Seen here with the Atom LT jacket and Alpha LT shell, the new Beta LT pant is manufactured from Gore-tex Pro-Shell. It features an integrated belt as well as 3/4 length zippers to assist with donning and doffing. At 10.6 ounces when combined with the other two items, you get a cold weather package that weighs in at a scant 32 ounces total! Due to this lightweight construction, the entire set up packs down to a size smaller than a basketball. But don’t let the term lightweight fool you. I must admit I was skeptical when I first got my Alpha LT jacket. It felt so light I was worried it wouldn’t stand up to hard use but nothing could be farther from the truth. It is not only extremely well made and very strong, it also moves well with the body. Available in Crocodile sized Small – XX-Large from www.arcteryx.com/leaf.
