I first got the Roma 300 SE sleeping bag in Summer 2022 and… I love it! It is such a soft and cozy sleeping bag with it’s Suresoft brushed polyester lining, unlike other bags that have a slippery material and feel cool to the touch. I get cold easily, even during summer, so this bag really helped to keep me warm during the cool nights, and during the warmer nights I didn’t have to wear so many layers. I’m 5′ 2″ tall, so the short tapered shape of this bag was perfect for me…I had enough space to sleep comfortably. I love the bright seafoam colour of the bag too. So colourful and fun! I will definitely be continuing to take this sleeping bag with me on future camping adventures!

I recently used your Roma 300 bag on a trek to Torres del Paine and Fitzroy. It worked out fine and was very comfortable to sleep in. My Chilean guide was very happy to get it as a gift at the end of the hike. Great performance at little weight for a good price and Canadian! I’m now a loyal fan of Hotcore sleeping bags.

Critical Layer Construction
We use thermal body-mapping construction to place the insulation where it will do the most good. You already have an insulating sleeping mat below you, and most of the sleeping bag insulation that is below will be compressed by your body weight, making it inefficient. We move much of this insulation to the top of our sleeping bags where it will trap warmth from your body.

Then we add an extra layer of TrueLoft™ insulation in the core body area, from the neckline to below the beltline, to help achieve and maintain the temperature ratings. This extra layer of insulation will trap more warmth from the body than comparable sleeping bags, while adding very little to the weight, size, and cost of the sleeping bag. Think of it as putting on a jacket, the first thing we all do when we need to stay warm.

We call this Critical Layer Construction.

High quality TrueLoft™ micro fibre synthetic insulation traps more warm air between its fibers than traditional insulations with the same loft. This gives you a warm, soft sleeping bag in a compact and lightweight size.

  • Lightweight – some of the lightest weight insulation available
  • Compressible – siliconized fibres slide easily allowing for greater loft, compressibility, and softness
  • Breathable – insulation and fabrics breathe to allow heat-robbing moisture & humidity to escape
  • Extremely quick drying – hydrophobic qualities allow TrueLoft™ to absorb less water and dry quickly
  • Warm when wet – while drying, TrueLoft™ still keeps you warm, performing better than inferior insulations
