This is a very functional tool that has a great product design and manufacturing quality at a great price point.
Anyone who has a need for extra light outdoor or indoor will appreciate this light. Once you try it, you ask yourself, how you live all these years without a headlamp. Whether, you are doing under the sink plumbing work or walking or jogging on the trails or fixing a tire in the dark. This light is so light and compact, you can take it with you without hardly noticing it's there. Burn time is rated at 100-150 continuous hours which is unreal.
The draw cord pod is a very versatile in design which you can slide over smaller diameter such your arm or a water bottle to use as a makeshift lantern which you can adjust the light directions in many ways.
If you are a fast night trail runner, try their brighter light. This is not really designed for that. This light is for doing tasks in the dark and jogging rather than full speed trail running. I have tested this light in the pitch dark trail running and it is definitely doable.
Finally, don't let the size fool you on the brightness. You'll be pleasantly surprised how bright this little thing shines.
Unless you can see in the dark, I recommend this light to anyone. Since the band is a thin string rather than a band, it is almost invisible and it's low-key so it is good to use around the house and your neighbor doesn't think you are a weirdo.

The garment is soft. The inside has almost a cashmere-like feel. The mesh fabric is breathable and flexible which allows free movement. The shirt fits almost like a comfortable sweater, but it is a sweat-wicking fabric and keeps you cool. As a mid layer it is also an insulating piece. The pocket is stitch-less patched pocket so that the inside does not scratch you when you wear this as a base layer. I hope the patch pocket does not come off after years of wearing because this shirt is a keeper. Tip: cold wash and hang dry will maximize life.
