too cold to continue for 3 seasons

Halfway through the night and with thermal clothing on and the highest R number on the insulation mat, at NL temperatures, I wake up with a cold back. Am a side sleeper. I think this sleeping bag is suitable for summer night temperatures

Best bit of decathlon kit I have.

Very cozy and lightweight sleeping bag. Took round Scotland for 5 days. Temps were in the 6° range most nights and with my sleeping mat and jumper, I was still cozy. At this price point its great and only 1kg. It packs down relatively small also. My GF has even been using it round the house.

What is the temperature rating?

All our sleeping bags display the temperature ratings, tested by an independent laboratory (AITEX), in accordance with the European standard NF ISO 23537 - 1:2022. The comfort temperature rating is the lower limit at which the user in relaxed posture is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use). Choose your sleeping bag according to this criterion.

What is the temperature rating (lower limit at which you feel comfortable)?

The comfort limit temperature is the temperature limit at which a person curled up in the sleeping bag is in general thermal equilibrium, neither too cold nor too hot (determined for a man in normal conditions of use).We recommend using an insulation mattress to optimise your thermal comfort.

An important clarification concerning the iso 23537-1 standard

In the context of this standard, the measurement protocol of a sleeping bag’s thermal protection uses a mattress with thermal resistance equal to an R-value of 4.8.This means that by using a less insulating mattress, the thermal performance of your sleeping bag will be lower.We therefore recommend you use an insulating mattress to optimise your thermal comfort.

Some advice to consider before you get into your bag

Dress simply (1 layer of clothing is enough). Warm-up your extremities: hats, gloves, socks, hand/feet warmers, rubdowns, etc. A flask of hot water can be used as a hot water bottle (as long as there's no chance of it accidentally opening!) Contract your muscles (70% of the energy consumed is converted into heat) but do it without moving as this could create a draught. Use a bag liner to optimise warmth and avoid washing your sleeping bag too frequently.

Style
