Looking for riding backpack recommendations! 🏍️

I usually do 3–4 day bike trips, so I'm looking for a good riding backpack with decent comfort, durability, and enough space for clothes and essentials.

- Budget: Around ₹7,000

- Bike: Triumph Scrambler 400X

- Prefer something comfortable for long hours and, if possible, water-resistant.

If you've been using one for touring, I'd love to hear your recommendations and experiences. Thanks!
