Assos sJ.blitzFeder Shell


We love this jacket for many reasons. It is a sharp looking garment with several different materials on different patterns with different textures. The blending of all of these patterns and materials give the iJ.haBu5 a unique and tactile feel that oozes of style and class. Technically, it is astounding due to its versatility. We find that it is a good choice for the sweet spot of winter cycling: low 40's to mid 50's temperatures. Perhaps what is most intriguing about the jacket is its weight, or lack thereof. Assos has managed to offer a piece that is comfortable in this temperature range and keep it on the thin side in terms of material. By selecting a clever choice of in-house designed fabrics and materials, there simply is no bulk. Or as Assos succinctly states it, more performance, less fabric volume.

A majority of the jacket has RXQ material, which is essentially a compressed/waffled wicking fleece. It is warm and super soft against your skin. RXQ is nearly impossible to beat for warmth vs. volume of material used. Thermal material is not enough to complete a proper winter jacket, so the entire front and arms of the jacket have Assos stratagonLight for windproofing and cold air mitigation. Unlike most windproofing fabrics, stratagonLight is actually elastic and has all way stretch characteristics which makes for a snug but comfortable fit. Add these two features together and that is when the magic happens. The interior sports finely woven mesh micro fibers that enhance wicking and moisture movement. Storage is taken care of by 3 rear pockets. Two zippered with an open pouch sandwiched in between. For all of those riders who cannot be without music or a form of communication, a handy iPhone sleeve pouch was included.

To summarize the iJ.haBu we would say it is a full on winter jacket that is about the weight of a heavy long sleeve jersey and performs in a variety of temperatures. With proper care this jacket will provide many seasons of joy.

    Wow, finally got to use my Xmas present. An amazing emergency jacket, it is a great piece of clothing from the best manufacturer of cycling gear. It rolls up small and is so light. This is a must have...

    Typical of Assos, this jacket is simply amazing. It is lightweight, yet on a cold damp ride I was warm and dry with only a simple baselayer underneath (polartech). On a cold day you can stay warm (jersey and arm warmers work great underneath), then when it starts to warm up, you can unzip until you are ready to take it off; it is thin and light and stuffs nicely into the jersey pocked. You look at it and think that it could not possibly keep you warm, but it does. If you think this jacket is pricey and are not sure, just buy it; it is great in so many conditions, making it extremely versatile. I have Assos gear that is 10 years old, and it is like new. There is no other make I have tried that comes even close to Assos, and the haBu is one of my favourites. When you first put it on, it will seem small at the front, but when you get into riding position, it fits perfectly - it is designed with your bike position in mind. An awesome jacket.
