What to Pack in Your Seat Pack

The most important thing when packing a seat pack is to be careful not to overload it with heavy items. Doing so will throw off the weight distribution of your bike and make riding more difficult. 

How to Pack a Seat Pack

• Put only lightweight items in: Most experienced bikepackers put bulky, lightweight items in their seat packs, such as clothes, rain gear, a sleeping bag and a folded sleeping pad. Go ahead and stuff these items straight into the pack without using stuff sacks (this saves weight and is the easiest way to fill every square inch of the bag). If your seat pack is not waterproof, make sure items like your sleeping bag and clothes are packed in a waterproof stuff sack before putting them in the seat pack.
• Place heaviest items closest to the seat post: This can help limit the amount of side-to-side sway that can sometimes occur with a seat pack.

Keep in mind that access to your seat pack is not terribly difficult, but it's also not super quick and easy, so you don't put anything back there that you'll need frequently throughout a day of riding.
