This is all helped by the dual straps on the back that help to keep it fitted to your head (instead of a simple single strap that many other head torches have).

Petzl SWIFT RL - One Headtorch to Rule Them All? REVIEW: Petzl SWIFT RL - One Headtorch to Rule Them All?

The Swift RL is home to a Lithium-Ion 2350 mAh battery, something that can be recharged via the type B micro USB port. The double “split” band at the back provides a much better system for keeping the head torch in place.If you thought that was all that could be said about straps you're wrong, because there is one final feature: it's reflective too (great for spotting your climbing partner, or for visibility whilst running on roads).

Petzl Swift RL head torch review: a bewilderingly bright - T3

I think I just find it more customisable and less faff to get the beam profile that you want without having to use a phone app. In truth, and from what I have discovered when discussing the reactive technology with others, I think the reactive beam is far better for solo running or when you are walking.Then for round campsite you can just have a low light flood by pressing a button rather than having to select a campsite profile on your phone. Charging is via a micro-USB port and takes about six hours claimed, which seems about right (this is based on a 100% charge – Petzl claim that it charges far quicker to 80%).
