I have been an avid outdoor enthusiast for over 25 years.  I enjoy a variety of outdoor activities including mountaineering, day hikes, multi-day backpacking trips, river and ocean kayaking, back-country skiing, snowshoeing, mountain biking and rock climbing. I have climbed throughout British Columbia, the United States and when opportunity presents itself in Europe and India. I carry a wide variety of gear depending on the type and length of trip.  I am a search and rescue team member in the Southern Canadian Rockies and am part of the swift water, rope rescue and avalanche technical teams and ground search team.

The ColdPruf Classic Marino Crew and Pant and made of 100% Marino wool.  They have used a single layer jersey knit design utilizing 170 gsm or 5 oz silk weight.  The crew top has a modified raglan yoke shoulder, 7 cm (2.75 in) fabric cuffs and a 7.5 cm (2.95 in) drop tail.  The pant has a 3 cm (1.18 in) comfort waistband, gusseted front, 4 cm (1.57 in) back rise for fit and comfort and a 7 cm (2.75 in) ankle cuff.  Both the pant and crew top use the natural stretch inherent in merino wool for a snug comfortable fit.  The Merino State wool that ColdPruf utilizes is designed to provide a comfortable fit, keep the wearer dry and odour free and is flame resistant (always nice to know).  The label indicates that the base layers should be washed inside out with cold water and on the gentle cycle.  It also notes that fastidious people can iron them on the low setting and that they can also be dry cleaned.  

ThermaChoice System

ColdPruf has developed what they call a ThermaChoice system that is meant to assist purchaser with determining what they need.  The system provides a colour-coding system from cold to extreme cold and low activity to high activity.  The combination of the temperature range a
nd activity level directs the purchaser to the appropriate garment.  The ThermaChoice rating for the Merino Crew and Pant are listed for cold to very cold weather and medium to high activity level.   The rating system also links the product to the technology or design parameters used in the product.  In this case both the crew and pant use single layer engineering, moisture wicking technology and antimicrobacterial odor-fighting properties in the design.   It seems like a very handy tool for determining the best fit although, as with anything, personal comfort and internal heat generation will really affect this rating, still, very helpful.

Initial Observations & Fit

 The ColdPruf Base Layers look to be well constructed with consideration given to fit and comfort.  The arm length of the crew top is of a nice length for me, although the neck line and shoulders felt a little off when I first put it on.  I was not able to really figure this out as I had a bit of a reaction to the merino wool and had to disrobe in short order.  My skin is still itchy half an hour later and I must admit I am a little scared to put it back on.  I am hoping that after a wash or two or three that I won’t react to the wool otherwise this might be a very uncomfortable test period.  The pants were not nearly so bad and fit very well.  They are really snug and with a good amount of stretch which I anticipate will be a nice feature as they will go under almost anything with no problem.  They also seemed to sit nicely on the waist although I have not moved around much yet so will have to wait and see how they do once I get out into the field.  Overall they look to be a nice pair of base layers that I am hoping will keep me nice and warm this winter.  

Thank you to and ColdPruf for the opportunity to test the Classic Crew and Pant Base Layers.
