Great bags!

I'm very happy with these bags. There are easy to get on and off the bike. They fold small but have a lot of potential for big loads when we go grocery shopping. I love that they are full waterproof and have little things to attach a light/reflector.

Great buy

Love this bag. Super easy to fit onto my bike .Useful size for carrying my gym gear or a few things from the shop . Easy to pack flat .

Good, but not great

This is a good little pannier, just beware that the mechanism for securing it to the bottom of your rack is just a bit of Velcro which isn’t big enough to get a secure hold on all rack shapes. It is not a problem most of the time, but I did have a washout and the pannier came off the rack.

Excellent Pannier bag

Great design and waterproof makes riding bike enjoyable. A fellow bike rider has bought the same product based on my recommendation.

Why did I wait so long

I put this pannier on my rack, after one year of commuting. I'm not as sweaty when I get home & I get home faster. Should have gotten one much, much sooner

Absolutely Awesome

I don't know what you people are talking about. Did you stab a few holes in them with a knife and then force a garden hose in there or something? I took 2 of these panniers on a 12 day motorcycle tour of northern Vietnam in some of the most torrential rain I have ever been in and everything inside the panniers were bone dry. Sure, they needed the mud and stuff cleaned off at the end of each day (which I did in the shower BEFORE taking anything out of them) and they were brilliant. They were flexible enough to be strapped on to the side of the bike in any configuration and were ALWAYS completely dry at the end of the day. Check out the yellow ones if these are being discontinued. You people complaining about their lack of waterproofness mustvmu been riding round with them wide open as well. Fantastic buy!

Surprisingly voluminous!

It handles a 15 lb bag of kitty litter with ease.

perfect as always

I ordered the bag 2 weeks ago and on tuesday I was doing a shopping trip with them for the first time. They were super easy to put on, with a screwdriver I was able to adjust it so that it fits my bike perfectly. Even with maximum speed there is no risk for the bags to fall off the bike. I wish I could have bought the yellow one but sadly they were sold out. But as always i'm super Happy with the service and the product. Well done Decathlon

A Stylish And Affordable Pannier Bag

These pannier bags are stylish and well made. The seams seem to be welded together, so they should be well protected from the elements. (I’ve only had my pair for a month and we’ve had no rain so haven’t fully been able to test this). The bags feel sturdy and have a good weight to them. They are definitely a step up from my Lidl Crivit Bags, that were cheap, had some good features, but ultimately fell apart after a year or two. The bags are feature rich, having adjustable clamps for attaching to your rack. Plus attachments to further secure the bags on your rack and stop them from flapping about. My only criticism is that there is no internal divider for a laptop and no small zipped compartment for small items. Even so for the price, these are very capable pannier bags. 👍

Good Pannier for commuting

I bought this pannier to replace a very old drawstring closure pannier. Its taken a little while to get used to the different type of closure with this pannier which is a little stiff to bend at first but after a few uses loosens up. I've used the pannier on my bike in light rain & found everything stored inside kept dry & the rainwater beads formed on the pannier so it is water repellent. Really easy to fit to my bike rack as soon as I walked out the shop and there is enough room inside for about a basket worth of grocery shopping. Good value for the money.

Great value for money!

I’ve been using this for a good few weeks & highly recommend it. It’s not rained much so can’t really comment on waterproof but it was fine when riding in a light shower. I use it to commune to work so am carrying change of clothes, food in Tupperware, laptop etc and despite going over some very bumpy uneven roads, it all stays intact! Looks great but just a shame there’s no internal pocket and or carrying strap to carry on the shoulder however for the price it is, a complete bargain.
