Integral Designs Rundle Jacket SPOTLITE REVIEW Review

Hoodless, synthetic insulated jacket with an optimum balance of warmth, durability, wind/water resistance, and light weight.

Recommended

Overall Rating: Recommended

The ID Rundle Jacket's 4 ounce/yd2 Primaloft Sport gives it more insulation than many synthetic insulated jackets on the market. Its thicker insulation plus a Pertex Microlight shell are a good balance of durability, warmth, wind resistance, and water resistance. Some weight savings could be attained by going to 20 denier fabrics, but the tradeoffs would be less durability and wind/water resistance. Overall, the Rundle is well-designed and a good choice where more warmth is needed.

Overview

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.

At 16.6 ounces (measured weight, size Large), the Rundle Jacket is on the heavy side for ultralight backpacking, but it's a highly versatile piece for cold weather snow sports and winter camping. Specifically, I wore the Rundle either as an outer layer or midlayer for casual wear, winter hiking, snowshoeing, backcountry skiing, and winter camping.

The Rundle Jacket has a total of three zippered pockets - two hand pockets plus this zippered pocket on the inside. I found all three pockets very handy for securely stashing small items and keeping them from freezing. Photo by Bill Webbe.

When worn as an outer layer over one or two baselayers, I found the Rundle to be a remarkably warm jacket for active pursuits in cold weather. Its Pertex Microlight shell is a good balance of durability and wind/water resistance. The downside of Microlight is that it is less breathable, but breathability is inversely related to wind and water resistance and the latter factors are more important for a shell fabric on an insulated jacket.

I chose the ID Rundle Jacket as part of my layering system for an eleven-day winter camping trip in Yellowstone National Park. On that trip, where temperatures ranged from -16 to 40 °F, I mainly wore the Rundle Jacket as a midlayer. I wore one or two wool base layers under it and a lightweight down jacket or shell jacket (Montbell Thunderhead Jacket) over it, as needed to maintain my comfort level. When actively skiing or hiking in temperatures down to 0 °F, I usually wore a wool base layer, the Rundle Jacket, and a shell jacket, with excellent results. Opening the front zippers of the jackets gave me a lot of temperature adjustment.

My cold temperature layering system consisted of two wool base layers, ID Rundle Jacket, and Montbell Alpine Light Hooded Down Jacket.

The Rundle has smooth fabrics on both the outside and inside, making it easy to pull it on over other clothing, or don other clothing over it. Its thumb loops are also a great aid for putting it on.

Pros and cons. The Rundle's Lycra bound cuffs and thumb loops (left) are simple and functional. However, the small zipper pulls on the hand pockets (right) are an annoyance; they are hard to grasp with or without gloves. I added some cord loops to them.

Overall, the Integral Designs Rundle Jacket is an excellent choice for cold weather pursuits, and it can be worn as a mid- or outer layer in a wide variety of clothing systems. It's not necessarily a good choice for ultralight summer backpacking, where a thinner synthetic jacket like the Bozeman Mountain Works Cocoon Pullover (9 ounces, size Large) is sufficient. The Cocoon's 1.8 oz/yd2 Polarguard® Delta insulation is less than half the weight of the Rundle's four-ounce Primaloft Sport. More insulation means more warmth, and the Rundle is a good choice when more warmth is needed.

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.

Repeated compression resistance?? on 07/03/2008 11:09:45 MDT Print View

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.

Eric
