Field Functionality & Design Features 

We tested the Fastpack 20L, on the Big Island of Hawaii, while competing in the self-supported, 6.5 day, 250km Mauna to Mauna Ultra-marathon.

If you’ve never run this type of endurance race, it’s sort of like ‘aggressive backpacking’ with cut-off times, stages and checkpoints. Competitors have to carry all their own food and gear and camp along the way. Ideally, you want your backpack and all its contents to weigh less than 20lbs.

 
We picked the Fastpack 20L because it is light weight, has front water bottle pockets for easy access and the size would force us not to pack too much. We learned this was a good thing and a bad thing.

Everything we needed fit into the pack (sleeping bag, pad, food, extra clothes etc.) and it weighted just over 20lbs. We loved the side straps for compression and all the pockets. That being said, the weight put a strain on the pack's comfort level.

Without a hip-belt, to help distribute the pack’s weight, our shoulders and back were sore at the end of each day. In addition, because we were running, to keep the bag from bouncing, we had to tightened the chest straps. This restricted breathing. Ultimate Direction does not make a pack under 30L with a hip-belt.

Don’t get us wrong, we still enjoyed the pack and did well in the race, but would recommend, when relying on only two chest straps, keeping the pack’s weight under 15 lbs. For self-supported races and long distance adventures, try going up a pack size and if at all possible, use one with a hip-belt. *

* Ultimate Directions' new Fastpack 35L and 45L have hip-belts.
