Sintetic and down

The thermal efficiency of down for the coldest conditions 

When backpack weight and freezing temperatures are the deciding factors, down sleeping bags are the ultimate choice. Thanks to the extraordinary insulating properties of goose or duck down, these models offer an unbeatable warmth-to-weight ratio and high compressibility, taking up minimal space in your gear. They are the ideal companions for mountaineering, multi-day high-altitude treks, and winter bivouacs where every single gram saved counts.

The versatility and durability of synthetic insulation in any environment 

Synthetic sleeping bags, on the other hand, are the optimal solution for those tackling humid climates or trips where getting damp is a constant risk. Synthetic fibres retain most of their insulating properties even when wet, dry very quickly, and are extremely easy to wash and maintain over time. At Alternativa Sport, we offer a carefully selected range of both technologies from top outdoor brands to ensure warm, restorative, and safe nights under the stars.
