Help me out here:
This appears to compete in the Osprey Exos 48L space, where the Osprey pack comes in at 2.4lbs for the Large pack size at the same MSRP. For the additional 0.6lbs in weight, what are the Ultra-lighters getting in terms of features from the Kelty vs. the Osprey? I don't want to pick nits here and sound like an elitist, but this seems like a poor deal for Ultralight hikers when comparable bags are out there offering a similar price/capacity ratio at a lower base weight.
bioshockerlol I would say that the main difference is that the Kelty fabric is 330d compared to the Osprey using 100d. Fabrics denier is not a linear in terms of durability - 330d is probably 5-10x more durable than 100d, all else being equal. The Siro has a very nice front opening zipper for easy access to the full pack. And the angled water bottle pockets are pretty cool. So I'm actually surprised that the Siro isn't more popular. Osprey dominates the backpack market.
DannyMilksThe angled water bottle pockets are super handy! It is one of my favorite features of this pack. One smart water bottle on either side, or just one for shorter hikes.
