Perfect gym/swim bag. Lightweight and roomy.
This pack is a game changer for me. I’m 75, 3joint replacement and a spinal fusion in the last 15 months. I still use a cane and swim 5x a week. I got tired of schlepping a regular gym bag–too heavy and cumbersome, so I bought this, along with their microfiber bath towel. Everything from my old bag fits easily in this. The towel is amazing, compact, lightweight, and comes in this nifty case that I use for goggles, nose clips and earplugs. And my bag now weighs a third of what it did and a pack is much easier for me to carry. Can’t recommend this highly enough.

Lightweight and packable, not super durable
I bought 3 of these for my family to use as pack able daypacks on a 14 day trip to Peru. They got lots of use, and were suitable for the purpose. They pack down super small and take up very little space in your luggage, but unpack large enough to fit a layer or two, a water bottle, and whatever you need for a day trip. They are very affordable and everyone got through the trip successfully. No one treated them super harshly but they ended up with the some tears in the fabric. Buy this for a trip or two, or occasional use and you won’t be disappointed. If you want something for more frequent use, heavier use, or want it to last a long time, spend the money on one of the big brands.

Love love love this bag as a Race drop bag!
Absolutely LOVED this lightweight pack for using as a drop bag during a multi day staged ultra race. I was able to wear my puffy jacket before the race then stuff it in the bag along with a pair of flip flops (though if doing a drop bag for a regular ultra you could fit a pair of running shoes in them), a camp towel, a Nalgene with recovery drink, and a few other small odds and ends. It did not bog down with weight. The color is a beautiful blue-green and through six very rough days of transport held up well without any tearing, holes, or visible wear. I would say it could handle a light drizzle but nothing substantial as it isn’t taped seams or heavy fabric. I was able to wear it as a backpack easily over several layers. When finished it scrunched down super small into your hand. Love that it had a few extra pockets to store things instead of one large opening. I HIGHY recommend this bag and if doing a large ultra I would definitely get several of them in different colors to define what each has in it. I would NOT recommend this as a regular hiking bag- it doesn’t have the support you would need to carry items long distances. I would recommend a proper hiking bag for that. As a drop bag or lightweight carry bag though its golden.

Perfect – LIGHT strong capacious, nothing cheap
Extremely impressed. Just got back from another (probably the 5th) moment of “let’s go on a hike, oh shoot I don’t have any backpack, oh wait – I have that mini one in my car bag!”It’s strong, SO LIGHT, very very well set up – pull and zippers and pockets all in a good place. The zippers are great. I used it in the rain again, it gets wet eventually, but sheds water well and my Bible on the outside pocket was perfectly dry. You CAN STUFF this thing, it holds a lot! I have the large and medium I beleive, both are perfect. I have never run out of room. I’ve run demos for the wife showing how much I can keep putting in there!It’s very comfortable for having no comfort features. Unbelievably light.I HAVE fried other mini backpacks. They were also impressive, 2 other ones (sorry, I don’t remember them now – but that means I’ve tried this for over a year on multiple occasions) – but bulkier by far. This is JUST RIGHT. It is one of my possessions I LOVE. totally worth it if you can swing it. I didn’t buy it for 2 months because of the higher price, but in the end it has brought me only delight. No tears, wearing out, stretching, no marking of the sipper rubber, the pulls are still perfect. And it packs up so tiny. People don’t belive it. I can put two full sized Nalgene bottles on the sides, lots of snacks, way more knives than you’re thinking of, books, and clothes in there. It just keeps stuffing. And I don’t feel sore or fatigued in a way I’d expect – it sits right on my shoulders and distributes nicely. What can you expect from a bag that weighs less than a padded shoulder strap? We’ll you get it and more. We’ll done guys. Really nailed it, didn’t cut corners, doesn’t feel cheap in anyway. Very impressed. Holds a lot of weight.I don’t love how easily things poke through to my back, but put a peice of cloth in there and it’s fine. Very very thin material.

MUST HAVE
Traveled throughout Asia with these, got in two colors, we love them, light and effective. Essential for light day packs in subways, comfy to wear on front or on your back.

Great Product
I love this product. My use case is when I hike/backpack, I set up a “base camp” where I stay for a few nights. From there I do a few day hikes – and I use this bag for those. It packs into my main backpack with very little space. It has almost no weight, but it has held up perfectly. It’s surprisingly durable. Sometimes I pack it quite full and it has never failed me. The shoulder straps are comfortable enough without having a bunch of padding – which would take up too much space for me.
