Waterproof Bicycle Saddle Bag Bike Bag Under seat Bag Rainproof Mountain Road Bike Seat Bag Bicycle Bag Professional Cycling Accessories

I’ve Had mine for 6 months now and it’s still in perfect condition . I Use mine for commuting mainly, around 120 miles a week , this bag is well suited for bikepacking too.It has a large capacity and i have ridden in several heavy storms and it is fully waterproof. I can fit 2 pairs of pants,2 shirts,one light jacket, a full bike repair kit , 1 pair of socks & a small size gym towel . 2 things to note, when fully loaded with gear there can be some significant sway when sprinting out the saddle , this can be solved by a good Velcro tie down that holds with rubber grip . Secondly , it’s not a big deal but more straps to tie down or tie stuff to would be a plus I think . Other then these minor complaints it really is a perfect & durable high capacity saddle bag . I recommend it for sure !

Good sized seat bag for everyday use. For reference, I’m able to fit all of the following at once: one tube (700x25), a cycling multi tool, two tire levers, a Swiss Army knife, a wallet, a small notebook, an iPhone 7 (no case), a set of earbuds, a pen, two energy bars, and a set of keys.

This seems to be a solid little bag. I'm planning to use it as part of 2-night bikepacking trip on a full suspension, dropper post MTB (+ large framebag and large handlebar dry sack).--- Bag size ---This really is just a 1.5L bag. Definitely not the 2-3L claimed. It's not possible to expand because of the current buckle system. When testing what I could fit in it, I was able to fit two 27.5 tubes, small patch kit, multi tool, and tire levers with just a bit of space left over. I'd bet you'd be able to also fit a few CO2 cartridges and / or small pump. I think a roadie would be totally fine fitting everything they need in (two 27.5 MTB tubes take up a ton of space). (this bag is still larger than most other normal saddle bags!)--- attaching for a dropper ---I was able to make this work without interfering with my dropper post by connecting the seatpost strap to my saddle rails, just before the saddle clamp. The seatpost strap is all velcro, so it's easily adjusted to make this work. Then connected the main strap as normal.I also needed to push my saddle back as far as possible in the clamp, but I like this riding position anyways. The end result is that the bag sits higher up and farther away from the seat post.NOTE: IF YOU CAN, wrap the primary straps around the saddle rails multiple times. I was able to get two wraps in while still having enough length to buckle everything. By wrapping multiple times, you greatly reduce the potential for bag sway while riding.--- material / build quality ---The material is a heavy laminated fabric that reminds me of old-school dry bags (the heavy, PVC style ones, not the modern ultralight dry bags). The fabric doesn't stretch at all, so the current size is really all you get. Based on the cost, I'm expecting some of the seams and welds to eventually fail, but the material itself is solid. Some of the fabric seems poorly cut (ie not necessarily ultra straight edges everywhere) but this doesn't affect the function of the bag.Note that there is a plastic component in the bag to help hold its shape - I didn't see this mentioned anywhere prior to purchase. It's a plastic "U" of sorts - looking the side of the bag, the "U" sits sideways and reinforces both the top and bottom walls. This helps maintain the bag shape when you cinch down on the straps.The nylon straps feel pretty smooth, so I wouldn't be surprised if they loosened up slightly over time. (I haven't had the bag long enough to test this out, though)--- design complaints ---- the rolltop buckles are both male, rather than one male / one female. This means that you effectively HAVE to roll the bag down all the way, to reach the female buckles on the sides of the bag. So, the bag isn't expandable at all (not that you'd get much more space anyways, but still). I wish the bag worked more like a standard drybag.- the nylon straps could be a little bit beefier, and I'm concerned they'll loosen over time because they're too smooth.- the stitching connecting the straps to the bag seem fine, but only just fine. I think they could have used a bit more stitching to really make it a bomber connection.- I'm not totally sure I trust the tail light strap. It's likely fine, but if the welds are weak, the strap would be toast. The fabric for the taillight strap seems much thinner than the rest of the bag.--- conclusion ---Overall, this bag fits my use case: water resistant, seems to be dropper compatible, and can fit a repair kit. And I don't think you can find a better bag for price.

I purchased this as I wanted a single saddle bag that could hold the following:1. Spare tube2. Tire levers3. Quick patch kit4. Multi tool5. My wallet6. iPhone 7 Plus7. Car keysI was tired of other saddle bags that couldn’t fit my phone very well, and figured if I was going to switch I’d get one bag to replace the old saddle bag and top tube bag setup I had been using.This Rhinowalk bag does the trick perfectly!!It was easy to mount to the seat, stays securely in place, is easy to get opened and closed...and most importantly it holds everything I need it to with a bit of room to spare.I also like the way it looks. It’s kind of rugged looking.I haven’t tested how water resistant it is, but I have other bags made of similar material with the roll style closure, and they do an excellent job of keeping things dry...so I have no doubts this bag will keep things dry as well.I like it so much I’ve ordered two more for two of two of my other bikes, and will be ordering another for my fourth bike soon.Highly recommended.

My son's Explorer Troop recently went on a 30 mile bike camping trip. Instead of panniers, I purchased this for him to transport his sleep system. He was able to fit a hammock, two down quilts, hammock straps, and an inflatable pillow in this bag, and compress it down. He put a hoodie or jacket in the shock cord straps while riding. (The rest of the gear went in his hydration pack or in a handlebar bag.) He said it was easy to pack, easy to attach, and easy to ride with in on. It did not sway or droop onto the tire at all. He said he only noticed it getting on or off the bike as he swung his leg over it. There was a faint drizzle when he started the ride and the content stayed dry. No issues with anything getting wet due to condensation in the cold. A great purchase for his needs!

今更ながら（2019/10/16）に追記。チューブラータイヤを入れるのに使いましたが、ペダリング時に太ももにバッグの頭が当たってダメです。他のものと比べると、2.5センチは広いです。別ページの同商品もだけど、なんでこれが高評価なんだろう。折りたたみ自転車をカスタムしたことなどもあり、容量大きめのサドルバッグを試してみようと思い立ち、注文。一応、フォグリアのMサイズとカインズのPBを所持。これらはジッパー式なので、ロールクロージャータイプは初。届いてロゴを見ると、オルトリーブとそっくりで笑いました（商品写真でも確認できますね。OUTDOORなんかも似たような感じなので、商標権は特にないのかも）。本題。素材はPVC。ウエストバッグの内側なんかに使われているビニール風生地の厚手版といった感じ。それが裏地なし一枚です。この類の素材、個人的に耐久性が良かった記憶がなく、曲げ負荷がかかったところからことごとくクラックが入ってボロボロ剥がれ落ちていくような生地です。使用感を見るために数度開閉をしましたが、すでにその傾向が出始めている感じも。というのも、巻き込みが非常にタイトなのと、ロールクロージャー側バックルのメス側が微妙な角度でガッチリ固定されていて、バックルを差し込むのも斜め下+一枚外側くらいの位置から無理やり押し込んでいる状態になっているからです。生地自体も厚み1mm以上ある感じで、柔軟性はほとんどありません。そもそも、巻く段階で左右生地は2枚に折り畳まれているわけで……というか、商品説明画像通りに収めようとすると、一回折り返しただけの上に口が上方に向いてしまうと思うんですけど、これでいいんですかね？PVCは加水分解という宿命を抱えているわけで、まあそれ自体は2〜3年は余裕で耐用できますが、構造の問題で寿命は短そうな気がします。素材自体の防水性は確かでしょうけどね。と言うか。もう一つさらに大容量のサドルバックも注文して、そちらも口の両側にオス・バッグの両側にメスという同様の構造だったんですが。この構造、固定力が悪いし安定もしないし機構が無駄に複雑になるしでいい事なにもないと思います。オルトリーブの機構（現物に触れたことはないですが、口の左右にバックルのオスメスがあるように見えますね）が特許出願されているのかもしれませんが、それならそれでマジックテープで段階的に止めるとか、ベルクロで縦に絞るとかの構造にしたほうが結果的に品質や原価の面で有利なのではないかと思います。このレビューを書いている時点で在庫なしに近い状態になっているものの、同一商品が他にあるので、少しでもそちらの参考になればなあと。他のレビューが高評価ばかりなので、自分の使用方法が間違っている可能性もありますが。

日帰りツーリングを想定して購入。スペアチューブ、ミニツール、パンク修理セット、タイヤレバー（プラスチック）2本、ミニポンプを入れて見ました。チューブがもう1本入りそうなスペースが残っています。控えめなデザインで、私のクロモリロードにも違和感なく収まっています。値段も安く、万が一破損しても、精神的なダメージが少なそうです。

トピークのMサイズを使用していたが容量が足らず、少し大きいサイズのモノを探していたらこの商品を見つけ、価格も安くデザインもまずまずなんで、ダメ元で購入。予備チューブ始めパンクキット、予備ロック、ゼリードリンク、バーフード、財布など前のバッグでは入らなかったものが入り満足。袋を閉じる際にコツが要る点で-1点も慣れの問題なのと、価格、デザイン、縫製もしっかりしていて大満足の商品
