The Good: Light, looks good, ventilates well, doesn't interfere with a backpack.
The Bad: Half-foam mouthpiece, doesn't look like it'd hold up in a really gnarly face-first crash.
First off, I bought this helmet because I wanted a lightweight, breathable full-face that I could use as my one and only helmet. I ride mostly all-mountain and technical trails, but also do some dirt jumping and full-on downhill. After a couple months of use, I have had no issues with the helmet.
Climbing - Though it is still a full face, the Urge breathes relatively well and it's light weight is noticeable. It allows a decent amount of peripheral vision, and the highly adjustable visor can be slid up so that it doesn't limit vision.
Impact - I've only crashed a few times with this helmet, but so far it has held up nicely. The flexible visor is plenty strong, and didn't snap even though I once landed directly on it. My one worry is with the half-foam mouthpiece, it doesn't seem like it would be able to handle a full-bore, face first crash. But of course, what is gained in breathability is lost in protection.
Overall, the Archi-Enduro is a great helmet for a trail rider that is insecure with a open-face helmet, and doesn't mind giving up some breathability. Though I wouldn't suggest it for regular downhill or freeride, the Urge is a versatile helmet that will benefit the shredding enduro rider.
