The Salsa EXP Series Saguaro Seat Bag is made for the kind of terrain that rattles lesser bags apart. Its four‑point rail connection locks the bag into your saddle with exceptional stability, eliminating sway even on tight, technical trails. The modular holster + dry bag system makes packing simple and keeps your gear protected, while the one‑way purge valve lets you compress the load for maximum space and a clean, quiet fit.

Saguaro works with both the Medium (9L) and Large (14L) dry bags, so you can size your storage to the adventure. And because it’s dropper‑post friendly, you can ride steep, chunky lines without worrying about your bag contacting your tire. Pack it, cinch it down, and go find the wild stuff.

Why this bag works

Saguaro solves the biggest problems with seat bags: sway, moisture, and awkward packing. The holster keeps everything tight and stable, the dry bag protects your gear from weather and river crossings, and the purge valve lets you compress your load so it rides quiet and compact. It’s a dependable choice for riders who push into rugged terrain and want gear that stays put.

Perfect for

• Riders tackling rugged, technical routes where stability matters
• Bikepacking setups that need modular storage for different trip lengths
• Dropper‑post bikes that still need rear cargo capacity
• Anyone who wants a durable, weatherproof seat bag that won’t sway or sag
