• Thinksport Mineral Sunscreen SPF 50+, 3 fl oz

  For exposed walks and shoreline time. The Amazon listing checked on Nov 7, 2026 is titled Thinksport Mineral Sunscreen SPF 50+ Zinc Oxide, 3 fl oz. That listing text says the formula uses zinc oxide (it states 24.25%) and lists oxybenzone among ingredients it does not contain. It did not explicitly say octinoxate in the text reviewed. Hawaiʻi Revised Statutes §342D-21 makes it unlawful to sell or distribute sunscreen containing oxybenzone or octinoxate in the state without a prescription. Read the current tube before you buy. Listing text changes.

• Nalgene Tritan Wide Mouth BPA-Free Water Bottle, Cadet, 32 oz

  For trails whose managing agency says there is no drinking water, or that stream water should not be drunk. The Amazon listing checked on Nov 7, 2026 is titled Nalgene Tritan Wide Mouth BPA-Free Water Bottle, Cadet with Cadet cap, 32 oz. The listing describes a BPA-free Tritan bottle. This is one colorway, not a claim that every Nalgene bottle is the same product.
