NEWBOLER Bicycle Saddle Bag Bike Seat Bag Under Seat Packs Tail Pouch Cycling Road Backpack10L

I bought this bag to carry my sleeping bag while bike camping. It's much more reasonably priced than name brand versions of this type of bag and it seems very high quality for it's price.It has a few small touches that really stood out as soon as I opened the package. The side straps that keep the bag closed have “keeper” loops sewed on the ends. This keeps the extra webbing from getting into your wheel or flapping around. I also like the shock cord on the top of bag which allows for carrying light items like water shoes or a rain jacket.I put my hose on the shower setting and held it on the bag for about a minute. The seams inside of the bag aren't taped so it's not fully waterproof, it's more water resistant. It's unlikely it would survive being fully submerged without the contents getting wet. It did survive my hose test with nearly no water getting into the bag. I may tape the seams to see if that makes the bag fully waterproof as I don't want to use a liner in the bag or end up with a wet sleeping bag.Mounting the bag was dead simple, same as smaller bike bags that most riders are probably familiar with. One wide strap is secured around the seatpost while two smaller straps are secured under the saddle rails. Once mounted the bag feels solid and doesn't move side to side too much. Over bumps it does sway but without a frame that's going to happen with any large seat pack. I didn't feel the bag at any point while riding.I will update my review in regards to durability as I get more use on the bag.

If you're looking for a great afternoon bag that will hold light items for a short trip, this thing is great! However, I purchased it in the hopes that I wouldn't have to pony up for an Apidura bag or something similar on a double century bikepacking trip; well, the verdict is out because the value is great but it leaves me wishing I had put this money toward something higher end.PRO:It's inexpensive and made of relatively water resistant material.It's easy to setup.CON:It cannot hold weight - it folded and sagged as soon as I put anything heavier than an item of clothing past the bottom plastic structure that extends out from the seat post attachment to around 8 inches. Past that, the whole things flops down now matter which way you roll the bag up or how tight you make the straps.Additionally, the side pockets will fit maybe a Clif Bar or a small multitool but beyond that, they are basically for show once the bag is packed.Since there is not a flap on the end of the bag as many waterproof bags like this have, allowing for a firm closure, no matter how you roll this bag it seems to be wrong.The last issue I had was the webbing, it ripped almost immediately with a 10g tail light attached to it while going over a bump in the road, I was able to recover the light but...that's disappointing as well.These are my opinions and I doubt the manufacturer will invest in improvements but in the end I know this bag's limitations and will use it as such.

Very pleased with this product. I recently purchased as an alternative to other similar products from "Name Brand" manufacturers. Nothing wrong with those, but they are very expensive and I wasn't sure I wanted to spend that amount. I bought this as a cheap "test" figuring if it worked and I like it, I'd buy a similar but high quality bag. I used it on a long overnight bike packing trip, bouncing across miles of gravel Forest Service road. I also just completed a 6 day bicycle tour. This thing is one of the best inexpensive pieces of gear I own. One the bike packing trip, I packed a full size fleece jacket in it, and a wind breaker. On the bike tour I packed arm warmers, leg warmers, windbreaker jacket, a couple of extra tubes and a few other smaller items. I never had it close to full. It also rained all of one day, a miserable 40 mile slog through cold rain. Every bag leaked to some extent except this one. Even my Axiom Monsoon panniers had water inside and they cost well over $100 bucks. This bag seems well constructed, nice functional straps and clips and works well with my Brooks saddle. It has some little zippered side pockets that are so small as to be virtually worthless though I did use the two rear ones for some extra straps. The zippers on the pockets seem sort of cheap and I doubt they'd hold up to much use. The roll down closure is very functional as it self adjusts depending on the load you have packed in it. It is also cavernous for such a small bag and it is amazing the amount that can be packed in with a little forethought. Again, very pleased with this saddle bag and after buying it as a temporary "test" , I have no need to replace it with one of the high dollar "quality" bags.

The straps come loose on the smallest of bumps. They won’t stay tight and at this point it’s a worthless pack because I don’t trust it to stay tight to the bike while riding singletrack

One of the reasons I picked this bag, was cause it did not need to be the full size. I did not want to have a bag that long in back of the bike. Good to know that I had extra space if I really needed it. Important to note I also used a Velcro Strap with the bag to help secure it. Seems like these bags should include a seatclamp instead of a strap which could give them better stability.

this bag starting falling apart on the first day of a 7 day bike trip. The stitching is very weak on all the straps and will fail and pull apart if you are offroad or on a dirt road. Don't buy this bag for mountain bike trips it is definitely not strong enough. The materials and construction are cheap and won't last long

It's a nice bag, but I ended up returning it after deciding it was probably too big for how much stuff I would really put in it. I didn't really like the way it rolls up when it's not completely full - doesn't seem secure enough to not unroll.

Get what you pay for. Straps came loose 4 miles into first ride (had a jacket, a small backpacking sleeping bag and a few small clothing items in it) fell onto the back tire and melted/shredded a big hole and tore a big hole thru a pricy jacket.
