizace vody se liší od většiny ostatních, které tuto technologii nabízejí. Pomáhají vodě vrátit se k její pramenité struktuře. Společnost Flaska zastává názor, že všichni obyvatelé naší planety by měli pít vodu co nejlepší kvality. Výrobou Flasky tak nejen zvyšují obecné povědomí o pití kvalitní vody, ale přispívají ke snižování vytváření plastového odpadu jednorázovými plastovými lahvemi. 

Flaska je důkazem toho, že máme moc měnit svět prakticky každým douškem vody, kapku po kapce.
