BTR Bicycle Bag Gen2 & Mobile Phone Holder

I purchased this bag to use on my summer and winter (the rain cover is great) Audax cycling rides. It has many features that were appropriate for me. It is big enough for my needs and is not to big that it rubs off your legs. It is big enough to hold a power pack; a phone, money, food and a tube of nutrition tablets. I use the power pack to charge my phone and Garmin through a small outlet and the phone is accommodated in an inside pocket; which is visible through the plastic front. Very reasonable price and very efficient delivery

After a long search ... just what I was looking for ...

Great quality product, exactly as described, well made with appropriate adjustable straps that provide a secure snug fit on to the cross-bar. Able to operate my phone through the clear plastic cover with an easily accessible cable port for headphones etc. - very helpful features. Have tried a number of other similar products from other outlets/manufacturers none of which have proven fit for purpose with longevity being something clearly missed by the product designer(s)!
