Sleeping Bags

A sleeping bag is the single piece of gear between you and a cold, miserable night — choosing the right one makes every other piece of kit feel better. Whether you're car camping in Connemara, backpacking across the Camino, or preparing for a winter mountaineering trip, the temperature rating, insulation type, and packable weight need to match your actual use.

Insulation: down vs synthetic

Down sleeping bags offer the best warmth-to-weight ratio and compress more tightly than any synthetic alternative. For backpacking and technical use, a quality down bag is hard to beat. The trade-off is performance when wet — down loses insulation value when damp, so pairing with a dry bag or sleeping bag liner is recommended. Synthetic bags — like Snugpak's Softie range — retain warmth even when wet, dry faster, and are generally easier to care for. For car camping, festival use, or trips where moisture exposure is higher, synthetic is often the more practical choice.

Temperature ratings

EN 13537 / ISO 23537 ratings give standardised comfort and lower limit figures. Comfort rating reflects a comfortable sleep for a relaxed adult; lower limit is the minimum a person can sleep without feeling cold. We recommend using the comfort rating for your planned conditions, adding a buffer for Ireland's genuinely cold, damp nights.

Frequently Asked Questions

A 3-season bag rated to around -5°C comfort covers most Irish camping from spring to autumn. For winter camping, particularly at altitude or exposed locations, a bag rated to -10°C or lower is strongly recommended. Ireland's cold is damp (and nice and windy!), which makes it feel colder than the thermometer suggests. If you are planning on a summer outing - you could get away with something a lot more lenient on temperature like a 5c bag.

Mummy bags are tapered to reduce dead air space, keeping you warmer with less weight. Rectangular bags offer more room to move but are heavier and less thermally efficient. For backpacking and anything above car camping, a mummy is the sensible choice - less weight, less bulk to carry.

Never store a sleeping bag compressed in its stuff sack long-term. Keep it loosely stored in a large cotton or mesh storage bag to preserve the loft of the insulation. Both down and synthetic bags benefit from a cool, dry storage environment. Some of our premium sleeping bags from brands like Rab or Sea to Summit come with both a stuff sack and their storage bag, which is a nice touch!
