Patagonia R1 Fleece Hoody Review

Overview

The R1 Fleece Hoody is the fleece that climbers, ski tourers and trail runners have been wearing for years. It uses Polartec Power Grid in a close-fitting, balaclava-hooded pullover. It’s built for people who generate heat and want to shed it quickly. The trade-off is that it’s a layer for moving, not for standing around in a cold wind.

Performance

Warmth and breathability. The grid pattern is the whole idea. Dense fleece “ridges” hold warmth against the body, and the channels between them let moisture and heat escape. Outdoor Gear Lab’s testers found it works best when active. They wore it on pre-sunrise runs, evening climbs and brisk late-afternoon hikes, and they reached for a heavier layer once they stopped moving or the temperature dropped further. A long-term owner review at Better Trail reached the same conclusion. After more than a decade of use, that reviewer puts the sweet spot below 20°F during fast, high-output efforts such as trail running or alpine climbing. In those conditions it stays warm without overheating.

It is not the most breathable fleece available. Better Trail notes it runs warmer and less breathable than newer, thinner grid fleeces. On steady uphill grinds in mild weather, thru-hikers will find the R1 hotter than a lightweight fleece. Its better use is as the layer pulled on during the cold start of the day and stowed once the climb warms up.

The hood. The snug balaclava-style hood is the feature reviewers praise most. Outdoor Gear Lab named the fitted hood and long front zip among its favorite details. The hood fits under a shell hood and, in tests of the related women’s model, also fit under or over a climbing helmet. The 3.8-oz fabric in the hood and side panels is lighter than the 6.9-oz body, which keeps the hood from feeling bulky and adds ventilation along the ribs. Backpackers.com reviewers also point to thumb holes and an extended hem, which help seal gaps at the wrists and waist. With the zipper fully up, the hood brings noticeably more warmth than a conventional collar.

Weather resistance. Weather resistance is the R1’s main weakness. Outdoor Gear Lab scored the women’s version 3 out of 10 for weather resistance, and its tester verdict on the men’s model called weather resistance poor. Wind goes straight through the open grid, and any rain soaks in. The R1 is meant to be worn under a shell, not instead of one. Hikers who want a fleece that tolerates breeze and drizzle by itself will find that Patagonia’s TechFace and CrossStrata versions suit that job better, though OGL’s testers found the TechFace too stiff and bulky to work as a midlayer.

Fit and layering. The cut is athletic and slim. That makes it easy to layer under a hardshell or insulated jacket and keeps bulk down under a pack’s shoulder straps. The spandex content gives it plenty of stretch for scrambling or climbing, and the hem tucks neatly under a harness or hip belt. Tall or broad-shouldered hikers who want to wear it over a puffy should size with care.

Durability. This is a long-lived garment. A reviewer who bought an earlier R1 Pullover Hoody in 2014 was still using it more than a decade later and called it a true workhorse midlayer. The Polartec grid is also quick to dry and resists odor, which suits multi-day trips without laundry.

Pros & Cons

Pros

• Excellent warmth-to-weight at 332 g
• Grid fleece vents heat and sweat well during sustained effort
• Fitted balaclava hood fits under shells and helmets
• Stretchy, slim cut layers cleanly under a shell or puffy
• Long service life, with owners reporting a decade or more of use
• Chest pocket and deep front zipper for venting

Cons

• Little wind or rain resistance
• Not warm enough as a standalone layer for static stops in cold weather
• Can run warm on hard climbs in mild temperatures
• Single chest pocket; no hand pockets
• Slim cut leaves little room for bulky layers underneath

Who Should Buy This

The R1 Fleece Hoody suits three-season hikers, shoulder-season and winter backpackers, ski tourers and climbers who want one active midlayer for cold starts and high-output days. It pairs well with a lightweight wind shirt or rain shell, which together cover most conditions. Hikers who spend most of their time in camp or other low-output situations should look at a puffy instead, since the R1 won’t keep them warm sitting still. Warm-weather hikers who want something lighter and more ventilated will do better with a thinner grid fleece, and anyone wanting a standalone outer layer needs something with a wind-resistant face.

Verdict

The R1 Fleece Hoody does one job exceptionally well: it regulates temperature for people who are moving in the cold. The hood, stretch and durability justify its reputation, even if wind protection and static warmth are weak. Buy it as an active midlayer worn under a shell and it will rarely let you down.
