Detailed Review

The Sweet Protection Tucker III 2Vi® Mips Helmet is an aero helmet that’s stealthy, for those who don’t want the tell-tale aero helmet design tipping off their competition. This helmet is also for those who prefer a more road-styled helmet or don’t like the giant visor or tail that’s common with aero helmets.

The Sweet Protection Tucker III 2Vi® Mips Helmet was developed with expertise from a Formula 1 aerodynamicist and in collaboration with the Uno-X Mobility Cycling Team. This aero cycling helmet is best for use in breakaway positions, solo efforts, and sprints, being optimized for speeds between 45 km/h and 50 km/h.

For transparency, I’ve been focused on mountain bike riding since receiving this helmet because my A-race, an off road triathlon, was mid-April. This review will reflect the fit and feel of the helmet but won’t go into aero functionality. Since I was on my MTB, I didn’t manage to get up to the 27-30 mph optimization (to be fair, I would only be this fast going downhill on my TT bike or in a pretty stiff tailwind), so I cannot comment about aero benefits or how it feels at speed.

The Sweet Protection Tucker III 2Vi® Mips Helmet fits true to size. I am generally a size small in most helmets, and I found that a size small-medium for the Tucker III fits me well. The Mips and 360 Occigrip Fit System didn’t have any places that snagged my hair or had pressure points that created discomfort. Once tightened down, I really didn’t notice the helmet, which is a good thing.

The chin strap also fits well. Sometimes, helmet straps fit oddly around my ear or aren’t comfortable under the chin. I found that the Sweet Protection Tucker III 2Vi® Mips Helmet straps fit me well out of the box and that the strap was comfortable, even on rocky descents.

The Sweet Protection Tucker III 2Vi® Mips Helmet worked well with a variety of sunglasses for me (Sweet Protection and other brands).

One of my pet peeves with aero helmets is that it’s really easy to overheat while wearing them because they usually don’t offer much in the way of ventilation. I did manage to get in a hot + humid MTB ride in Austin, with temperatures in the 80s. While I wasn’t going all that fast, I did have plenty of air flow from the rounded vents (front and back) and internal ventilation structure, and my head didn’t feel hot.

Closing Thoughts

The Sweet Protection Tucker III 2Vi® Mips Helmet, with my early testing, has proven to be a comfortable aero helmet that allowed me to be flexible with my eyewear selection and had plenty of ventilation to keep me cool. I have a few traditional road triathlons (i.e. TT bike) ahead of me this summer and look forward to continued riding and testing of the Sweet Protection Tucker III 2Vi® Mips Helmet.

The Sweet Protection Tucker III 2Vi® Mips Helmet is available in 5 colorways and in three sizes (SM, ML, and LXL).

Trail Boss of Stoke

Erin Trail’s hobby is collecting hobbies. She’s a 5th Generation Coloradan and grew up exploring the outdoors on family camping trips and hikes. Her first backpacking trip was at eight years old to Grizzly Reservoir – she proudly carried all of her own gear those 3 miles from the main parking lot to the Reservoir.

Erin is an adult-onset athlete who started as a Masters Swimmer and then developed into a triathlete. She has completed 5 Ironman races and nearly 20 x 70.3 distance Ironman races, including the World Championship in Lahti, Finland, in 2023. In 2025, she raced for Team USA in Pontevedra, Spain for the World Triathlon Cross Tri World Championship. She placed 9th in her age group and was the 1st American woman in her age group.

Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it. She’s got all the bikes: gravel, mountain, fat bike, time trial and road.

She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering. She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).

Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).

In 2026 Erin took the National Championship in her Age Group for the USA Triathlon Cross Tri. She’s also racing the a National Championship Road Sprint and Olympic Distance race in Milwaukee and a few other off road triathlons and bike races. In 2027, she will represent Team USA at the World Championship Cross Triathlon in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.

When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
