He explained he can hardly feel the helmet on his head. He was glad it does not make his neck tired. He has the medium/large size because his head is a bit big.

2. Troy Lee Designs Stage Full Face Mtb Helmet [Best MIPS Overall]
The Troy Lee Designs Stage is the best full face mountain bike with MIPS. MIPS helps to protect your brain from serious injury and may save your life. During a mountain biking crash because you are moving forward the crash and your body will have increased rotational motion.
This type of motion especially can cause brain injuries. With the MIPS system a low-friction layer glides 10 to 15mm in all directions. During impact the rotational motion is reduced which decreases impact on the head and brain.
The first rider explained to me that he was very happy that this helmet is very lightweight and incredibly durable. This rider has not been in any crashes with this helmet but feels like this one offers more protection compared to the other helmets he has worn. The helmet is quite breathable as he wears it and very light.
The next rider rides singletrack in Arizona year round. He described the air flow and cooling of his head as amazing. When he has the helmet on it feels like very light. He uses the extra large size because of his head size. The only negative is he still needs to get used to the clasp.
The third mountain biker goes riding on weekends. Each ride is at least 20 miles. He says other riders think a full face helmet is too much but this Troy Lee Design helmet feels like it is not on his head. He rides in Nevada which has 90 degree heat. He sweats less in the Stage than the Giro. The ventilation and airflow is exceptional.

The first rider explained that this helmet is very good for the price. This is why I chose the Demon Podium as the best budget. Many other riders said the same thing. He usually wears a size medium but this size felt tight with this helmet so he exchanged it for a large. But then the large felt loose. So he fixed that by adding replacement cheek pads. Now it fits perfectly. He finds that the included goggles are breathable and very clear.
The next rider found this helmet to be comfortable. He did get into a crash, but fortunately he was wearing this helmet and it gave him good protection. He came away from the crash just fine other than scratches on the helmet. The only negative is the helmet scratches easily and sometimes it can get hot.

This helmet is made of carbon which makes it very light. It also has a race ready fiberglass shell that is light weight as well. It will protect you against very severe impacts from downhill trails.

The MIPS dial does not dig into his spine at any angle which is great because he had this problem with other helmets. The 3R does not heat up as much as the Switchblade. He thinks the 3R is very cool with good air flow.
The Bell Super 3R because it is pretty light keeps you cool but it also has an Overbrow Ventilation system. This system includes intake ports on the brow of the helmet to bring in cool air and push it though its air-channel network for ventilating the entire head.
