How to Take Your Measurements
1. SLEEVE MEASURE
Bend your elbow and put your hand on your hip. Measure from the center of the back of your neck, along the shoulder and down the elbow to the wrist bone.
2. CHEST SIZE
Take measurement under armpits, around fullest part of chest and shoulder blades.
3. WAIST SIZE
Measure around where you normally wear your pants, keeping the tape measure a bit loose or putting one finger between your body and the tape measure.
4. INSEAM
In a standing position, measure from your crotch to where you want your pants to end, breaking at the top of the shoe in the front and just above the heel in the back.
5. GLOVES
With hand partially closed, measure over the knuckles, around the hand, excluding the thumb.

FIT GUIDE
SITKA assigns fit descriptions according to how a garment is intended to be layered.
SITKA Fit Descriptions
Check the fit description for the item you are considering. Performance, Standard and Expedition fits allow different amounts of layering.
P/F - PERFORMANCE FIT
Designed for minimal layering. Whether an early season piece or already insulated this garment fits to prevent inefficiencies in heat retention caused by dead space
S/F - STANDARD FIT
Designed to accommodate layering for more versatility from early to late season climates.
E/F - EXPEDITION FIT
Designed for maximum layering in the worst conditions. Cut roomier to accommodate additional layering underneath.
Sizing information: SITKA Gear. General charts, measuring instructions and fit descriptions checked October 6, 2026. Product-specific sizing may vary.
