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

Hiearcool Waterproof Phone Pouch ($10, originally $20)

If you want to fully lean into this Icelandic wellness treatment, I recommend leaving your phone behind in a locker. But if you (like me) can't resist documenting the experience, this waterproof phone pouch will be your most important buy prior to landing on the island. It conceals your phone in an airtight pouch that's designed to mitigate water damage, while still giving you the ability to use your device through the material. I kept my iPhone tucked in this pouch throughout my whole treatment, and still had no trouble taking photos or videos. It also features a wrist strap, which is especially helpful if you choose to get a drink while in the geothermal pools (I recommend the juice) and find your hands full.
