Shopper : Why Did You Choose This?BRIAN G : I've had a few Rab jackets and they are perhaps the best brand out there. They are extremely well designed with only the best materials and construction quality. They are well built and durable. The Rab Positron Pro is very well insulated with an excellent shell and should perform well in very cold weather. A great jacket for cold mountain weather.

Nice Jacket, Fast Shipping

Sunnysporta delivered on fast shipping and an excellent sale price. This is a quality jacket that fills the niche of having high fill weight and high fill power. Should work great for mountaineering trips in the PNW while taking breaks at or near the summit. Medium fits well for my size: 5'11", 170 lbs, 32 in waist.

Thumbs up!

The jacket is top notch. At a nice sale price, I settled for the gray, a bit color drab compared to red or warm blue. Regardless, the jacket is puffy, warm, sturdy, well-fitted, and well designed. Height 70 inches weight 150 pounds chest 41 inches; size small fit fine with a T-shirt and hoody layer. Highly recommend. And, Sunny Sports was super fast in fulfilling the order and free shipping arrived on the expected arrival date. Thumbs up!

Awesome mountaineering jacket

The right mix of warmth, features, low weight that I was looking for. Love the ease of adjustment on the cuffs and hood. I normally wear Medium and the medium here fits me great, with room for layering underneath.

Whether you're heading for the heights of the Himalaya or planning a polar expedition, the Positron Pro is a down-filled jacket with zoned construction to optimise warmth and mobility while minimising bulk, so you can endure prolonged exposure to very cold conditions.

Designed for mountain and expedition use up to 6000m, the Positron Pro Jacket uses a Pertex Quantum Pro shell to provide protection from the weather, and is filled with the highest quality 800 fill power ethically-sourced down. Box-wall construction on the torso, hood and upper of arms provides extra insulation on more exposed areas, while stitch-through construction on the underarms and side panels allows increased mobility while reducing bulk, weight, and packsize.

A two-way front zip with synthetic insulated baffle behind provides maximum warmth, and helmet compatible down filled hood has wired peak and face baffle. Concealed hood adjusters are easy to use with gloved hands. The Positron Pro is optimised to offer the perfect balance of mobility, comfort, and protection in very cold conditions.
