Winter Water Bottle Insulation Hack: Neoprene Camera Lens Holder
Insulated winter water bottle holders capable of holding 32 oz wide mouth bottles are in very short supply this year. The best-insulated carriers from Forty Below, Mountainsmith, and Outdoor Research are either sold out or back-ordered due to supply chain delays.
Here’s an alternative product, the XL Powerextra Neoprene Camera Lens Holder, that makes an excellent insulated winter water bottle carrier. This was suggested to me by a SectionHiker reader and it is an excellent hack, one that vies in quality and effectiveness with the above-mentioned insulated carriers that are specifically designed for the task. It’s also less expensive than those other insulated water bottle options.
Specs at a GlanceMaterial: 8 mm neoprene (waterproof, insulating)XL Size dimensions: 9.64″ x 3.74″Cap: YesHip Belt Webbing: YesThe Powerextra Neoprene Lens Case (XL) can fit a 32-oz wide-mouth Nalgene bottle.
The Powerextra Camera Lens Holder can only be ordered in a 4-pack that contains lens holders in several sizes. The largest of these (the XL) is the one that’s compatible with wide-mouth Nalgene bottles. It also has all of the attributes that make a good insulated winter water bottle holder.
Insulated capTwo zipper sliders with large zipper pullsWebbing strap that you can slide over your hip belt
The XL lens holder can securely hold a 32 oz wide mouth Nalgene bottle (the milk white one), which is what I recommend using for carrying hot water for drinking on winter hikes. If you fill these bottles with boiling hot water in the morning when you wake up before your hike, they’ll cool off enough to be drinkable later in the day using the short term/long term water transport methodology I describe in Winter Water Bottle Insulation and Hydration: A Simple Approach.
The Lens Holder has a webbing strap sewn along one side.
Neoprene Camera Lens Holder
If you search the internet for insulated water bottle holders, you’ll find many that are open at the top and don’t have an insulated cap. They’re intended to keep drinks cool, not as hot as possible. You really want an insulated bottle holder with a cap for complete insulation.
The Powerextra Lens Holder has an insulated cap made with the same 8mm Neoprene as the rest of the holder. The cap is sewn on securely, so the lens holder is all one piece. It closes with two zipper sliders, not one, so if you break one, you have a fallback. Not having a zipper is preferable because it’s more durable (See: Why Zippers Fail) but the Neoprene Bottle Insulators from 40 Below that close with velcro are unavailable this year or in short supply and this is a good alternative.
The webbing strap is long enough that you can slide the Len Holder into your hip belt.
The Powerextra Camera Lens Holder also has a webbing strap sewn along one side. It is long enough that you can slide it over your hip belt and hip belt pocket, or use a carabinier, or some other attachment scheme to attach it to your hipbelt. Alternatively, you can slide it into a side water bottle pocket on your backpack and carry it that way. I prefer carrying my insulated bottle holder on the back of my hipbelt (as shown above), out of the way, but you should experiment with what feels right for you.
While this is an unconventional use of a Powerextra Camera Lens Holder for insulating a winter water bottle, it’s a neat hack if you can’t find another insulated bottle holder this year or simply want to pay less for one. I have no idea what you’ll do with the other three lens holders that come in the 4-pack that includes the XL size shown above, but I’m sure you’ll think of something!
