If you're looking for a bike seat pack that can hold all your riding essentials without weighing you down, then have a look at theTimbuk2 Medium Seat Pack. This pack is 90 grams of ballistic nylon gold that will protect your gear and help you keep it organized.
Ballistic nylon is weather proof and super durable
.8 liters of storage is big enough for tube, tools, nutrition, etc.
"Medium", is relative so, I don't know why the other reviewers gave it only 2 stars because it wasn't as big as they thought it would be. I purchased it because it is a bit smaller than the bag I was using. I needed a bag for a tube, car key, and a few small tools. It fits the bill perfectly, looks great, and fits nice and tight under my saddle. I carry my phone in my jersey pocket, so no need for that to be in my bag. I have a (forget what it is called) strap that wraps around the tube and tire levers. It keeps them tight and compact and makes for a bit more room in the bag. So, if you need a bag for a few things for group rides and shorter rides, this is a great bag.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
