after buying the aero-pack , I completed my traveling set with a pair of UD pannier bags. The product is up to Tailfin standards both in terms of quality and style. I had already the occasion to test them in multi days adventures in rough weather and I’m very satisfied. The lock in / unlock system is quite amazingly manageable and useful.

Great quality
A Belgian friend of mine recommended tailfin. I borrowed his equipment and made a trip through Germany with it. It’s practical, light, and great quality.

Rock solid but elegant bike packing outfit
I got me the tailfin rack, top bag and ultra durable pannier bags combination. It carries my full and complete bike packing gear, in a rock solid manner, without making my bike feel or manoeuvre like a rock.
