Updated Terrapin in stock now!

Posted by Eric Parsons

We released the modular Terrapin system a few years ago. It was the first bikepacking bag system on market to combine a removable waterproof drybag with a holster like mount. We’re happy to release this updated version that improves upon the original in a big way.

First off – It generally looks the same, the main differences are in the stiffening components and the main closure.

First off, we steepened up the seat post angle to prevent buckling of the lower section and to keep the rear of the bag more level. The side panel stiffening was switched from plastic to a thin resilient foam to solve some some creasing and wear issues we’ve seen with plastic side panels. The stiffened side panels still feature a pair of thin fiberglass stays along the edges so the mount does not warp under compression forces. Lastly a pair of abrasion guards was added under the main mounting buckles. The front seatpost attachment now has an alloy loop for ultimate strength when tightening down.

The next big improvements come at the rear.

Gone is the single strap that needed to be double over in favor of a joined, 2 strap and buckle system. This system is simpler and easier to open and close than the original.

Lastly we added stiffening elements to the main mounting panel which significantly reduces lateral sway.

All this gives you a super versatile platform for carrying stuff and keeping it dry (or separated if wet) with no hardware to mess with.

Thanks for checking in!
