After a shoulder op I find wearing a back pack very uncomfortable ( feels like the straps are made of thorns) and have resorted to using water bottles, a small seat pack and pockets for the essentials.
Now I have built an all day road / cx bike I want a seat bag to carry my things like a jacket, food, spare tube and tools and even the bare essentials if I do an overnighter (credit card style).
I like the look of the revelate ones but seem they may be a little difficult to get hold off and pricey
Wildcat ones look good and uk based, reasonable to higher price but maybe worth it if the quality is high
Polish Bikepack looks good, again non uk so could again be a little hassle getting hold of
Finially Ortlieb large classic looks good, not sure on total carry size but price seems good.
Any recommendations or any I have missed?
