Learn what the Ocean Bottle x GROUNDTRUTH RIKR Bottle Bag carries, how to attach it, and how to pack it for commutes and day trips without spills or strain.
Quick answer
The Ocean Bottle x GROUNDTRUTH RIKR Bottle Bag is a hands-free carry accessory for Ocean Bottle products, available in Eco-X Black and Stone Brown. It is designed for daily commutes and day trips, but it is not a universal sleeve: check your bottle's diameter and lid before you rely on it. Pair it with a leak-proof lid setup and load it last so the bag stays balanced.
Before you pack: confirm your bottle and lid will work
The RIKR Bottle Bag is built for Ocean Bottle products, so the most reliable starting point is an Ocean Bottle you already own. If you use a different brand, measure the widest part of your bottle and compare it to the bag opening rather than assuming a fit. The bag is not described as adjustable, so a bottle that is too wide or too tall may sit awkwardly or not seat at all.
Lid choice matters as much as bottle size. A lid that sits flush keeps the profile low and reduces snagging. If you use the Brew Lid, note that it is listed with a 350ml size option, which tells you it is intended for a specific bottle size rather than every Ocean Bottle. Do not force a lid that does not seat fully, because a partially closed lid is the most common cause of leaks inside a carry bag.
How to attach and wear the RIKR Bottle Bag
The bag is designed for convenient, hands-free carrying, so attach it before you fill your bottle. That order lets you test the strap or attachment point without extra weight pulling the bag off balance. Once attached, tighten any adjustable connection so the bag sits close to your body; a loose bag swings, and swinging is what usually knocks a lid loose over a long walk or commute.
If you plan to carry the bag on a bike or on public transport, keep the bottle upright and the lid on top. The bag is described as durable for daily commutes, but durability does not mean it is waterproof, so treat rain exposure as a limitation and keep electronics in a separate pocket.
What to put in the bag beyond the bottle
The RIKR Bottle Bag is a bottle bag first. Add small flat items like a card, a key, or a folded cloth only if they do not press against the bottle and push the lid. Bulky items change the shape of the bag and can make the bottle sit at an angle, which is exactly when leaks happen.
For day trips, pack the bottle empty and fill it at your destination if you want to reduce weight. If you carry a funnel or spare lid, the Peak Funnel & OG Lid is a practical companion because the integrated funnel lets you refill from a tap or fountain without splashing, and the OG lid gives you a secure seal when you are done. Keep the funnel dry before you store it next to the bottle, since a wet funnel adds moisture inside the bag.

Cleaning and storage between uses
Empty the bag after every trip and let it air dry fully open. A bottle bag that stays damp develops odor, and odor is harder to remove than to prevent. Wipe the inside with a damp cloth and mild soap, then dry it away from direct heat, because heat can distort the fabric and change how the bottle sits.
Store the bag unstuffed rather than with a bottle inside. Keeping a bottle in the bag long-term can stretch the opening and reduce the snug fit that keeps the bottle from shifting. If you rotate between colors, the Eco-X Black and Stone Brown options are both listed, so choose the one that matches the rest of your carry rather than buying both for the same bottle.
How to set up and use the RIKR Bottle Bag
- Match the bag to your bottle: Check that your bottle is an Ocean Bottle product or measure its widest point against the bag opening before you rely on the RIKR Bottle Bag. If the bottle does not seat without forcing, the bag is not the right carrier for that bottle.
- Choose and test your lid: Fit your lid, fill the bottle with water, and turn it upside down over a sink before it ever goes in the bag. Use a lid sized to your bottle, such as the Brew Lid's 350ml option, and confirm the seal is snug. A lid that passes the upside-down test is the single best leak prevention step.
- Attach the bag before loading: Fasten the bag to your body or bag first, then tighten any adjustable connection so it sits close and does not swing. A swinging bag is what knocks lids loose, so fix the fit before adding weight.
- Load the bottle upright and keep extras flat: Slide the bottle in lid-up, then add only flat items that do not press on the lid. If you carry the Peak Funnel & OG Lid, dry it first and store it beside the bottle, not on top of it. Bulky extras tilt the bottle, and a tilted bottle is more likely to leak.
- Empty and dry after every use: Remove the bottle, wipe the inside with mild soap and water, and air dry the bag fully open away from direct heat. Drying prevents odor and keeps the opening snug, which protects the fit over time.
Product facts
- Ocean Bottle x GROUNDTRUTH® RIKR Bottle Bag: The Ocean Bottle x GROUNDTRUTH RIKR Bottle Bag is compatible with Ocean Bottle products for convenient, hands-free carrying and is available in Eco-X Black or Stone Brown. If you already own an Ocean Bottle, this is the lowest-risk fit; if you carry a different brand, verify the size before buying because the bag is not described as universal.
- Peak Funnel & OG Lid: The Peak Funnel & OG Lid fits Ocean Bottle reusable water bottles with a snug, leak-proof seal, and the integrated funnel allows smooth transfer of liquids without spills. It solves the two biggest bag problems: messy refills and a lid that loosens, so the bottle stays sealed while it rides in the RIKR bag.
- Brew Lid: The Brew Lid is offered in a range of colours and a 350ml size option, including Ice Blue, Lavender Haze, Obsidian Black, Ocean Blue, Rock Grey, Sky Blue, Sahara Red, Sand Stone, and Shale Green. The 350ml size option signals it is intended for a specific bottle size, so match it to your bottle rather than assuming it fits every Ocean Bottle.
