This pack is a perfect travel item. It folds down to a ridiculously tiny size; weighs virtually nothing; is strong enough to hold camera equipment and it’s comfortable to wear all day. The color was nice too. My sister keeps hers handy in her car when not traveling out of the country. It’s great value for the money. Very versatile.

Love this compact backpack! Had it 4+ years! I usually leave it in my car and take it when I need it. Sometimes I use it when getting just a few items at the grocery store. Other times if I go to fairs, other stores, or any event I may pick some items up at. I just put it in my pocket, or, clip it to my belt loop. I don't even notice I am carrying it; but, if I do purchase something it sure is nice to have! I recently took it on a vacation and it came in handy bringing drinks and snacks to the beach; and also, holding anything purchased. I've had my first pack for over 4 years and it still is like new. Sure maybe some scuffs, but, no actual damage. It has shed away light rain. But, heavy rain for extended times will get inside. I am going on a cruise with my fiance, her daughter, and her daughters friend soon. I decided to buy another one of these! We will be in the Bahamas, so, I figured having an extra may come in handy for someone else to use if needed. You can be sure I'll be taking both back home at the end of the trip though! These bags are awesome! I wouldn't use it as a daypack or for backpacking; but, for the uses I wanted it to perform, it is outstanding! If you want the smallest and lightest bag to have with you in case you need extra carry space, get this bag now!

Needed a packable bag that could fit in a fanny pack / sling bag for an upcoming trip. Pro: Incredibly small, really fits in the palm of your hand. Zipper quality seemed solid, I imagine full it could be light and easy to carry. Cons: Overpriced for what this is. Also, the gray color was too transparent - everyone will see what you have in your backpack. I ended up returning this due to similar options being available from Amazon. I ended up going with a "4Monster" 24L packable bag, that while it doesn't pack quite as small - does offer more features.

I absolutely love this backpack as a super lightweight day pack when I travel. It weighs nothing takes up no space in my travel backpack and holds everything I need for the day while saving my back from being in pain (I have a bad back and this is great). Will it fall apart on you? Yes ... Eventually. BUT I was able to use this bag across 4 continents carrying my water bottle wet swim suits first aid kit and sunscreen I needed. Was able to keep the straps on with safety pins which worked great because the bag it's self is so light. This was possibly the best value for money I have ever purchased for traveling because it saved my back from pain while carrying everything I needed for an awesome day. And I was able to nurse it along for so long. I eventually got rid of my first back pack (a very sad parting) but I bought 2 more one I'm using now and a spare for when this one also gives up the ghost. Bottom line yes it will fall apart but until then it's great!

Purchased few months ago and used this bag just one time on a short trek, had it packed with some light clothes...bag tears very easily and material is not strong at all. Had multiple small tears in bag after just one use. Bag was very compact & light. Wrote manufacturer because they claim to have "lifetime warranty" had me send pictures and receipts just to tell me they won't cover it and I should buy some tape and repair it myself. Plenty of better quality and lower priced bags in the market.

I travel a lot for work, and on the rare occasion I have some time off I like to explore. The ultra sil pack is incredibly compact, but it’s ruggedly constructed and easy to deploy and stow. It can carry an adequate amount of gear, but I feel like it shines as an impromptu shopping bag for souvenirs. If you’re a regularly traveler this is a no brainer.

I bought this to use on a few day hikes while on a much longer trip. In the end I could not use the pack for that as it slid off my shoulders so badly I was constantly having to hold it on or adjust it. Might only be an issue for someone of my build. It is very compact and light so it if would work for you I would recommend it. I may sew on a chest strap to make it work.

Small, lightweight, yet spacious when open for use. I highly recommend as a day pack or carryon bag. I used it as an insert for my backpack, and kept all of my clothes in one space.

軽量で丈夫、生地ウルトラシルがパラシュートおよびヨットのセール(帆)用で非常に強い。 ロードバイクで遠方の有名パン屋とかに立ち寄ってもこれを折りたたんで持参しておけば、担いで持ち帰ることが出来ます。裏替えして内側に縫い付けてある小型の巾着袋に丸めて収納、圧縮すればとても小さくなりサドルバック等の奥に入れても良いし。自転車用ジャージの背中のポケットに余裕で入る大きさです。

Had to make special mention of lightning speed shipping- especially with current delays. Excellent product!

Il web ormai pullula di oggetti EDC (Everyday Carry) che poi nella realtà non si portano con se veramente tutti i giorni. In questo caso l'acronimo EDC è quantomai azzeccato. Lo porto con me quasi sempre, nello scooter, in macchina, attaccato allo zaino, o al passante dei pantaloni, o in una tasca. Lo uso per una spesa non programmata, per raccattare plastica e lattine nei boschi, o castagne o altri frutti nelle mie camminate in natura, esca e rametti per fare il fuoco. Insomma mai lasciarlo a casa. Lo zainetto è inaspettatamente robusto in relazione al suo peso. La cerniera è robusta e non sembra affatto un punto debole, come evidenziato dalle recensioni della versione Ultra-Sil Nano, certamente più leggero ma anche più delicato. E' anche comodo, anche se serve un minimo di peso per stabilizzare gli spallacci che non hanno la chiusura sternale e sono del medesimo tessuto scivoloso (per il trattamento DWR al silicone) del sacco. Il materiale è idrorepellente allo stesso livello del mio poncho Sea To Summit, testato anche nelle tormente. Nonostante ciò, non penso tenga l'acqua fuori quando piove forte, perché le cuciture non sono nastrate. Una scelta comprensibile perché l'alto livello di stropicciamento necessario allo stoccaggio rovinerebbe certamente le nastrature col tempo. Anche la cerniera non è stagna. Una cerniera stagna sarebbe stata incompatibile con l'esigenza di stipare lo zainetto in un sacchetto che sta nel pugno di una mano. Naturalmente è logico aspettarsi la schiena sudata in estate dopo un certo tempo di utilizzo. Non era certo possibile inserire qualcosa di traspirante nella zona a contatto con la schiena in uno zainetto che fa della sua forza la estrema trasportabilità quando non è utilizzato. E' dotato di un piccolo moschettone, leggero e di qualità decente, che si può convenientemente spostare sull'anellino superiore quando si apre lo zaino, così da poterlo appendere se serve (ad esempio al gancio portaborse dello scooter).
