Hey Guys! I am looking a short, lightweight, down sleeping bag, comfort ~-1°C. I struggle to find a sleeping bags that fits - My height is 159 cm/ 5'2".
As a fellow vertically challenged person, one had a bag made as per tjdodd's advice back in '96. Looks and works great still.. : ) Price was very similar to the prevailing big name prices. Good luck.
Have you looked at the phd range? They are excellent for compact pack size, warmth and lightness. They will make a bespoke bag from their range or manufacture one to your design. I've got a Minimus - Highly recommended.
PHD are of course excellent. another suggestion might be Cumulus. At 5'11" and 80kgs I barely fit in the one I bought for my son, but other than being a bit on the tight side the quality is top.
Both cumulus and PhD are brilliant but if you were after a more budget option I can highly recommend the forclaz trekking sleeping bag rom decathlon. Comfort of zero to -5, and a medium only weight 895 grams designed for someone upt 1.7m. I've got the long version and it's is very good.
