WATERFLYLightweight Packable Hiking Backpack: 30L Foldable Travel Daypack Ultralight Camping Day Pack for Woman Man

I bought this pack because I want to get further into ultralight hiking as well as travel but not spend a fortune. I bounced back and forth between the 40 and the 50 liter. I ended up going with the 40 because of all the research I did. I figured (in the ultralight mindset) it was better to not have too big of a pack. Im a 5'5 male and this pack is a perfect size for traveling ( I wouldnt go any bigger, and I could stand to loose 5 or so liters, just for traveling) But it is great quality, light weight, straps are nice, buckles are good, zippers are good, whistle sucks :) but still cool. One thing to note if you are getting it for ultralight hiking. the 40 liter is going to be tight (I was able to stuff 3 crumpled up large bath towels in the main compartment), I was worried about getting the 50 because of how high it would go over my head. This one is right at neck level and doesnt go down too far over your back. You could only do 2-3 day hike. if your sleep system is a hammock it is PERFECT, if it is a bivy tent and sleeping pad its going to be tight i might go with the 50 (unless you strap it on the outside). The only problem is the main compartment seems small because the suspension system and part that keeps bag directly off back and allows airflow seems to constrict it a bit. I have looked at all the osprey,REO, and gregory bags. This bag is just as nice as them. not sure how the waterproffenss is going to be. Overall I would go with the 40 over the 50 and make it work. Remember if you buy a larger pack you are much more likely to fill it. if you have to cut out some things thats what makes it interesting and challanging. One last thing I read on one of these reviews that the hydration tube port was not there or was sewn shut. Mine was perfect and there is a clip for the mouthpiece on the shoulder strap. Lots of teather points and there are places to cinch the pack as tight as you want. I really like the waste strap with the small pockets that will be good for quick reach items like phone,gps, passport, wallet, snack. Last thing, they put the small pocket for the rain cover in the base of the bag. I really like that because you can reach back while pack is on and get it out then sling off the pack and have your cover ready to put on quickly. overall well thought out pack and good quality for the money.

Top quality. This is my second one. Very packable and holds so much. Straps are very durable. Just a really nice product.

This is a nice lightweight pack, holds a fair amount, two large metal 40oz water bottles, and books along with other items. Doesn’t ride perfectly on the back but isn’t uncomfortable either. The straps can be a small pain because they are flimsy without any mass or side supports, but once you get them untwisted they work fine. The chest strap is fair for some help shifting the load partially off back and shoulders. For the price it’s a good little day pack.

Nice quality and function. Appears to be a durable easily packable lightweight backpack.

Perfect size for us to take on walks and hikes to carry our water bottles and anything else you need to have with you.Great to take with you when you travel.

I purchased this for a trip to Alaska. It was lightweight and perfect for travel. Lots of pockets to keep organized, comfortable and adjustable straps, and water resistant for the light rain we experienced. We didn't have heavy rains to test just how much water it would resist. I highly recommend!

I needed something for carrying stuff off of the cruise ship but I didn’t want to use it as my personal bag on the plane. It fold ups small but it hold a lot when unfolded.

I travel so I thought this would be great to replace my travel backpack and have "portable, foldable" bag. When I shop in another country, I go light in case I don't buy anything but want a bag for the finds! But I'd prefer to keep in it a jacked pocket until I need it, this is much too big for that.What I liked:- Lightweight- Holds a lot- Great compartments including hidden, water and a front area- Folds up- Waterproof pocket- Padded Shoulders don't dig- Fatigue strapping on chest & waist- Good option to throw in your luggage in case you buy too muchWhat I did not like:- Folds up big and bulky, I need a bag to hold this bag!- Does not fold up easily, no instructions- Not waterproofSUMMARY:It's hard to know what to rate this. Do I rate packable & lightweight? Or design. I'm in the middle. It's a well made lightweight bag but it's NOT super portable (put it in a jacket, clip on jeans) - which is why I bought this bag
