Cons: short run time, not fully waterproof, small buttons on and off.
Flashlight BioLite 330 has the thinnest profile of all included in the rating. The lamp located on the front almost merges with the belt, and the thin battery pack located on the back perfectly balances the system. BioLite does not bounce or slide when moving, making it a great choice for nightly jogging and hiking. In addition, the very fact of moving the battery pack back makes the design of the headlamp more comfortable and balanced. The advantages of the BioLite 330 model are good brightness, the presence of a rechargeable battery and a battery status indicator, which means that before you leave home, you can always check how much charge is left. On the practical side, BioLite is an excellent choice for both jogging and walking, and for multi-day trips that do not include night transitions.
