Bambool BT1 Base Layer Top 2016 - 2015 Review by A Better Ski

The Bambool BT1 Base Layer Top is a comfortable and functional light-weight base layer. It’s made with 68% bamboo (in the form of viscose), 27% Merino wool, and 5% elastane. This was my first experience with bamboo as a fabric, and I have to say that it’s very soft and quite comfortable. The combination of Bamboo and Merino also seems to work really well for insulation and moisture management. Merino insulates well when wet, but also does a great job of wicking moisture away from the body helping you stay warm and dry.

Tester: Matt

Size: M

Matt’s Specs: Sizing Info      

Fit: The Bambool BT1 Base Layer Top fits pretty true to size. I’m usually in-between a small and medium in base layers, depending on the cut. For the BT1 the medium fit perfectly fine, but is slightly on the loose side. If you like your base layer tight, I’d recommend going smaller if you’re in-between sizes. The arms are gusted, so it gives you a good range of motion, even in the tighter fit.

Features: The Bambool BT1 Top has a ¼ zip neck with a comfortable collar. The back of the zipper is lined with a layer of fabric, so you don’t feel the metal on your bare skin. Personally I still notice it’s there, and I much prefer a full pullover than ¼ zip, but that’s just personal preference. The Zipper does have a zipper housing, so it helps keep it out of the way of your facial hair or skin. The BT1 Top also has thumbhole loops, and is a nice touch for those who want the arms to stay in place. The loops are decent, but I did find them a bit tight, and after a long day in the top, I would notice a bit of soreness in my thumbs. I really don’t ever find the need for these loops, so I often just take my thumbs out anyway. If you do like them, I’m sure these will be perfectly fine. Of course the biggest feature is the bamboo, merino, and elastane fabric. It’s insulating, moisture wicking, soft, stretchy, and anti-microbial.

Bottom Line: The Bambool BT1 Base Layer Top works great as a light-weight base layer. It’s insulating and moisture wicking to help keep you dry and warm on the slopes. I’d probably opt for a heavier base layer on really cold days, but could see using this any day on the mountain as long as you have the right mid-layer and jacket. It’s probably one of the most comfortable feeling base layer tops I have used, and would be great if you value comfort as much as performance. I also really like that bamboo and merino are sustainable fabrics. I won’t necessarily say Bambool is overly environmental without knowing more about the processes involved in turning bamboo into yarn, but I’d say it’s something worth considering. Overall, I love the idea, and I love the fabric. If this came in a full pullover and didn’t have thumbloops, it would probably be my favorite base layer top.
