Super lightweight! Great for backpacking. One size fits most, the waist strap is very adjustable. And I love the color!!!

  • awesome!
Color: Army Green-2 Size: 2L
So compactable. Roomy, great color, good nylon. I took this hiking. I would recommend getting a carabeener to clip it to a bag.

  • So very light and waterproof, amazing!
Color: Navy Blue Size: 2L
Love this brand so much!!! This fanny pack is perfect to sit Over/under my main 70L Deuter hiking pack, comes with a tiny stuff sac that stays inside the fanny pack when in use. Exactly the size of 1 pack of cigarettes is how small it packs down to. Cuz that is all that will fit into the tiny stuff sac. Even the zippers are sealed properly. Just large enough for my meds, a pack of gum, doobies, extra smokes and 1 snack; The things that I access constantly while on a hike. Took about 1lb exactly out of my pack and off my back, can't even feel it on me when my my pack on too. I clip this fanny pack on first then the main pack over the strap in the back and the main pack clips under the fanny pack in the front. It's perfect!! I ordered this brand of fast dry camp towel (almost like a chamois), it was a little small (was my fault, chose wrong size) and I ordered a sea to summit In the next size up, their exactly the same right down to the vented case the come in. Exact same quality and seam stitching, tags everything. And the 4 monster is definitely lower priced than anything sea to summit, I highly recommend this brand, from a serious hiker. Will see this used on my youtube: Megan S. Hiking with a Purpose. I washed my hair in the chagrin falls river on my thru-hike attempt, used it to dry my hair.. and it really did dry my hair and then the towel was dry almost completely with just 6 hard snaps to shake the water out!!! Also used it at a camp ground, and used the wall mounted blowdryer to dry the towel, was completely dry in just minutes. ... show more

  • Material is like a wind breaker.
Color: Blue Size: 2L
Love this fanny pack! I’ve been looking for a good one to use for traveling. This one is nice because the material is super light and malleable, which is great when you want to wear it under your clothes instead of over. So the downside of it being too light it not anti-theft actually makes it its strongsuit if you just put an oversized top or jacket over it because it’s not even noticeable when you hide it. The heavy-duty options out there are typically too bulky for me, and the shape is sturdy to the point it’s too chunky to hide under clothes, this one is great for doing just that! When completely filled it can hold a lot, so it’s really up to you how you pack it. I like the loops on the side, I have often hung a carabiner from it to hold my water bottle at times when I don’t want to hold the bottle. There a nifty key holder so you don’t lose your keys, and the same pocket has the built-in bag you can squish this pack into when not in use. I don’t really like the color all that much, it looks nice online but not so much on my person, so I’ll probably buy another one in another color that goes better with my outfits. I like it enough that I’ll still use it under my clothes, if the colors don’t match to wear it over. ... show more

  • Lightweight and ultra-useful!!
Color: Navy Blue Size: 2L
I love this product!! I use it for international backpacking. An internal pocket is perfect for passport and a critical information page (credit card info, Global Entry card and flat items not used daily). There is ample space to organize essentials like coin & paper money, credit card, phone & charger cable, lip balm, sunscreen, etc. It is durable, but extremely light weight. A great gift for the hiker/backpacker in your life. (And back home it often replaces my purse on daily errands.) ... show more

  • Perfect to take to a show
Color: Grey Size: 2L
I got this for the particular purpose of having something I can take to stadiums, ballparks and the like because my phone is big and heavy and I don't want to carry it in my back pocket for the entirety of a rock show, for example. This pack can be made tiny to be brought in, and then you can easily unpack it and stuff it to carry things like a phone around inside a venue. It's held up nicely over the course of several shows this year. The size is like a medium-sized fanny pack. ... show more

  • Not a very long lifespan
Color: Blue Size: 2L
This is a lightweight and fairly comfortable pack with a very good number of zippers and compartments which was helpful. This was used for 6-8 hour retail shifts 4 days a week in a moderate use environment. Sadly little holes the fabric became apparent fairly quickly and although a bit of tape and glue allowed it to hold out —now—approximately 10 months post putting this into use— the bottom of the main compartment has begun to disintegrate. I wanted to give an idea of the possible lifespan of this item as I wish I had more info at purchase. ... show more
