Its main claim to fame is probably its use of Dyneema for the body fabric – it is one of the only (if not the only) DCF bag on the market in this form factor. Beyond that, the bag is also notable for its beautiful minimalist design, subtle details and choice of high tech materials such as YKK aquaguard zips. Conversely, its main weakness is probably its rather high price tag of approximately 48,000 JPY+tax/shipping. (Note: I accidentally wrote 45,000 JPY in the initial card of the video)

Nonetheless, for fans of Dyneema, minimalist travelers with tightly dialed kits, and adherents of the philosophy that bags should be simple, lighter and less fussy than the contents they are carrying, this bag is a wonderful option worth considering if your budget allows.

    Please note – this bag currently retails for 48,000 JPY, not 45,000 JPY as I accidentally wrote in the title card. I regret the error.

    Hey Mountain,

    New account, long-time viewer. I’d like to offer some input on this bag from an outdoors person’s perspective and it starts with a history lesson. Dyneema Composite Fabrics (DCF) were originally developed for the sailing industry for mainsails and jibs. This is an ideal fabric for this application because it has very (very) high tensile strength (pulling force) and does not absorb water (a good quality for something which may become submerged). This fabric found its way into the backpacking industry where anything and everything from backpacks to organizer bags to tents are made from this material.

    Sounds great, right? Well, not exactly. DCF fabrics do not age gracefully. Because they were designed to be pulled taught all the time, they do not have good recoil/memory. Over time this results in the bag developing crinkles and folds and actually ‘skrinking’. Many consider this very aesthetically unappealing. DCF tent manufacturers actually suggest folding the tent the same way all the time to avoid this. However, in areas of repeat folding along the same lines those folds develop into cracks and holes (less than ideal for those seeking a waterproof bag). Now, if you have $500 to spend on a bag perhaps this isn’t a financial concern for you. If however you’re looking for an investment piece, DCF has a very predictable course of break-down and people considering this bag may want to look elsewhere. For more information, checkout Darwin On The Trail’s video (skip to 6min45sec) —

    Personally, I think DCF is an overused, overhyped material. A 2, 2.5, or 3-layer waterproof-breathable fabric like GoreTex or a 3-layer waterproof material like XPac is made with a nylon face fabric which will look almost identical throughout it’s entire lifecycle and would provide the same waterproof quality as DCF without the risk of ‘splitting’ and developing holes.

    The capacity to weight/vol ratio of a bag is an interesting point. My personal gripe is bags that have super over-built dedicated laptop sleeves. Like if you're traveling around the world in 35 litres, are you really going to be bringing a 18 inch, thickass laptop? Not at all. But the extra space bringing a 13" slim laptop isn't useable at all, it's just dead padding. And ignoring the fact you're going to be carrying soft padding (clothes) as well – the pact bags solve this problem pretty cleverly. Same with bags which have excessive material weight, like do you really need ballistic grade material if you're not getting shot at. What's the chance a bag is actually going to break due to abrasion on the fabric, compared to zipper dying, shit getting split in it, theft etc.
