Bird Design Glass Water Bottle neoprene cover • water restructuring • programmed glass • 0.5 l
FLASKA glass water bottle with Bird motif (500 ml) is built around patented “programmed” TPS glass. According to the manufacturer, the glass can “revitalise” water within a few minutes; in practice, users most often describe a smoother, more balanced taste, even when using tap water. This is precisely why FLASKA is priced higher than standard glass bottles. The manufacturer describes this effect as supporting a more consistent drinking routine and a perceived sense of improved hydration and increased energy.
Bird Design Glass Water Bottle – Flaska
Glass water bottle made from European glass, suitable for everyday use. It works well for older children at school and on trips, for workouts, at the office and in leisure time; it has a pink neoprene sleeve that improves grip and feels comfortable to hold.
Flaska uses programmed glass technology (TPS), described as an adjustment of the water structure toward the character of spring water.
European glass is chemically stable and naturally BPA-free (bisphenol A), and it does not retain odors or flavors. Bisphenol A is a synthetic substance used in some plastics; it can migrate into drinks and is regulated in the EU.
Leak-proof cap and a replaceable neoprene sleeve make this bottle a reliable choice for school days, trips, sports – and at home.

How are Flaska bottles different from “ordinary” bottles?
Compared with plastic bottles, Flaska offers the benefits of glass: it is chemically stable, so it does not retain odors or flavors and does not absorb colorants from beverages.
Glass is also naturally BPA-free and contains no plasticizers, while plastic may pick up smells or release compounds into drinks with long-term use.
From a hygiene standpoint, glass is easy to clean and tolerates hot water and thorough brush cleaning without forming a film on the surface. Plastic, by contrast, can scratch more easily, and micro-scratches may reduce washability and make it harder to keep clean.
In the product life cycle, a glass bottle can have a long lifespan with careful handling and is fully recyclable, which reduces the need for single-use packaging. Plastic may be lighter, but it typically has a shorter useful life and can struggle to stay taste-neutral over time.
In practice, glass is heavier and more fragile, but Flaska balances this with accessories. Cork and neoprene sleeves are available, and bottles come in several sizes, making it easy to choose a version for work, sport, travel, and home serving.

Who are Flaska bottles for, and where can you use them?
Flaska bottles are suitable for daily hydration at home, in the office, at school, and in meetings. They work great for sports and leisure – for fitness, yoga, hiking, and cycling. Flaska also offers kids’ bottles to help support a regular drinking routine at school and during activities.
They are practical for travel and everyday commuting – in a backpack or car, on a trip, or around town. You can easily refill the bottle at water fountains or at home before you leave, so you have water always at hand.
Flaska bottles are made in a variety of designs with an integrated sleeve, so you can choose a style that matches your taste and preferences. Options include cork, neoprene, and silicone sleeves, in a range of colors and motifs for kids and adults. The sleeve improves grip and completes the look; neoprene sleeves are removable and washable, while cork and silicone sleeves can be easily removed and wiped clean with a damp cloth.
Why choose Flaska
Flaska bottles are reusable glass bottles that keep water taste-neutral and free from unwanted odors. Glass is inert and naturally BPA-free, so it does not react with beverages and does not release anything into them.
The brand’s identity also includes an approach the manufacturer calls “programmed glass” – its own way of focusing on quality and the experience of water.
Flaska bottles fit easily into everyday hydration at work, at home, while studying, and on the go. Thanks to a comfortable neck and a quality cap, they are easy to clean and pleasant to drink from.
The brand offers several bottle sizes and different design options with cork, neoprene, or silicone sleeves. Sleeves improve grip and finish the look; neoprene sleeves are also removable and washable, while cork and silicone sleeves can be easily removed and cleaned.
For a long lifespan, hand washing with a gentle detergent and regularly airing out the cap are recommended. Reusing a glass bottle helps reduce single-use plastic packaging.

FAQ
What is Glass & Vibe technology and how should I use the bottle?
The manufacturer states that a vibration program is imprinted into the glass, which should “tune” the water in about 5 minutes. Steps: fill the bottle, wait, gently swirl the water, and drink. Treat this as a brand claim, not a health effect.

Is Flaska BPA-free and what materials is it made from?
Yes. Glass is naturally BPA-free and free from plasticizers, and it is inert (it does not react with beverages). Accessories mainly include cork and neoprene sleeves for protection and comfortable carrying.

Can I wash Flaska in a dishwasher?
Not recommended. Care is hand wash only – use a soft brush and a gentle detergent. This helps the bottle and sleeve last longer.

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 dedicated cups/glasses intended for hot drinks (the “tuning” information is a manufacturer claim).

How durable is the bottle and what should I avoid?
Glass is sturdy, but it remains a fragile material. We recommend using a protective sleeve, avoiding drops and impacts, not using it in a microwave, and avoiding extreme temperature shocks.

What sizes and accessories are available?
The brand offers several bottle sizes and a wide range of accessories. Available options include replaceable sleeves (cork, neoprene), replacement caps, and other everyday add-ons.

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.
