Best T-Shirt!
December 06, 2010

I brought two mammut t-shirts, size M for my friend. He said this Mammut Logo shirt is fit well and comfortable on him and the other one, Mammut Tenny t-shirt is little bit smaller then this one.

Quality shirt

This shirt has soft cotton, quality stitching, regular sizing. What's more to say? A most comfortable and stylish shirt! The Mammut logo blends well into the shirt.

Cottony soft, yet outspoken
July 10, 2011

First, let me echo some of the other reviewers--order one to two sizes up! This T-shirt does NOT fit true to size. It runs small. Normally I’m a medium, so I ordered the large and had to return and reorder an extra large. The large was tight at the shoulders. If it shrank, I would have been out of luck. Second, the information on Altrec’s site, stating “Fabric: 70% Cotton, 30% Polyester,” is incorrect The Mammut Logo Shirt is made with bioRe® 100% cotton, meaning the the material is organically produced without the use of harmful substances, under humane conditions. The 100% organic cotton material makes it incredibly comfortable for running, climbing, or biking. Finally, this T-shirt allows wearers to flaunt their allegiance to a seasoned mountaineering company with planetary consciousness that creates innovative gear.

Pros: Build quality, flaunty

Great buy
August 09, 2011

Great quality t-shirt. Very comfortable for a hike or a casual day. The fit is smaller than usual so I recommend buying a bigger size than you usually wear


perfect choice
May 11, 2010

this t-shirt was a perfect choice. no regrets at all. i'm definitely buying another one.


Maybe the best T-shirt ever?
September 09, 2010

The quality of this shirt is first class, it just doesn't want to wrinkle and no fading of the design after several washes. I'm slowly going to get rid of all my north face shirts and only wear Mammut shirts from now on. I would pay easily $40 + for this shirt... the quality and feel is that good!

The shirt does run a little small, but overall the quality and details are great. There's a patch with the mammoth logo on the sleeve and Mammut printed across the back which you might not see in the images.

I love this shirt, but if you don't want a tight fit, better order 1 size larger. This is really a quality T shirt. Soft and well sewn. Buy one, and you won't be sorry. I'm traveling to Thailand this fall and this will be a hit over there. It's a 5 on a scale of 5. Just remember the fit and this is all cotton, so make sure you get one size larger.

Pros: Great design, Build quality, Ease of use

Sweet Shirt
May 05, 2010

Ordered one. The fit is so good, I'm ordering more in every color I can. It can be hard to find T's that fit my body well, but this one is possibly the best I have ever found. I have wide / muscular shoulders, a small waist, and an average to shorter torso length. This shirt feels almost custom made for me.

Great T-shirt

I like the T-shirt very much. The quality is fine. I have washed it about five times and it still looks like new. Great stuff from Switzerland!

Great Shirt, Runs Tight Though
November 23, 2011

This is a really cool looking and feeling shirt. The design is unique and the material itself is super soft. The only problem being for me that I have something of a belly and even the XXL failed to contain it. For medium and smaller guys this is a must have.

Pros: Great design, Build quality, Lasts forever, Performance, Ease of use, Great value

Even non climbers who have no idea what Mammut is think this shirt is stylish! Fits great, is extremely soft and comfy. I would wear it every day if I could get away with that!


Nice shirt
October 04, 2010

I like this shirt. It does what it is supposed to do. It let's people know that I love the brand and it looks cool. The only problem with this shirt is it will shrink on the first wash/dry so I would go one size up if you are at all questioning going one size up.

Great Shirt

Excellent Color
October 19, 2010

I bought this tee in the oasis color, and it is a lovely shade of leaf green. The quality is excellent, and both the fabric and logo have survived multiple washings. The shirt fits true to size, and feels good against the skin. An excellent purchase.

A splendind, well made T
March 28, 2011

This t-shirt takes wash after wash like a champ and never fades, I'm blown away by the quality. I only wear Mammut t-shirts because of this and the price is a steal considering these fancy designer shirts you see at the mall that look stupid and fell like they're made out of recycled paper and cost $50 plus! If I could only wear one t-shirt the rest of my life.... this would be it!

Mammut Classic
July 23, 2010

Previous versions of this shirt are some of the longest lasting t-shirts I have owned. With regular use and washing the color and silk-screening have held up well. Amazing! The fit (L) is perfect for my 5'11" -175# frame. A slim fitting shirt, but not too tight and best of all it does not have the lame, wide, low, loose neck found on many of today's Ts.

Great shirt
December 28, 2010

I bought this shirt in a medium cause thats what i normally wear. Sadly, i had to send it back for a large. these shirts do run a bit small. so order a size up.


Great T-shirt
April 04, 2010

This Mammut T-shirt is great. The fabric is high quality and feels pretty good. The fit is perfect. FYI: I am 6 and about 175 lbs and L fits me well. As shown in the picture, the front of the shirt is a big Mammut logo. On the back, there's a line of letter "Mammut". I ordered the black version and the letter on the back is red. There is also a embroidered small mammut lolog on the left sleeve, which is my favorite. The small logo is the same as the big one. The difference is that the big one in the front is printed but the small one is embroidered. Overall, I like this shirt very much and would highly recommended it to you.

High Quality, tight fit
October 02, 2011

Very comfortable organic cotton shirt. As other reviews have said it runs small. I took the risk and ordered my size (XL) it is not as snug as other brands that often run small. If you have a beer gut like me you might want to order up otherwise you will likely be fine with your regular size.

Pros: Build quality

Great Shirt! Quality material and good fit.

June 03, 2011

This shirt was definitely a great buy. I'm always a little hesitant buying shirts online due to the differences in fit, but this one is true to size. Not excessively long in the torso and not too tight in the arm area either. Build quality seems very good, comfortable fabric that's surprisingly lightweight. Color has remained vibrant after several washes as well.

Pros: Great design, Build quality, Great value

Buy big, it shrinks.
November 24, 2010

Great shirt, soft material. Tag on inside was irritating the heck of me when i first got....washed and problem went away. Though shrank quite a bit when i did wash. Happy with it, hope Altrec keeps stocking all the colours at this great price point.

Great shirt, will shrink
December 18, 2011

love everything about this shirt, I bought 3 different colors. however, they will shrink A LOT! I like wearing my shirts relatively tight so I ordered the large. after washing once it shrank to an unwearable size. I recommend ordering a size up for a perfect fit.

Pros: Great design, Build quality, Lasts forever, Cons: shrinkage
