I don't bring a lot of gear with me but I do bring multiple lights. I have never had one fail on me, and the lights that I bring are all durable high grade / high quality lights but I just like lights enough that I am willing to carry the extra weight.
When I backpack, I typically go w/my wife and we share some of the common gear. Here is what I typically carry:
- Tent
- 2 Liter pot
- Stove
- Fuel for stove
- Lighter
- Compass
- Water filter
- Food
- (4) Nalgene (1) liter bottles (I don't always fill them all)
- Sleeping bag
- Sleeping pad
- (2) changes of clothes (1 for hiking and 1 for sleeping / camp)
- Marmot Precip jacket no pants
- (1) Small MSR PackTowel
- Headlamp
- Flashlights
- Knife w/multitool
- Medical kit
- (2) Trekking poles
- (1) Pr. Teva Sandles
I carry this in my Osprey Aether 70 backpack and it maxes it out. I would guess that my load w/food and water is around 40 to 45 lbs. The flashlights and the big knife (Strider Sniper or Busse Steelheart SE) make a difference as does the multitool, but I am o.k. w/that.
I should be going out again at the end of this month for a 4 day hike w/my boys and maybe the wife. My choices for flashlights will be tough, but I plan on bringing on of my HDS Twisty's (when it arrives; I don't know which I will prefer) and my Black Novatac and leaving my headlamp at home (I plan on putting the Novatac in a NiteIze headband instead).
I don't know of a light better suited for backpacking than the new Ra / HDS Twisty.
