Z-Light Small 

This tiny looking saddlebag from the French brand, Zéfal, is like Dr Who’s Tardis! It may not look like it can take much, but it easily accommodated and inner tube, the Lezyne SV-11 multi-tool, 2 Park Tool tyre levers, a Lezyne patch puncture kit and a single gas canister.

The bag is fixed to the saddle in the more conventional way, with a velcro strap that runs over the bars, which is then tightened on the sides. There is no velcro fastening for the seatpost, which was initially a concern, but the saddlebag was clamped tightly to the base of the saddle and there was no movement when riding, which the tester anticipated, which may be due to the stiff inserts on the top and bottom of the bag that provide stability, whilst also stopping the bag from compressing and losing its shape.

Compact, roomy, with sufficient reflective detailing and a waterproof zip to guard against water ingress – the Z Light Pack packs a big punch and at only 50g, the weight weenies will love it too!

The Zéfal Z Light Pack (small) is also one of the cheapest saddle bags on the market.
