Frequently Asked Questions

What is 316L stainless steel and why is it better for water bottles?

316L is medical-grade stainless steel containing 2-3% molybdenum for superior corrosion resistance. Unlike 304 (18/8) steel, 316L resists acidic beverages without metallic taste. It meets ISO 5832-1 medical implant standards.

How does the no-screw lid work?

Press-and-release mechanism — open one-handed in 2 seconds. Double-seal, triple-lock = 100% leak-proof. Lid separates into 3 pieces in 3 seconds for mold-free cleaning.

Can I put coffee and acidic drinks in this bottle?

Yes. 316L is specifically designed for acidic beverages — coffee, tea, lemon water — zero metallic taste.

Is 316L stainless steel safe for baby formula?

Yes. 316L is the same medical-grade steel used in surgical implants. It contains 2-3% molybdenum for superior corrosion resistance, making it completely safe for baby formula, breast milk, and all beverages — with zero metallic leaching even at high temperatures.

How does Hikesity compare to Hydro Flask and Stanley?

Hikesity uses 316L medical-grade steel for the inner lining, while most competitors (including Hydro Flask and Stanley) use standard 304 food-grade steel. 316L offers better corrosion resistance and zero metallic taste. Plus, our patented no-screw lid opens one-handed in under 2 seconds — no twisting required.

Can I put carbonated drinks in this bottle?

Yes, the 316L stainless steel interior handles carbonated beverages without any issues. The no-screw lid creates an airtight seal that maintains carbonation. Just open carefully as pressure may build up — we recommend pointing the lid away from your face when opening a carbonated drink.

What is the warranty on Hikesity bottles?

Hikesity bottles come with a lifetime warranty covering manufacturing defects. If you experience any issues with insulation performance, the no-screw lid mechanism, or the steel body, contact our support team for a replacement.

Does Hikesity ship free to the USA?

Yes. Free shipping to USA and Canada.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.
