Comfortable and sturdy
While it is very thin and transparent, it’s remarkable how such a small pack size backpack can be so comfortable and sturdy. This has replaced my tote bag in my handbag and in my travel bag.

Superb
Great product! Strong, light packs down to nothing. Worth the money.

Poor quality
Very thin, almost see through. Very difficult to pack it back once unfolded. Not worth the price. Bear in mind that this is a third party company, they advertise a free returns option, but that’s not the case. Very misleading, avoid them!

Very very thin.
Very small but the material is very thin almost transparent. Not sure how comfortable I would feel with anything of any value in there, particularly while wandering around cities. Other than that it's extremely light and packs down very small.

See through. You’d have to be kinda desperate …
It feels like the backpack equivalent of those raincoats that scrunch up into a tiny balls. I’m sure it does what it says but I didn’t much like it. If you’re stuck for a very see through backpack to squeeze into a corner of your luggage go for it but …. I haven’t used it and don’t plan to.

こんなに小さくでき、約15リットル入るデイパックはこれぐらいだと思います。 ブラックダイヤモンドのシラスはこれより軽く小さいみたいですが、あまり見かけなく値段も高いし容量も小さい。 よく中華製の同じ様な物もあるが、まず縫製がこちらのが頑丈に出来てます。 何回も使ってますが、縫ってる所がほつれて穴が空いた等は無いです。 中華製のはよく肩の付け根付近から破れてきます。 ファスナーはYKKの印字が無いので、YKKじゃないかもしれません。 生地が薄いので、あまり見られたく無い物等はポーチ等に入れた方が良いかもしれません。 収納時の小ささ、軽さ、背負い心地は最高です。 何かのバックに入れたり、カラナビでベルトループに付けたりと、何処にでも持って行けます。 軽さは七難隠す。 とは言いませんが、それぐらい軽さは重要だと思います。 お金に余裕があり、出来るだけ小さく収納でき、軽く、そこそこの容量のデイパックが欲しいなら、 これ一択です。

This bag is truely the smallest bag i have seen! It is smaller than even the shopping reusable totes you can buy. The bag itself is very thin and plastic like, but for travel, and for an emergency extra bag, it is great! It can be a tiny bit hard to stuff back into it's little pouch, mainly because the material is so slippery, but once you get used to it, it's not too bad!
