Ultralight backpacking minimizes pack weight (base weight <10 lbs, ideally <5 lbs) through gear optimization, eliminating non-essentials, and embracing discomfort for efficiency. The philosophy (popularized by Ray Jardine 1990s, Andrew Skurka 2000s) became Instagram/YouTube culture (2011+) through gear reviews, lighterpack spreadsheets, and “big three” obsession.
Philosophy & Approach
Base Weight:
- Everything except consumables (food, water, fuel)
- Traditional: 25-35 lbs base weight
- Lightweight: 10-20 lbs
- Ultralight (UL): <10 lbs
- Super Ultralight (SUL): <5 lbs
The Big Three (60-70% of weight):
- Shelter: <2 lbs (tarp, bivy, ultralight tent)
- Sleep System: <2 lbs (quilt vs. sleeping bag, inflatable pad)
- Backpack: <1 lb (frameless, minimal padding)
Gram Counting:
- Weighing everything (toothbrush, stuff sacks, tags)
- Cutting off straps, removing packaging, shortening stakes
- Lighterpack.com spreadsheets, obsessive tracking
Gear Optimization
Shelter:
- Tarptent, Zpacks Duplex, MLD TrailStar (under 1 lb)
- Tarp + bivy combo, cowboy camping (no shelter)
Sleep:
- Quilts (Enlightened Equipment, UGQ) — no back insulation, lighter
- NeoAir Xlite pad (12 oz), closed-cell foam (Ridgerest, 5 oz)
Backpack:
- Frameless (Gossamer Gear Mariposa, Zpacks Arc Blast)
- No hip belt, minimal pockets, <30L capacity
Clothing:
- Merino wool layers, sun hoodie, puffy jacket
- Hike in same clothes daily, wash rarely
Instagram Culture (2012+)
Lighterpack Screenshots:
- Spreadsheet porn, gear lists, weight breakdowns
- Base weight flex, “$5,000 in gear” irony
Gear Shakedowns:
- r/Ultralight subreddit (400K+ members), gear advice
- “Drop the Sawyer Squeeze for Aquamira” debates
PCT/AT UL Heroes:
- Andrew Skurka (Triple Crown, Alaska-Yukon Expedition)
- Darwin (Darwin onthetrail YouTube), Jupiter (Half-Mile PCT app creator)
Controversies & Criticism
Safety Debates:
- Cutting corners dangerous? (no first aid, minimal repair kit)
- “Stupid light” vs. ultralight — reckless vs. efficient
Expense Paradox:
- Ultralight gear expensive (Zpacks Duplex $700, Arc Blast $350)
- “Ultralight = ultracostly” memes, cottage brands, DCF fabrics
Comfort Trade-Offs:
- Cold nights (quilts), sore shoulders (frameless packs)
- “Suffering for efficiency” — is it worth it?
Gatekeeping:
- r/Ultralight elitism, “not UL unless <10 lbs base weight”
- Shaming heavier packers, toxic competitiveness
