The Integral Designs Rundle jacket is a hoodless synthetic insulated jacket. Insulation is 4 oz/yd2 Primaloft Sport, which is thicker than many lightweight synthetic insulated jackets. More insulation means more warmth, but also means a little more weight. Its outer shell is 30 denier Pertex Microlight, which at 1.4 oz/yd2 is a bit heavier than popular 20 denier Pertex Quantum at 0.9 oz/yd2, but it's also more durable, windproof, and water-repellent.

Integral Designs Rundle Jacket SPOTLITE REVIEW Review
I expect a bit more from BPL reviews. How well did it perform in the field? This was not as in depth as most BPL content.
Its a spotlite review, not a normal article or review. Spotlite reviews are generally brief and less in-depth than regular articles.
Thanks, Good to know
Will,
How does PrimaLoft "Sport" do for repeated compressions in a stuff sack? I think it's PrimaLoft's latest iteration.
I have a similar British military inner jacket made with Thermoloft Micro insulation & Pertex which does very well after many compressions.
I ask because my 10 year old Caribou Mountaineering summer sleeping bag with the original PrimaLoft lost virtually ALL its loft after 3 summers, making me very leery of using PrimaLoft again.
