Spring and autumn transform the mountains and outdoor environments into unpredictable terrain: cold mornings, warm afternoons, brief but intense showers, variable winds, residual ground moisture, and temperature swings of 5 to 20 °C within hours. Equipping yourself for the shoulder seasons requires a system that adapts to these changes while remaining lightweight, breathable, protective, and versatile. This is exactly the purpose behind the AYAQ wardrobe.
1. Technical challenges of the shoulder seasons
Shoulder seasons are not just “mini winters” or “mini summers”: they present unique challenges.
- Wide temperature range: cold mornings, warm midday, damp cold evenings.
- Ambient humidity: dew, showers, fog, melting snow at altitude.
- Variable wind: causing unpredictable convective cooling.
- Variable effort levels: frequent shifts between active climbing and slower walking.
The clothing system must allow rapid adjustment without moisture buildup.
2. Base layers: the key role of RWS merino wool
Merino wool is essential for managing sudden temperature changes. Warm even when damp, breathable, and regulating, it perfectly supports shifting activity levels.
- BIAFO (men / women): 100% lightweight merino, ideal for days with sustained morning effort.
- MEFONNA (men / women): 100% versatile merino, well suited for irregular activity rhythms.
- SHIRWALI (men / women): merino blended with Tencel (~240 g), perfect for cold mornings with increasing wind during the day.
Goal: maintain stable temperature without overheating.
3. Midlayers: adjusting warmth without trapping moisture
KOKANEE (men / women)
Active fleece, ideal for cool mornings, dynamic climbs, and humid days. Its vapor management makes it a pivotal layer for shoulder seasons.
AROLLA (men / women)
Brushed fleece, warmer. Best for variable but generally cool weather or frequent stops.
4. Outer layer: the key to shoulder season versatility
AYAQ hardshells — SKORA (men / women), LONAK (men / women), LONAK-XT (men / women) — feature the same exceptional non-microporous hydrophilic membrane: 52,000 Schmerbers, RET < 12, highly windproof, ultralight, non-clogging, PFC-free.
- SKORA (men / women): lightest and most streamlined, ideal for sudden showers and rapid weather changes.
- LONAK (men / women): more enveloping with raglan sleeves, design inspired by Inuit traditions. Perfect for damp cold conditions.
- LONAK-XT (men / women): fully equipped version for technical terrain and long outings with unstable weather.
In shoulder seasons, these hardshells are often the core tool: carried in the pack, worn at summits, used in strong winds, or simply to block unexpected showers.
5. Lightweight alternative: SHANDAR windbreaker (men / women)
SHANDAR (men / women) embodies the “shoulder season” philosophy: ultra-light, highly breathable, immediate wind protection. Ideal for:
- cool mornings,
- active climbs,
- short outings with uncertain weather,
- days with low rain risk but frequent wind.
A highly responsive tool.
6. Softshells and hybrids: comfort and versatility
RIMO (men / women)
Softshell with windproof membrane at the front and highly breathable fabric at the back. Perfect for spring ski touring, dynamic hiking, or outings with fluctuating cold and mild weather.
RAVEN (men / women)
Asymmetric softshell: windproof membrane on the chest, extreme breathability on the back. Very effective when effort alternates between intense phases and short breaks.
7. Pants for the shoulder seasons
- CLIFTON: technical membrane pants, highly windproof, excellent for cool days or exposed ridges.
- RIMO (men / women): dynamic option for active effort, breathable and protective.
- NUNATAK (men / women): for wet shoulder seasons with regular rain or melting snow.
Bottom layers must adapt to temperature changes as much as tops.
8. Recommended combinations for shoulder seasons
- Cold morning, mild day: MEFONNA (men / women) + KOKANEE (men / women) + SHANDAR (men / women).
- Irregular showers: BIAFO (men / women) + KOKANEE (men / women) + SKORA (men / women).
- Intermittent cold wind: SHIRWALI (men / women) + AROLLA (men / women) + LONAK (men / women).
- Long outings with uncertain weather: MEFONNA (men / women) + KOKANEE (men / women) + LONAK-XT (men / women).

Conclusion
The shoulder season is a time of contrasts: warmth, cold, wind, humidity, quick clearings. The AYAQ wardrobe provides a coherent system to absorb these variations without sacrificing comfort or performance. Thanks to its 52,000 Schmerbers hardshells, SHANDAR windbreaker (men / women), active fleece jackets, and RWS merino base layers, the shoulder season becomes a terrain of controlled adaptation, not a constraint.
