Dehydration Comes Easy When Skiing: Collapsible Water Bottle Is An Answer.

Staying hydrated on the slopes is important, but rigid plastic water bottles are a pain to carry in a parka. Hydrapak makes soft and pliable water bottles that fit comfortably in the pocket.

We tested Hydrapak’s half-liter SoftFlask sports bottle over a few days on the hill. The 500-ml version held enough water without crowding a chest pocket, and it fit the palm securely. Made of BP-free thermoplastic polyurethane, it had no noticeable off-taste for some users. The company says it’s developing “no-taste” containers for sensitive palates.

The plastic cap is a bit unwieldy, and it took some practice to twist the valve open and closed. But it seals tightly with no leaks. A rubber nipple makes it easy to take a swig when the valve is open. The flask collapses to a small fraction of its size when empty. It retails for $20.

Hydrapak sells larger flexible water bottles with an ingenious design. These 750-ml and 1-liter Stash bottles resemble a Nalgene bottle but don’t take up valuable real estate inside pack or pocket when drained. They stand up full or empty, thanks to a rigid top and bottom, yet can be twisted and folded into a small disk when empty. The 1-liter retails for $23.

Most of Hydrapak’s business is with brand partners, notably Osprey Packs, which

incorporates the company’s reversible water reservoirs into backpacks with drinking tubes. The smaller flasks are for runners, skiers and anyone looking for a compact water container. Dishwasher-safe, they’re just as easy to hand-wash with mild soap.

Hydrapak claims its sports bottles are rugged enough to survive being run-over by a car. These portable, collapsible reservoirs work well. Now there’s no reason for not hydrating throughout an active ski day.
