Pacific Crest Trail Quilt Guide

By topquilt.com · Updated Oct 21, 2026 · 7 min read

The Pacific Crest Trail runs roughly 2,650 miles from the Mexican border near Campo, California, to the Canadian border in Washington. Choosing a quilt for the PCT is mostly about three cold zones: the high desert mountains in spring, the High Sierra in early summer and the North Cascades in early fall. Between them, Northern California and Oregon in high summer are comparatively mild.

Unlike the humid Appalachian Trail, the PCT is mostly dry, which is good news for down. The challenge is big daily temperature swings, cold clear nights and high-elevation camps.

PCT quilt ratings by section

Southern California: the cold desert

The "desert section" covers roughly the first 700 miles to Kennedy Meadows, but it isn't all low desert. The trail crosses the Laguna Mountains, San Jacinto, the San Bernardinos and the San Gabriels, with several sections above 6,000–9,000 feet. Northbound hikers starting in April can meet frost, snow patches on high north-facing slopes and nights in the 20s at higher camps.

Lower camps on the desert floor are warmer, but dry air and clear skies let heat radiate away quickly; nights in the 40s after 85°F days are normal. Wind is a bigger issue than the number on the thermometer, so pick sheltered sites. Our desert camping quilt guide covers the radiative cooling problem in more detail.

The High Sierra: the coldest stretch for most

NOBO hikers typically enter the Sierra around mid-June. The PCT here is mostly above 9,000 feet, with Forester Pass topping out above 13,000 feet. Many hikers camp at 10,000–11,000 feet near lakes and meadows, where nights in the 20s are common and frost on the quilt shell is routine. In big snow years, hikers may enter the Sierra with snow still covering much of the high country, which means colder camps.

A 20°F quilt with a draft collar and a pad around R 4 is a solid baseline. Cold sleepers should consider 10–15°F or plan to sleep in a down jacket and hat. Camping in trees a few hundred feet below lakes and meadows is noticeably warmer and reduces condensation.

Northern California and Oregon: the warm middle

From about Sierra City through Oregon, July and August nights are often in the 40s and 50s. Some hikers swap to a 30°F or 40°F quilt here to save several ounces. Oregon is fast hiking, with lakes and forest, and nights can still dip into the 30s in volcanic high country, so a 30°F quilt is a more versatile choice than 40°F.

If you're running a single 20°F quilt, it's simple to vent: open the footbox or use it like a blanket. See open vs sewn footbox for which designs vent best.

Washington: cold, wet and late

NOBO hikers typically reach Washington in late August and September. The weather changes: more rain, fog and cloud, nights in the 30s, and the possibility of early-season snow in the North Cascades by mid-to-late September. Wet conditions plus cold make this the riskiest section for an underpowered quilt. Have your 20°F quilt back by the Bridge of the Gods if you swapped.

• Keep the quilt dry with a waterproof pack liner.
• Consider a water-resistant shell and hydrophobic down.
• Carry warm sleep clothes — a dry set of base layers is worth its weight.

One quilt vs swapping on the PCT

A 20°F quilt in 850–950 fill power from a cottage maker typically weighs roughly 18–24 oz. That's light enough that many hikers skip the swap. Check our best 20-degree quilts and best ultralight quilts for options.

Cowboy camping and condensation

The PCT is one of the best long trails for cowboy camping — sleeping in the open without a shelter. It's light and fast, but your quilt is exposed to dew and frost:

• Avoid camping next to water and meadows on clear, still nights; condensation is heavy there.
• Camp under tree cover where possible; it reduces radiative heat loss and dew.
• Let the quilt dry in the morning sun before packing, or at lunch.
• A light bivy adds warmth and keeps off dew; see quilt with a bivy.

In tents, ventilation and site selection matter; our quilt in a tent guide covers drafts and condensation.

Quilt features that matter on the PCT

Because the PCT is mostly dry and the big weight savings come from fill power, many hikers choose high fill power (850–950) down with a light 7–10 denier shell. A sewn footbox is warmer for the Sierra and Washington, but a zippered or open footbox vents better in Oregon's warm nights. A draft collar is worth its small weight penalty on a 20°F quilt. Wide models help side sleepers keep the edges sealed on chilly, breezy cowboy camps.

Pads for the PCT

Ground in the desert is warm by day but cold by dawn; ground in the Sierra is often near freezing. A pad around R 3–4.5 is typical, and a higher value is worthwhile for the Sierra and Washington. Quilts rely on the pad for all insulation underneath, so pairing matters — see sleeping pad R-value for quilts and best sleeping pads for quilts. Many PCT hikers also carry a thin foam pad for sitting and as extra insulation under an inflatable pad.

Hammocks on the PCT

Hammocks are uncommon on the PCT. The desert section and much of the High Sierra above treeline don't have reliable trees, and high camps are often in open granite. Hammocks work in much of Northern California, Oregon and Washington, but most thru-hikers carry a tent or tarp for the whole trail rather than switching systems. If you do hang for part of it, see ultralight hammock setup.

Snow years, fire closures and timing

Two variables shift PCT temperatures from year to year. In high-snow years, hikers either enter the Sierra later or deal with more snow at camp — both mean colder nights and more frost on gear. Some hikers flip around the Sierra and return later, which changes which sections they hit in which month. Wildfire closures in Northern California, Oregon and Washington can force reroutes or flips as well, so your quilt plan should be flexible enough to handle being somewhere colder than planned.

That flexibility is one more argument for carrying a 20°F quilt start to finish. If you swap, keep the warmer quilt in a bounce box that moves ahead of you, so you can recall it quickly if the plan changes.

Sleep clothes and staying warm on cold camps

On the PCT, your clothing system and your quilt work together. Most hikers carry a light down or synthetic puffy, a warm hat and a pair of dry socks reserved for sleeping. On the coldest Sierra nights, wearing the puffy inside the quilt can add roughly 5–10°F of comfort. Other habits that help:

• Eat before bed. A fatty snack helps your body produce heat overnight.
• Go to bed warm. A few minutes of movement before you lie down helps the quilt start warm.
• Keep water bottles from freezing on frosty nights by storing them upside down or inside your quilt's footbox.
• Seal the neck. A draft collar or cinched neck closure matters most at high camps.

Recommended PCT quilt specs

• Rating: 20°F for the full trail; 10–15°F for cold sleepers or early-season Sierra entries.
• Fill: 850–950 FP down for weight and packability; see fill power explained.
• Shell: Light, water-resistant fabric; around 7–10 denier is common on ultralight quilts.
• Width: Choose wide if you side sleep; drafts add up at high camps.
• Layering: A puffy jacket and warm hat extend the range; see quilt layering system.
