The Godfather of seat packs! This 17 litre beast will carry kit all day long with no sweat.

Based on our original Koala but made larger for longer, more remote rides. Koala has been to the gym and come out stronger, albiet it at the cost of a few extra grams. We have beefed up the attachment straps and reinforced the contact points to fend off wear. Super tough Cordura wraps around the base of the pack for durability and we have added a cord triangle to tie down your waterproofs or flip flops. A tough aluminium buckle adorns the top strap so you can synch everything down nice and tight for a stable ride.

Made from durable and highly water resistant VX21 and 1100d Cordura.

Excellent bag with color matching my bike

The bag is solidly built with wide color range, I immediately bought one when I saw it available in yellow which perfectly matched my bike.
Most the straps are well built and offered plenty of adjustability except for the seat post straps which are way too short for my Trek bike. I have to cut some Velcro strips for extension. However, since I use the bike for daily commute between office and home, so the strap extensions should be no issue except for the look; for that only 4 stars.


This has been used on three bikepacking wild camps so far with various combos of kit packed into it.. This has included:
British army bivi bag, Exped synmat winterlite LW,lightweight down jacket,inflatable pillow.
DD hammock,and suspension straps/carabiners,Exped mat,above jacket and pillow.
DD jura2 sleeping bag by itself.
Make sure the available strap crossover under the saddle rails to prevent sway.All in all, a great seatpack.

First impressions- EXCELLENT!
Bombproof feel and construction to this product. Stitching quality is excellent with no loose raggy ends. Buckles top notch and the open aluminium style is a great time saving idea.
I look forward to stuffing my hammocking sleeping bag into it and updating my review next week.
