Widepac & Tube Insulator Winter Kit

This basic Winter Hydration Kit comes complete with a Widepac 3L Hydration System, our fitted Widepac Insulator and the Insulated Drinking Tube Kit featuring our Storm Push-Pull Valve, offering full hydration flow also at low temperatures.

Widepac 3L

Our classic Hydration System with the wide opening and air-tight sliding closure. Low maintenance, zero taste - best in test for years!

Widepac Insulator

This zippered insulating sleeve adds 3mm foam insulation and protection to any of our Widepac hydration systems. Lab tests showed freezing and heating are slowed down by 50%.

Winter Tube Kit

Insulated Drinking Tube with our Storm Push-Pull Drinking Valve. As the silicone of the standard SOURCE Helix Bite Valve can freeze and get stiff at extremely low temperatures, the Storm Push-Pull Valve will not fail you even in freezing temperatures, giving you full hydration flow.

Hydration Tip for Winter

Whichever Hydration System you choose: We recommend blowing air into the drinking tube every time after drinking. This way your water (or energy drink) is pushed back into the reservoir, making sure no water will freeze and block the tube.

SOURCE Hydration technologies

Widepac Closure (U.S Patent No. 7,648,276,B2) - The original user-friendly Widepac™ Slide Closure opens wide, allows easy filling, cleaning, draining, and ice insertion. Airtight seal. Most SOURCE Hydration Systems and Hydration Packs feature reservoirs with our signature Widepac Closure.

Taste-Free™ System - Our co-extruded PE film retains the pure taste with absolutely no plastic flavor, also over time. (BPA and Phthalate free.)

GrungeGuard™ Technology - Our GrungeGuard™-Technology inhibits bacteria growth on the reservoir and drinking tube for the life of the system. Technology utilizes FDA-approved and EPA-registered anti-microbial agent. 

Glass-Like™ Technology - SOURCE's Glass-Like™ Film is 2000% smoother than standard TPU films, with virtually no difference from glass itself. This multi-layer Polyethylene film, manufactured in accordance with SOURCE's Glass-Like™ technology, prevents bio-film build up, making the system virtually self-cleaning.

Easy Care & Low Maintenance - Glass-Like™ technology combined with Grunge-Guard™ technology represents a new generation in hydration systems, in which cleaning is no longer an issue! Simply refill with water and drink again and again without special care. Water will remain fresh for days and even weeks.

Well delivered and satisfactory performance
Product was delivered really fast. I have used it twice in temperatures around -5 to -10 celcius while skiing and liquid temp was ok until almost the end of the full day (i am rather sensitive with cold liquids so at around 4-5 pm it was a little cold for my taste.)

Still, without the winter cover in both bag and tube i would not be able to use it in the mountain after a couple of hours. So, all in all it was a good and useful purchase.

" Our tester left water in the Widepac for eight weeks without cleaning and reported no stinky taste or smell."
" More to love: The top opens wide like a paper bag for rapid filling. "

Source Widepac Hydration System

" Filling up Source bladders is easy thanks to the wide opening."
" The Helix is drip-free, and very easy to drink from. "
" It is one of the easiest to use thanks to its nearly self-maintaining properties, and it is completely taste-free."
