You won't fit this hood over a helmet, and neither is it very satisfactory worn under one. This is a shame since the cut of the Krypton otherwise makes it well suited to climbing. In stormyconditions the fit can be closed right downusing two toggles, and there's a little stiffened brim to help the hood hold its shape in the wind.However these external toggles are fiddly to use with gloves or cold hands, while the brim unfortunately rides quite high, to leave a strip of forehead exposed. Overall I think the hood could have been better. The dense outer faceproves quite an effective barrier to wind. In cold, windy conditions close to zero degreesI've worn it over a baselayer, and felt comfortably warm and well-protected when on the go. To aid freedom of movement there's a little bit of stretch in the fabric, but not nearly as much as you'll get with something like a Powerstretch fleece. The face does feel very tough though, and while this has only been a short term test so farI'd be confident of its durability for rigorous uses such as scrambling. For three-season use the Lite-Speed is ideal. The weight is quite low, the features excellent. My only complaint is about the sizing. In earlier versions the Medium fits me. In the current one the Large is only just big enough. Any item not in its original condition is damaged or missing parts for reasons not due to our error There’s a little bit more stretch to this fabric than there is to Pertex Quantum, and this aspect, combined with well-articulated arms, makes the Lite-Speed much better-suited to climbing, mountaineering and running, in comparison to the previous generations.

We cannot be held responsible for goods returned to us but not received by us.With climbing and mountaineering in mind, the Lite-Speed also hosts a helmet compatible hood and two-way front zip to allow for harness use. We’re thinking fast and light alpine ascents where keeping the weight to an absolute minimum comes before full-weather protection.

I found that a size Large in the Lite-Speed Pull-On was a perfect fit for me. Whilst I can get into a medium, it was slightly too small for me so I sized up for a better fit.
