Mammut Jungfrau Longsleeve Review
Mammut’s Jungfrau Longsleeve is so functional that it cannot be constrained to a single season of use. I have been testing the Jungfrau through the summer and into the fall months and have found it to be an incredibly versatile top. The Jungfrau is extremely light weight and can be worn as a layering piece or next to the skin as a base layer. Either way you choose to wear it, the top is highly functional thanks to incorporation of Polartec® Power Stretch® fabric which provides breathability and is fast drying; two key features in a base or mid-layer. The fabric combination helps keep your heat in, without making you completely sweaty. The fabric is also very stretchy and really moves with your every move. After numerous wash and wears, the top still looks new. As for durability during activities, I have yet to snag the fabric after months of heavy use.
The Jungfrau features a front zip that is a tad longer than most pull overs, which provides you, the wearer, with increased temperature regulation. However, when the temps plunge, the Jungfrau also features a higher collar that allows you to really seal in the heat. Many tops and jackets can rub on your chin when zipped up all the way; this was not the case with this top as it features a covered chin protector.
When you think of thumb loops, you typically think of a cut out of the fabric around the wrists to accommodate your full thumb with areas of fabric surrounding. This tops’ “thumb loops” are a little different; a small piece of fabric, approx 1/2″ wide encircles your thumb and really is a loop of fabric, to help keep the sleeves from riding up when on the move, for instance while climbing. I found these thumb loops to be a little small and constricting to my hands function. The sleeves of the top are quite tapered as you move to the wrist, therefore the sleeves moving around or riding up wasn’t really an issue for me at all.
As for the remainder of the fit, the Jungfrau runs a little small according to our American sizing standards. If you are wishing to use the Jungfrau only as a base layer, order according to the size guide. If you are hoping to layer over another top, perhaps size up by one. I tested a size medium and found the length to provide excellent coverage as it hit well below the top of my hips. The arm length was also more than adequate, which is often a trouble area for me. The body of the top was a bit narrow over my broad shoulders, however the chest and torso areas were a good fit. The top is available in XS to XL, as well as three bright color combos that utilize pink, teal, and orange as accents and the main body color.
Additional features included in the Jungfrau by Mammut includes flat-lock seams for a comfortable fit no matter your top layer or pack selection. The top also incorporates UPF 50, another great feature for when you are out in the elements all day. Mammut states that this top is ideally suited for classical Alpinism, mixed and ice climbing, and multi day expeditions. I felt that this top was ready for just about any challenge and look forward to throwing it on come backcountry ski season, as its’ breathability and warmth to weight ratio will be ideal for skinning pursuits.
