A sturdy construction even when full and attached on the saddle. Great in all types of weather.

Great design. It’s like a small dry sac with a roll down clip closure.

Only one drawback

Excellent size, and seems good quality. Only issue is the difficulty in tucking the opening away when riding.

Good in parts

Bag itself is good, well made. Access is a little constrained as the 'neck' is narrower than the largest part of the more rigid bag. Keeps water out. Geometry of the fixing is however poor. The saddle rail straps (on the top) are too close to the small end so the seat post strap must be fastened just below the saddle, exactly where it is likely to rub against your shorts. The hard edges of the strap then rub thro the short fabric...not great. One pair of shorts damaged after 100km ride. Bag is big enough to move saddle rail straps closer to opening end and hence allow the tube trap to sit further down.. more akin to the larger bags from other makes, or a different post strap arrangement that is thinner (ie not a velcro strap). To avoid this damage I have used duct tap over the seat post strap to avoid the edges causing damage. O

Useful bag

Although it fits under the bike-seat, the bag is big enough to hold my bike-lock and other essentials and it's comforting to know it's waterproof. Being of soft material makes it more flexible, but probably less smart.

Great design but saddle strap failed

I have been really happy with this bag, 100% waterproof, roomy and without sway during the winter months last year. Until today that is, one of the velcro strapt that holds the bag to the saddle rail has failed, ripped in half. I have checked my rails, no sharp edges (fizik Kurve snake).

Dear Sir,
I agree with you that this is a great bag. I use one myself for very long days out on my road bike. However I'm disappointed to read that the strap has broken.
I will forward this on to the design team at b'Twin.

Not waterproof!

There is a reason it's cheap. Great in the dry but leaks like a sieve in the rain - holds a lovely puddle of water inside though just to make sure all your things stay nice and wet

I'm sorry to read that you had water inside the bag. The fabric itself is waterproof and the seams are taped. I wonder if there was actually a hole in the fabric. Please return the item to us and we can refund/replace the item for you.

Excellent value for money.

Bought mine in June and it is a proper investment. Can throw all the repair stuf needed in there, plus keys, phone, gels etc etc. Leaves my pockets feeling far less weighed down! Only gripe would be about the closure as this is a bit messy. But all in all a great bag.

Straps ripped

Bought this less than 2 months ago. Have only used it for commuting to work a couple of times and the straps have failed. Its a shame as it's a good size and is very waterproof. If i still had the receipt i would exchange it for another and modify the straps to improve it.

You can still return this item even without a receipt as it exclusively sold at Decathlon.
