Base Layer Collection — X-Boundaries Singapore
Your First Layer. Your Most Important One.
The right base layer makes all the difference — regulating your body temperature, wicking sweat away from your skin, and keeping you comfortable through every mile. At X-Boundaries, we carry the best in class base layers from two of the world's most trusted outdoor brands: Montbell and icebreaker.
Montbell ZEO-LINE base layers are engineered with Japan's precision and Light & Fast® philosophy — ultra-breathable, quick-drying, and designed to perform in high-humidity and variable conditions. icebreaker Merino base layers harness the natural power of New Zealand Merino wool — softly temperature-regulating, naturally odour-resistant, and gentle enough to wear all day, every day.
Whether you're layering up for a mountain trek, a winter trip, or an active commute, we have the right weight for your conditions:
- 150–170 gsm Ultralight — All-season versatility for warm to mild conditions
- 200–230 gsm Lightweight — Ideal for moderate to cool temperatures
- 260–280 gsm Midweight — Best suited for cold conditions and layering
- 320–380 gsm Heavyweight — Maximum warmth for the coldest environments
Shop base layers at X-Boundaries — available online and at our store in Mandarin Gallery, Orchard Road, Singapore.
