The Black Diamond Betalight 30 Backpack is extremely durable and customizable, offering incredible versatility for everyone from casual day hikers to minimalist backpackers. The bag is made of Ultra 200 fabric, which is tear-resistant, waterproof, and light, so we can confidently stride into any adventure, knowing our gear will make it through. The hip belt, compression straps, and frame pad can all be removed to cut weight, and the roll-top closure minimizes pack size and bulk. The large front pocket stores extra layers or other larger items, with two mesh side and two zippered hip belt pockets to organize our smaller essentials, allowing us to maximize the small internal pack size.
