MSR Apparel Buying Guide: What to Wear on the Trail

Quick answer

For three-season backpacking, build a three-layer system: a moisture-wicking base layer, an insulating midlayer, and a wind- and rain-resistant shell. Choose pieces you can add or remove while hiking, and prioritize fit over features. If you want a single purchase that improves trail comfort most, start with your sleep and camp layers, then add clothing that matches the low end of your expected temperature range.

Start with your temperature range, not the label

Trail clothing works when it matches the conditions you actually expect. Before buying anything, write down the lowest overnight temperature and the highest daytime temperature for your trip. A three-season kit that handles 32°F (0°C) nights and 70°F afternoons needs different pieces than a summer kit that never drops below 50°F.

Use that range to decide how many layers you carry. If your low is near freezing, plan for a base layer, a midlayer, and a shell you can wear together. If your low is mild, one insulating layer plus a wind shell is often enough. The goal is to adjust while moving so you neither overheat on climbs nor chill on breaks.

Build the three layers in order

Base layer: choose a thin, fitted layer that moves sweat away from your skin. Avoid cotton for hiking because it holds moisture and cools you down when you stop. A synthetic or wool base layer in a light weight covers most three-season trips.

Midlayer: this is your warmth. A fleece or light synthetic jacket works for active hiking, while a puffy layer is better for camp and rest stops. If you run cold, size the midlayer so it fits under your shell without compressing the insulation.

Shell: a wind- and rain-resistant layer protects the system. Look for pit zips or a breathable fabric if you hike in humid or rainy regions. The shell should fit over your midlayer with room to move, but not so loose that it flaps in wind.

Fit guidance: how trail clothing should feel

Base layers should sit close to the skin without restricting movement. Check that you can raise your arms overhead and bend forward without the hem pulling out of your pants. If the fabric bunches under a pack strap, it will rub on long days.

Midlayers need enough room for a base layer underneath but should not be baggy. A fit that is too loose traps less warmth and can catch on branches. Puffy layers should have a little space at the shoulders and chest so the insulation stays lofted.

Shells are the exception: they should be roomy enough to wear over your midlayer and a light puffy, with sleeves that cover your wrists when you reach forward. Test the hood over a hat, and make sure the hem stays below your hip belt.

How camp gear changes what you wear

Your sleep system and camp setup affect how much clothing you need to carry. A warmer sleeping bag lets you bring a lighter midlayer, while a tent with limited ventilation may push you to choose more breathable clothing. The MSR Hubba Hubba LT 2-Person Backpacking Tent is described as light and airy with extra room for two to stretch out on luxury pads, which means you can keep camp clothing simple and focus on layers that dry quickly.

For cooking and evening camp time, a reliable stove and cook set make it easier to stay warm with a hot meal and drink. The MSR PocketRocket Deluxe Stove is described as ultralight and fully featured, and the MSR Alpine 2 Pot Set is built for two-person meals with durable stainless steel. These are not clothing items, but they support the same goal: staying comfortable at camp so you can save your insulating layers for rest stops and sleep.

What to skip and what to prioritize

Skip extra cotton shirts, heavy jeans, and multiple midlayers unless you know you run very cold. Extra weight on your back costs more energy than most people expect. Instead, prioritize a base layer you can sleep in, a midlayer that works while hiking, and a shell that handles wind and rain.

If your budget is limited, spend first on a shell and a base layer. These two pieces affect comfort in the widest range of conditions. Add a midlayer next, then upgrade camp clothing. Check the return policy and sizing before you buy, because fit is the one thing you cannot adjust on the trail.

Decision rules for buying trail clothing

• Rule 1: Match the layer to the activity: Wear a breathable base layer and a light midlayer while hiking. Save your puffy and shell for stops and camp. If you sweat through your midlayer on a climb, you will chill when you stop. Pack one active midlayer and one camp insulation layer.
• Rule 2: Buy the shell that fits over everything: Try your shell on over your base layer, midlayer, and a light puffy if you carry one. You should be able to move your arms and bend over without the hem riding up. If the shell restricts your reach, size up or choose a different cut.
• Rule 3: Choose sleep clothing you can also hike in: A clean, dry base layer for sleeping doubles as a backup hiking layer if your other layers get wet. This reduces the total number of pieces you carry. Keep sleep layers dry in a stuff sack or liner.
• Rule 4: Let your bag rating set your insulation budget: A bag rated to 32°F (0°C) like the Boost 650 covers many three-season nights. If your bag is warmer than you need, you can carry less camp clothing; if it is colder, add a midlayer. Balance bag warmth and clothing warmth so you do not carry both unnecessarily.
