The picks, ranked
Outdoor Research Helium
Outdoor Research
Why it's here: At 0.18 kg it's the lightest that still does the job.
The Outdoor Research Helium is the ultralight rain-jacket benchmark for 3-season backpacking. At 6.3 ounces of Pertex Diamond Fuse 2.5L fabric, it weighs less than a granola bar and packs into its own chest pocket. The Diamond Fuse face is unusually abrasion-resistant for an ultralight shell, which is the Helium's real edge over comparable Marmot, REI, and Patagonia options at this weight. It is not a hardshell — sustained 6-hour storms will eventually wet out the fabric, but for typical 3-season trips with intermittent rain, it delivers exactly what backpackers need at this price point.
Patagonia Nano Puff
Patagonia
Why it's here: At 0.36 kg it's the lightest that still does the job.
The Patagonia Nano Puff remains one of the most versatile synthetic insulated jackets available. Its PrimaLoft Gold Eco insulation, featherweight packability, and do-everything design make it an essential layering piece for hikers, climbers, and everyday adventurers.
Salomon X Ultra 4 Mid GTX
Salomon
Why it's here: At 0.79 kg it's the lightest that still does the job.
The Salomon X Ultra 4 Mid GTX is one of the best all-around hiking boots for day hikers and weekend backpackers. Its Contagrip MA outsole delivers exceptional traction, GORE-TEX waterproofing keeps feet dry, and the lightweight build reduces fatigue on long days. A near-perfect mid-cut option for mixed terrain.

Frequently asked questions
Is ultralight rain gear actually waterproof?
The best ultralight shells are genuinely waterproof for typical 3-season rain, but they wet out faster in sustained storms and the lighter fabrics abrade quicker. For most trips that trade-off is worth the weight saving.
