I totally understand where you're coming from with the Rapha roll top backpack. It’s definitely a sleek choice, and I've seen a few people swear by it for cycling and urban travel. From what I gather, it's designed with a blend of style and function, perfect for more city-centered adventures rather than rugged backpacking trips.
However, for long-term backpacking, functionality should take precedence over aesthetics, unless you find the sweet spot between both. In my experience, durability and comfort for long carries are non-negotiable. I’ve traveled extensively with an Osprey Farpoint, and I found its ergonomic design really reduces strain over extended periods. It’s also pretty reliable in wet conditions, with good water resistance, although I’d recommend an additional rain cover if you're planning to trek in very rainy regions.
Deuter is another brand I’ve had good experiences with, especially their backpacks geared towards hiking—lightweight yet robust. The Deuter Futura series, for instance, has a solid frame support and excellent ventilation, which is crucial if you’re going to be in hotter climates.
If you're keen on keeping things budget-friendly, you might want to explore second-hand options or outlet stores. Sometimes you can find top-notch gear at a fraction of the price. Online platforms like REI’s used gear section or even local gear swap groups on social media can be gold mines.
Have you figured out how much gear you'll be carrying? Sometimes, the weight distribution and the actual items you're packing can influence what sort of backpack will best suit your needs. If you're not carrying too much, a smaller, versatile backpack could very well do the trick!
Are there any particular features in the Rapha backpack that you're especially drawn to? That might help narrow down alternatives that won't break the bank. Let me know if you want more detailed suggestions, and I’d be happy to help further!
