Buying advice

When choosing an ultralight backpack, consider your typical load weight: frameless packs are best for under 20 lbs, while frame packs support more. Durability vs weight is a trade-off; Dyneema/CF is lighter but pricier and less abrasion-resistant than nylon. Check fit and adjustability, as comfort is key. Waterproofness and pocket accessibility also matter.
