Excellent Backpack
I have more than one of these. I like this new model more than the previous mainly because this includes a second water bottle pocket. I’ve used these bags for many things. Most recently, it has become my backpack for biking on the trails. It’s light, water resistant and comfortable. I’ve maybe carried up to 20 pounds in it and it still looks new.This is a great bag and has been very durable. The shoulder straps balance the load well. There isn’t any structure to its “frame,” but that doesn’t deter from its comfort – you can always put something in it, included a foam pad, but I never had needed to). It looks like the day I got it…and it’s going through some rain, heat, sweat and being tossed around. The seams are taped and provide some water resistance (the Osprey Dry Sack is someone more water resistant as it has a folding top, similar to a true dry bag).It packs down relatively small, but unless you’re carrying something else (jacket, purse, large cargo pockets, luggage), I wouldn’t say this is “packable on your person”.I highly recommend if you like lightweight stuff. It also comes with a lifetime warranty if something does happen to it…which I don’t see happening anytime soon.

Excellent day pack
This is a great pack for going around in the city.I especially enjoy it when traveling. Even though it’s pretty small and compact, it can carry a couple of water bottles, a windbreaker, snacks and other stuff like that.

Nice light weight packable bag
Awesome bag. Super light weight, very thin but pretty durable for what it is. The straps are comfortable and it can hold a good amount as well, was able to bring two full sized towels out to go swimming while on vacation. The orange color is very but I like it. It also folds up surprisingly easily which is great.

Highly recommend!
This backpack is durable and versatile. My husband and I used this for our 2 week trip in Europe – it held waters, snacks, portable chargers, and a jacket with extra room to spare. It is waterproof and withstood a few rain showers. We were able to roll it up and pack it into a suitcase when we were traveling. The zippers are durable and kept our belongings dry and protected. We now use it for day trips and hikes. Highly recommend!

Nice no frills lightweight/could use some tweaks/is not very water repellant/45 is kinda high
This backpack is wonderfully light and durable. I love the top pocket for stashing items you want to get to quickly. I have taken it hiking and also used it as a personal item carryon. It holds a lot! It’s very packable. Zippers seem sturdy. Straps are adequately padded for day hiking. I would give it 5 stars but for a few drawbacks. The features and specs say the item is water repellant. It started raining while I was hiking and everything in my bag got drenched. Not sure how it would hold up in light rain, but in a downpour, it did nothing to keep my items dry. The bag features a sternum strap. Would love for them to add a hip strap! I feel like $45 is a bit high for this bag, but would be well worth it if the bag were waterproof and had a hip strap.

Great pack, light and collapses well
This worked great for me as a say pack traveling in cities. It’s super basic, so maybe not for everyone, but being super light is a huge advantage. I travel with a bigger pack, but this thing is so tiny it’s worth it’s space in the suitcase if you’re walking around all day and don’t want to carry a full-fledged backpack.

Great for travel!!
Great price. Moderately waterproof (rain). Straps provide decent comfort/padding. Immensely good for travel. Large capacity for a day hike. Top, zippered pocket is great. Chest strap is paramount! Well designed and constructed: I expected nothing less from Osprey.

Must have EDC
These bags are great. Light weight and easy to travel out be mobile with. We lost one and had to replace it, but it’s so good to have!Haven’t had any issues with quality, it’s lasted well.

This pack is a perfect complement to my larger travel pack and fits easily inside it when I’m travelling. I’ve used it several times on extremely hot days on full-day hikes. I’m not sure if sharper objects would tear the pack, but I’m not going to tempt fate!

Niestety plecak jest beznadziejny. Dokladnie chodzi o jego skladanie. Pech chcial ze mialem poprzednia wersje (bardziej pomarańczowa + grafit, tylko z jedna niezamykana kieszenia boczna) i niestety ją zgubilem. Lubilem ten plecak i stwierdzilem ze zainwestuje kwote 2x wiekszą w tą wersje (poprzednie nie do dostania). Wszystko bylo fajnie, az do momentu skladania. Ktos kto to wymyslił powinien zmienic prace, naprawde. Poprzedniego bylem w stanie ladnie zlozyc w pare sekund, tego nawet w minute nie mozna nawet jak chce sie go zlożyc byle jak, “w kulkę”. No tragedia… Sam plecak ok – 2 boczne kieszenie, gorna osobna ma w sobie jeszcze mala zamykna na rzep, paski ok (ale juz paski piersiowe bez sensu, bo ruchome). Generalnie jestem zawiedziony i nie wiem, po co ktos to zmienial…

丁度いいサブザック、やっと見つけました。しっかり目のショルダーハーネスにチェストストラップ、それなりの荷重に耐える設計。1気室+サブポケットのみ。非防水、ウエストベルトなし、背面パッドなし、ボトム生地補強もピッケルホルダーもデイジーチェーンもトップリッドも一切無し。サブザックに割り切った設計で実測145gです。涸沢からの奥穂、剱沢からの剱岳などサブザックが活躍する場面は多いですが、立派な背面パッドで畳めなかったり、今にも破れそうな大陸製品とかばかりで、「ちょうどいい」のが本当に少ないです。これで長年の悩みが解決しました。色がダサくてもどうでもいいです。
