Bikepacking differs from classic cycle touring in how gear is carried. Instead of large racks and panniers, cyclists opt for a set of compact bags distributed around the bike frame. With luggage volume limited, every piece of equipment must take up as little space as possible, be as light as possible, and serve multiple functions.
This is why clothing and equipment choices in bikepacking are based on the three-layer principle: a base layer to wick away moisture, an insulating layer to retain warmth, and an outer layer to protect against wind and weather. When the weather changes, simply adding or removing a layer quickly adapts your outfit to new conditions.
This approach is particularly effective for multi-day bikepacking trips. It allows for a compact setup that takes up little space in bags, remains comfortable while riding and during breaks, and avoids carrying too many clothes for a bike trip.
In this article, Routes and Roads experts explain how the three-layer system works, what clothing to prioritize for bikepacking and gravel travel, and how to combine different layers according to route conditions.

Advantages of the three-layer system
For a road training ride or a cycling race, clothing is generally chosen based on distance, effort intensity, and weather forecasts. Priority criteria are then maximum ventilation, aerodynamics, light weight, and great freedom of movement. Clothing versatility plays a secondary role, as it's possible to change immediately after arrival.
In bikepacking and multi-day bike tours, the needs are different. A single outfit accompanies the cyclist throughout the adventure: during pedaling phases, long descents, breaks, and evenings at the campsite.
Bikepacking gear is carried in compact bike bags
Equipment must dry quickly, take up minimal space in bags, be easily combined with other clothing, and adapt to weather changes without requiring additional items. This is precisely the role of the three-layer system.
Each layer fulfills its specific function. The first wicks away moisture, the second retains warmth, and the third protects against wind and weather. By combining them, it's possible to create an outfit suitable for gravel, bikepacking, and long touring rides in varied weather conditions, without overloading the bike.
The three-layer rule applies to the entire body. Only the clothing changes: cycling jersey, thermal underwear, bib shorts, cycling tights, insulating clothing, cycling vests, windbreakers, shell jackets, and, if necessary, shell pants. Thanks to this approach, it's possible to travel with few clothes even on multi-day trips.
Bikepacking base layer
The base layer is worn directly against the skin. It wicks away moisture and maintains a comfortable climate during activity. The more effectively this first layer performs its role, the better subsequent layers can function.
For the upper body, the base layer can be a cycling jersey, lightweight thermal underwear, or a snug-fitting long-sleeve synthetic T-shirt. In summer, most cyclists prefer a jersey worn directly on the skin. For mid-season trips, in cool weather, or on mountainous routes, a thin thermal base layer worn under a jersey or long-sleeve cycling top will be more suitable.
The base layer wicks away moisture and keeps the skin dry during effort
The same principle applies to the lower body. In warm weather, the base layer typically consists of cycling shorts or cycling bib shorts with a chamois pad, designed for long hours of pedaling. When temperatures drop, these are replaced by long cycling tights or a warmer model, which maintains freedom of movement and comfort during long days in the saddle.
For most bikepacking and gravel routes, models made from modern synthetic fibers are the most suitable. They quickly wick away moisture, dry fast, and take up very little space in bags.
For long adventures, cool climates, and routes where clothing needs to be worn for several days in a row, base layers containing merino wool are well-suited. This material has thermoregulating and antibacterial properties, allowing clothing to stay fresh longer, even when washing opportunities are limited.
Bikepacking insulating layer
The insulating layer is used in cool, cold, and dry weather. Its role is to retain heat during pedaling phases, breaks, and evenings at the campsite.
For the upper body, a medium-weight thermal base layer, a fleece, or a lightweight insulating jacket is chosen. The choice depends on the temperature, duration, and conditions of the route. In cool weather, a thin thermal base layer or fleece is usually sufficient.
A lightweight insulated jacket is ideal for breaks and evenings at the campsite
If the route crosses French mountainous regions, such as the Alps, Jura, or Massif Central, where mornings and long descents can remain cold even in summer, a compact insulated jacket will be particularly useful.
For the lower body, additional insulation can be provided by warm cycling tights, which replace short bib shorts when temperatures drop. When mornings are cool but temperatures rise during the day, leg warmers are a very practical solution. They can be quickly removed during a break and stored in a bag without having to completely change outfits.
When choosing an insulated jacket, consider its filling. Synthetic insulation is more resistant to moisture and retains its thermal properties even when wet. Down offers a better weight-to-warmth ratio and a smaller volume when compressed, but it requires more care and withstands prolonged exposure to moisture less well. For most bikepacking, gravel, and long cycling trips, a synthetic jacket is therefore often the most practical choice.
The insulating layer spends a large part of the day in a bag. Compactness therefore becomes an essential criterion when choosing this garment for bikepacking. Consider its weight, its packed volume, and its ability to quickly regain its shape after compression.
Shell clothing protects against rain and strong wind
Bikepacking protective layer
The protective layer is used in windy or rainy weather. It limits heat loss, protects against the elements, and allows other layers to retain their properties.
For the upper body, it includes cycling vests, windbreakers, and shell jackets.
A compact vest is particularly suitable for cool temperatures, long descents, and headwinds. A windbreaker offers additional protection during long cycling days. For multi-day bikepacking, a shell jacket should be part of the basic equipment, regardless of the forecast. Conditions can change in a few hours, and prolonged rain can lead to significant cooling and considerably reduce comfort for the rest of the trip. Modern shell clothing is compact and has little influence on the total weight of the gear.
For the lower body, shell cycling pants or overpants are used. They are worn over bib shorts or cycling tights in case of heavy rain, wind, or a sudden drop in temperature. Thanks to long side zippers, they can be put on quickly without removing cycling shoes. Once folded, shell pants take up very little space in a bag and are perfectly suited for self-supported routes.
Several elements should be considered: the cycling-specific cut, back length, ventilation zones, and the ability to wear the garment over other layers. The jacket should cover the lower back in a cycling position while allowing complete freedom of movement during pedaling. For shell pants, prioritize an anatomical cut, durable reinforcements in areas of contact with the bike, and a design that allows them to be put on quickly directly on the route.

Essential bikepacking accessories
Well-chosen bike accessories allow you to adapt your equipment more precisely to weather conditions and change less often. Despite their light weight, they significantly improve comfort during long bike trips. This is why experienced bikepackers and gravel riders almost always include them in their basic gear.
To protect the head, a lightweight cycling cap, helmet liner, or a multifunctional Buff neck gaiter is used. This accessory remains one of the most versatile: it can be worn as a neck gaiter, headband, light head protection, or face protection against the wind. In summer, it helps protect against sun and dust, while in cool weather it limits heat loss around the neck and face.
Cycling gloves are chosen according to the season and route conditions. Lightweight summer models improve grip on the handlebars, reduce vibrations, and protect hands in case of a fall. In cool weather, long gloves are more suitable. For multi-day trips, it is also advisable to bring a dry spare pair.
Arm warmers and leg warmers are also very practical. They are easily worn in the morning when temperatures are low, then removed and stored in a bag when the air warms up.
Don't forget cycling socks either. In summer, thin models made of synthetic fibers are perfect, while for cooler temperatures and long adventures, socks containing merino wool are more suitable.
