XUL (extreme ultralight – gear philosophy)
Overview
XUL, or extreme ultralight, is an informal gear philosophy focused on minimizing carried weight beyond standard ultralight levels by using highly pared-down equipment systems.
Key points
- Describes a style of packing where base weight is reduced far below conventional backpacking norms.
- Emphasizes multi-use items, very small gear selections, and careful tradeoffs between comfort and weight.
- Often assumes specific conditions, seasons, and personal experience with minimalist systems.
- Can reduce strain and fatigue for some hikers, but may feel spartan or uncomfortable for others.
- Not a formal standard; the exact weight thresholds associated with XUL vary by community and context.
Details
The term XUL (extreme ultralight) is used informally to describe gear setups that reduce base weight to levels considerably lower than typical ultralight kits. While there is no universally accepted cutoff, the label generally reflects an approach where each carried item is evaluated closely, redundancies are minimized, and some comfort-oriented gear is intentionally left behind.
XUL systems often rely on lighter fabrics, simplified shelter designs, smaller cook or no-cook setups, and very focused clothing choices tied to specific climate expectations. They may also depend more heavily on experience, planning, and local knowledge, since backups and extras are limited.
The philosophy is not inherently better or worse than other approaches. Some hikers find that very low pack weights reduce fatigue and make long days more sustainable. Others prefer the margin of comfort, warmth, or redundancy that slightly heavier setups provide. Suitability depends on route, season, available resources, and personal preference.
Because the term is informal, XUL are often understood as a descriptor of style rather than a fixed label. Hikers adopt, adapt, or decline XUL practices based on their own goals, comfort levels, and risk tolerance while remaining mindful of safety, regulations, and environmental conditions.
