Klim Nac Pak 3L Hydrapak® Backpack - Olive

I’ve got a fair bit of Klim gear now and this Nac Pak fits right in – literally and stylistically. I wanted something hydration-compatible for longer days out, but didn’t want a huge pack flapping around or looking too “MTB bro”. This nails it.

The 3L Hydrapak reservoir is spot on – doesn’t leak, easy to clean, and the bite valve works exactly as you'd want. The included tool roll is a genuinely nice touch; it’s not just a gimmick – it’s proper, and makes storing essential bits simple and neat.

Fit-wise, the harness system is excellent. Once it’s on, it doesn’t shift about, even when I’m riding in a more aggressive posture. There’s a waist strap too if you want to really lock it down.

It feels rugged, looks great in olive (matches my Marrakesh jacket better than expected), and the internal compartments are well thought out. You can chuck a wallet, power bank, keys, a bit of food, and still have room for the hydration bladder without things feeling cramped.

My only small gripe? Like most Klim bags, the loose ends of the straps can flap if you don’t tidy them up, but it’s a minor thing and easily sorted.

If you ride in Klim gear and want a no-fuss, tough daypack that doesn’t shout “cyclist”, this is a really solid bit of kit. Recommended.
