Necessity is clearly the mother of invention. Pitotubes are refillable travel bottles ideal for decanting your lotions and potions for lighter, more compact and better-organised travel. Their best selling point, however, is that the bottles use a sealed, airless pump to prevent leakage during air travel. They are the brainchild of former flight attendant Alisa Caviness-Driscoll, who noted how many fellow travellers and crew members complained about their ruined luggage.
Pitotubes can be refilled countless times; remove the silver outer cap, unscrew the inner cap and pour in the product. Fill to the top to ensure a good seal because the piston pump will activate only when the liquid touches it. To refill, push the piston from the top of the bottle back down to the bottom.
The airless pump ensures every last drop of your expensive moisturiser is pumped out of the bottle onto travel-weary skin.
The recyclable plastic tubes contain less than 85ml, meeting current US Transport Security Administration requirements.
Pitotubes cost US$10 each or come in a US$59.95 travel kit, which contains six bottles (two 50ml, two 30ml and two 15ml), providing sufficient content for a three- to four-week holiday. Travellers can customise their bottles using the blank labels provided with the kit. The bottles are stored in a metallic-blue, wire-mesh travel bag.
