A million plastic water bottles are purchased every minute in America, but only a fourth of them actually ending up in the recycling bin. It’s about time to kick the single-use-plastics habit in the hopes of slowing down the world’s exponentially increasing plastic problem.
In honor of World Oceans Day on June 8, hydrate with a reusable water bottle at the beach, catch your morning buzz in a stylish glass coffee cup, and devote your efforts to sustaining a plastic-free lifestyle to maintain the beautiful island that we (sometimes) take for granted.
Here are eight stylish additions to your collection of eco-friendly alternatives that you can grab at stores or order online:
Anthropologie bottle

Blame TikTok. Blame Instagram Reels. Blame my continuous habit of leaving my Basic B***h bottle everywhere around the UFC gym. I need monogrammed objects in my life. My fourth and absolutely not my last visit to Anthro this month saw me walking out with a new pastel bottle with a big ‘ole “K” on it. Will I put water in it? Will I put a Jennifer Aniston-approved smoothie in it? Or will I sneak pre-mixed cocktails into the movies with my hidden bag of kakimochi? A lady never tells.

Hydaway

If a clanky, bulky water bottle doesn’t suit your on-the-go hydration needs, opt for a Hydaway, a collapsible silicone water bottle. The ultra-stash-able BPA-free bottle that flattens to a 1.5-inch-thick disk is a lightweight option you can take on hike, walk or daily commute to work, and then pack away into a small purse or backpack. If you suffer from a perpetually empty Brita at home, Hydaway also offers carbon filters for its water bottles that filter tap water on the go.

Nick Kuchar Camp Mug

Bringing a local touch to this list are these stylish BPA-free camping mugs designed by O‘ahu-based artist Nick Kuchar. This double-walled “Kailua” mug comes with a sippy cup-style lid so you can discretely enjoy your adult juice at picnics, beaches, campsites or while you’re out walking the pup. While you’re browsing Kuchar’s retro-inspired art, take a look at the “Ko‘olau Dreamin’” mug and the “Hawaiian Islands” 32-ounce vacuum insulated bottle.

Another alternative to a plastic bottle, Que collapsible bottles are recycled BPA- and plastic-free bottles perfect for hydration without the bulk. Suit your style with 16 different color choices, from citrus yellow to frozen plum to metallic charcoal. Feel good about the plastic water bottles you’re saving and the donation made to The Rainforest Trust, a nonprofit dedicated to safeguarding 17.6 million acres of wildlife habitat worldwide, from every Que bottle purchased. We’re excited about getting our hands on one of the new insulated bottles (ceramic interior, bamboo and stainless steel lid, cute AF) that came out in the fall of 2020.

Corkcicle Canteen

If you need to take your homemade batch of sangria to a get-together, get a local brew to-go or are just really, really thirsty, grab one of Corkcicle’s Canteens. The canteen keeps your cold liquids cold for more than two days and hot liquids hot for half a day with a triple insulated design. If you don’t quite need the large canteen size, opt for a 9-, 16- or 25-ounce style. Pick a canteen (or coffee mug, or tumbler, or stemless wine tumbler) from collections like the blue or purple iridescent “Dragonfly” collection or the floral Rifle Paper Co. And have you seen the flat canteens?
Editor’s tip: Looking for a unique gift? Corkcicle’s 25-ounce canteens are perfect for you and your wine-loving friends as they only hold an entire bottle of wine. Time to step up your boozy picnic game.
Canteens start at $23.96 and range from 9-ounce bottles to 60-ounce bottles, The Refinery, Kāhala Mall, corkcicle.com
