Frogg Toggs Ultra-Lite2 Rain Jacket Review

Overview

The Frogg Toggs Ultra-Lite2 is a 2-layer, non-woven polypropylene rain jacket that has ridden in thru-hikers’ packs for years on one selling point: it keeps rain off for about the price of a trail-town dinner. It weighs 160 g in the lighter version and packs to roughly the size of a pair of balled-up socks. The trade-off is that the fabric tears, the seams fail, and nobody who owns one treats it as a long-term piece of gear.

Performance

Weather protection. The jacket does what a rain shell is supposed to do. Owners report staying dry through multi-hour storms, including a four-hour offshore squall and long wet days on trail. One hiker credited the jacket with getting them through hail and freezing rain on a 12,000-foot exposed ridge, noting that it kept them surprisingly warm. The non-woven fabric also works as a wind block, and the large hood fits over a hat and stays put. Water beads and sits on the surface rather than draining, a quirk one owner flagged, but the layer underneath stays dry.

Breathability. Frogg Toggs markets the fabric as breathable, and it does move vapor better than a coated nylon poncho-shell would at this weight. It has limits. There are no pit zips, the cuffs can’t be opened up, and the front zipper is the only vent. Climbing in warm rain, wearers get damp from the inside. The jacket suits a steady walking pace in cool, wet weather and stationary use around camp better than a sweaty ascent.

Durability. This is where the Ultra-Lite2 loses points. Backpacking Light forum veterans describe the construction as fragile and call the jacket disposable by design. Because the seams are welded instead of stitched, a tear or a pulled seam is the failure that lets water through. Reviewers on Trailspace describe leaking seams after days of rain and shredded pant legs on the matching suit. The jacket usually fares better than the pants, since it avoids foot traffic, but brush, pack straps and snagged branches take a toll. Some owners do get long service. One buyer replaced a suit after more than a decade of occasional use, and a PCT hiker called the jacket sturdy enough for multi-week trips. These are the exceptions, and the hiker was describing a shell kept for rain, not worn daily.

Packability and handling. The fabric is soft, quiet by the standards of cheap plastic shells, though still crinkly, and it compresses into the included stuff sack without complaint. The cut is roomy and made to go over insulation. A snug fit is claimed for the women’s version. There are no pockets, which one owner who wears it all day on a delivery route called the one thing missing.

A note on the certification. ASTM F1670 is a protective-clothing standard for resistance to synthetic blood penetration. It shows the material blocks liquid, but it is not an outdoor rain rating and does not predict how the jacket will hold up on trail.

Choosing a Version

The two versions are the 160 g Standard and the 249 g Medium, a gap of 89 g (about 3 oz). For context, published weights for the Ultra-Lite2 jacket range from 5.5 oz (156 g) for a men’s small to 8.8 oz (249 g) for a men’s extra-large, so weight climbs with the amount of fabric in the cut. Frogg Toggs lists the women’s jacket at 6.4 oz (181 g).

Hikers counting grams should take the 160 g Standard, which carries almost no penalty over a poncho. The 249 g Medium costs the weight of a small snack bag and makes sense for anyone who wants extra room to layer a puffy underneath or to move their arms freely. Neither version adds pockets, vents or other features, so the choice comes down to fit and weight.

Pros & Cons

Pros

• 160 g in the lighter version, with a stuff sack included
• Price around $20–28, so it can be replaced mid-hike without regret
• Waterproof and wind-resistant in sustained rain, by owner accounts
• Large adjustable hood fits over a hat
• Packs to roughly the size of balled-up socks
• Fabric breathes better than a plain plastic shell

Cons

• Tears and seam failures are common, especially under pack straps and in brush
• Welded seams leak once they pull apart
• No pit zips, adjustable cuffs or pockets
• Gets clammy on climbs in warm weather
• The one-year warranty covers manufacturing defects, not wear
• Looks like a trash bag in the photos

Who Should Buy This

The Ultra-Lite2 fits the hiker who needs a rain layer for a summer section hike, a shoulder-season trip with a forecast that’s mostly dry, or an emergency shell kept at the bottom of the pack on every trip. It’s also a sensible choice for a thru-hiker who budgets for replacing it every few hundred miles. Anyone heading into weeks of persistent rain, heavy bushwhacking, or technical terrain should buy a sewn-and-taped nylon shell with real vents, and so should anyone who expects one jacket to last several seasons.

Verdict

The Ultra-Lite2 is the cheapest credible way to carry a rain jacket under 250 g, and it works when used gently. Treat it as a consumable and the value is hard to beat; expect it to behave like a $200 shell and it will let you down.
