I bought the Swift II after several years of having the Lumbar fanny
pack. The present Vibe II, is the one most like the small pack I have.
For walking around the neighborhood the small one suits me just fine,
however sometimes I want to carry more than what can fit in that, so I
bought the Swift II. For instance this week I went to an exercise
class and put two two pound weights and a fitness tube, a stretch tube,
in the Swift II. This is the maximum I would want to carry in this
pack. I like the design of the weight resting on my hips.
There are a few details I would like to see improved. The pack needs
some protective grommets on the bottom, it has a flat cloth bottom.
It looks like, if you were too casual about resting it on ground, it could
wear out quickly. The eyewear pocket can only accomodate a small
frame. I have shown that in my photo.
