Nine athletes tested - 5 men and 4 women. 28oz bottle and a 1.5 liter regular Crystal Geyser water bottle from the grocery store. Link to the YouTube video is down in my signature, but here are the results:
Note: Weights are combined athlete and all equipment. Watts are based on race pace for each individual athlete.
Tony - 180cm, 83.1 kg
Obviously interesting results. Keeping the bottles high on the chest is key even though it may pull down the neck line. Unless it's a low neck line, in which case it'll kill you, which is covered in the video when we tested an athlete who came after our testing for this was complete. I questioned the results, but they were consistent and gel with what others are finding around the world. In fact, I've been jokingly asked to stop giving away secrets.
Keep in mind this is real world testing using an AeroLab sensor. We're measuring the differences as they're happening. For instance, Adam was going ~ 1km faster for the same power output and wind conditions with his drag savings. Impressive.
Other notes: The 28 oz bottle was empty, and the 1.5 liter bottle was about 1/3 way full (or 2/3 the way empty depending on your demeanor). All athletes tested at their race pace wattage.
Aero socks and calf sleeves are next. I wouldn't expect the same consistency in the results from that testing, but we may have found an interesting correlation for those who see a drag savings and those who don't. Oh, and we have a newly released aero shoe we're testing next week! Stay tuned.

Tony - 180cm, 83.1 kg
- 28oz Bottle (high on chest) = 2.31% drop in drag / 6 watts
- 28oz bottle (low on belly) = .46% drop in drag / 1.2 watts
- 1.5 Liter bottle = 6.02% drop in drag / 15.6 watts
- 3 liter Camelbak bladder only = 4.17% drop in drag / 10.8 watts
- Camelbak bladder + 28oz bottle stacked (see video) = 8.8% drop in drag / 22.9 watts
- 28oz bottle = 2.31% drop in drag / 3.9 watts
- 1.5 liter bottle = 5.56% drop in drag / 9.4 watts
- 28oz bottle = 3.19% / 5.7 watts
- 1.5 liter bottle = 1.59% / 2.9 watts
- 28oz bottle = 4.7% / 11.8 watts
- 1.5 liter bottle = 8.55 / 21.4
