Iceland's Sky Lagoon Is a Wellness Haven — Here's What to Pack For It

Stojo Collapsible Water Bottle ($20)

Sky Lagoon has an in-water Gelmir Bar built into the area of its geothermal pools where visitors can indulge in some wine, water, or refreshing juice and pay via their wristband (no loose cash needed). But after the treatment, you might experience a little dehydration, which is why having this water bottle tucked into your travel bag will be so essential. It has a cool collapsible design, so when you're finished drinking from it, you can squeeze the bottle down and maximize your packing space. Plus, Iceland has some of the cleanest tap water on Earth, so you can fill this bottle in a standard sink and skip having to pay for a new one throughout your trip.

Beyond this collapsible water bottle, I have also tried and reviewed Stojo's collapsible coffee mug.
