Running

Some more about Petzl Bindi vs. Nitecore UL25 as I have this on my desktop right now and thought some in the market for a good entry-level headlamp may find this useful -

Like I said I really liked the Bindi, for it's simplicity mostly, and it's nice design. Also heard a lot of good things about Petzl in general.

..note this is the old version though, which got replaced by the new UL25 (also sometimes called NU25-400) and the "ultralight" version NU25 UL.
I chose the old one as I liked the design more and also the features were more ideal for me.
Liked the idea of that double-cord-band of the UL though (like the Bindi, but probably better, I thought) so I did my own with black 3mm bungee cord, and put a little blinking light in the back (just bodged it together with sliding knots to try it out, might just leave it like that though - it's 51g total, and fits very comfortably, I literally forgot it's there after two minutes 💁🏼

My primary reason for getting a headlamp in the first place was being able to see the ground better / being able to run in parks that have no lights whatsoever - and I disliked the sketchy feeling in the dark (fear of falling or rolling my ankle because I didn't see that stick etc.).
I quickly noticed how running in the dark (with a headlamp, in your little light "blob") is also super cool for meditative running, for really focusing on your movement and breath (with these temperatures right now you do actually see yourself exhaling into the bright light every time, very dramatic : ) -
so I suppose this is a big selling point if you're into that type of running and are thinking about whether to get a lamp, it's really cool as you can't have that like that during the daytime / with all the visual stimulation and people around etc..
