Rab says: 

Move fast, pack light, and defy the elements with the Veil XP. This ultralight, versatile, fully waterproof 20L pack is equipped for fast-moving pursuits in unpredictable conditions. Tested to IPX4, it combines taped seams and waterproof fabric to protect your kit in the range of mountain weather you face on a multi-day trip. This further reduces weight by eliminating dry bags from your kit list. The Veil XP is fine-tuned to keep you moving, with on-the-go access to gear and a 3D mesh back system that wicks away moisture, flexes with you, and remains comfortable over distance. Built with intrepid runners and fast hikers in mind, it’s geared up for everything from ultralight fastpacking to mountain marathons.

Our Verdict

At 459g, the Veil XP 20 is a stripped-back, fully waterproof pack that feels purpose-built for fast hiking and high-output days in mixed conditions. The vest-style harness fits close to the body and stays put, even when moving fast across uneven ground. Each side holds a 500ml soft flask and features a zipped pocket for secure essentials. The breathable mono-mesh and 3D spacer back panel keep things cool and comfortable during extended efforts.

Storage is smart for the size. The large front mesh pocket is perfect for stuffing a wet waterproof or quick-access layers, and the side pockets—one zipped, one open—are easy to reach while on the go. A simple pole sleeve adds to the fastpacking credentials, keeping things stable and accessible without extra weight.

The roll-top main compartment is IPX4-rated with taped seams, which means no faffing with dry bags. The dual sternum straps and minimalist hipbelt keep the fit dialled without overcomplicating things.

A no-nonsense mountain pack for moving fast in any weather, when every gram and every second count.
