Update: We have a batch of Picketposts available! We are offering them unsealed to keep the price down for those who don’t need it or wish to seam seal themselves. If you want us to seam seal it, you can pay for that with this link.

The Picketpost is a bikepacking style seatbag, expandable in size with compression straps.  It is designed specifically for hardtail bikes, and maximizes use of the space behind the seatpost. It requires at least 7″ of exposed seatpost to fit.

The bag has a plastic stiffener on the bottom and can compress vertically with straps to your seat rails.  This helps to avoid rear wheel interference on bikes where clearance is tight, and it also adds some stability to the bag.  The bag closes with a roll top from the rear, which allows for more control over the volume.

The Picketpost ships without seam sealing, but we can seam seal it for an additional $30 (which you can pay for with this link). Or you can seam seal it yourself – simply remove the bottom stiffener, turn the bag inside out and seal all of the stitching with Seam Grip, Aquaseal or another urethane-based sealant.

The Picketpost has a minimum packed size of 6 liters (a bit smaller if you remove the bottom stiffener) and a maximum of 13 liters.


The Picketpost is named after one of the best sections of the Arizona Trail.

Weight 16 oz

6-13 liters
