There is something oddly satisfying about drinking cold water, especially when you’re a few hours into a ride. As temperatures rise, so will the water/drink mix inside your bottles, so like most cyclists we use insulated water bottles in summer. However, by their nature, insulated water bottles are larger and heavier more than traditional bottles. If you’re a weight weenie who counts each gram but still wants to enjoy cold beverages, Elite has you covered with their latest NANOFLY insulated water bottles. Based on the popular FLY bottles, the NANOFLY utilizes ultra-light Nanogel structure to achieve upto 4 hours of thermal insulation. Elite claims the NANOFLY is the “world’s lightest thermal bottle” with a claimed weight of only 109g (note weighed 118g on our scales) with a 500ml capacity.

The Elite NANOFLY bottles can keep your liquids cold for multiple hours without the weight of traditional insulated bottles.

If you are looking for some unboxing therapy, you’ll be disappointed with this one. We received the three (note, the 500ml size is the only size) color variations currently available for the NANOFLY. Each bottle came with a simple cardboard tag with some basic information about Elite which is easily removed by popping off the nozzle from the cap.


Elite has kept the design of the NANOFLY bottles quite similar to the FLY bottles it’s based on. That means the NANOFLY has simple and straight lines with a constant diameter around the main body with a indentation near the center to match the tabs on standard water bottles. The bottle also features the standard 74mm diameter which means it fits snug and securely on most water bottle cages. In addition to adding style, the vertical ridges in the main portion of the bottle help make the NANOFLY slip less when being held. What’s impressive is the Nanogel insulation material that keeps the bottles light and nearly as soft and squishable as the FLY bottles.

Elite NANOFLY - Squishy
Despite being an insulated water bottle, the NANOFLY still features Elite’s signature squishable design.

In terms of nozzle and cap, the NANOFLY utilizes the same basic push-pull mechanism as the FLY. Color matched with the body of the bottle, the cap has a flat top and thin design. The large diameter nozzle for high-flow is surrounded by soft rubber surround. One of the big perks of this design is that it’s easy to clean and only has two parts: the removable nozzle tip and the cap. It lacks some of the features of the multi-piece and complicated membrane style caps of the CamelBak Podium or Polar Breakaway but makes up for it by being very easy to clean and drink from. Note, there is no locking mechanism on the cap so while you can close them by pushing down the valve you should pack them carefully to prevent them from opening.

Elite NANOFLY - Cap
As with the other FLY bottles, the NANOFLY have simple push-pull nozzles that are easy to clean.

While we’ll have to come back in the summer to do a proper thermal comparison against other insulated bottles, we found the NANOFLY lived upto its multi-hour insulation claim. Even after multi-hour rides, the fluids remained cold and refreshing. While the NANOFLY is a light bottle, don’t expect to win any PRs just because of them. They tipped our scales at 118g (a few grams heavier than claimed) which is only 6g lighter than the ICE FLY we’ve previously reviewed. Taking into the fact that the NANOFLY has double the thermal effect of the ICE FLY, it is an impressive achievement.

Elite NANOFLY - Comparison
Aside from the vertical ridges, the NANOFLY is visually quite similar to the other FLY bottle variations and even the biodegradable JET with sharp modern lines.


Overall, we found that the Elite NANOFLY water bottles have great insulation properties yet still remain flexible and squishable. Although we don’t know if the NANOFLY really is the lightest insulated bottle in the world, it’s lighter than similar insulated bottles we’ve reviewed. It’s only available in a 500ml capacity currently, but with the three color variations and simple branding, the bottles look great on any bike. While the retail price would suggest there is gold leafing or perhaps a crystal bedazzled Elite logo on the bottle, at least at the time of this review it’s available for nearly half price at many retailers. At a discounted price, the NANOFLY is a great option for those looking for an insulated water bottle that’s still squishable and doesn’t add too many grams to your bike.
