Base-layer bottoms run slimmer next to skin; rain/insulated bottoms use the same waist size with added room. If between waist and hip, use hip for relaxed pants and waist for fitted styles.
How to Measure
- Chest / bust Arms relaxed at sides, measure around the fullest part under the armpits, keep tape level.[12](@ref)
- Waist Measure around the natural waist at the narrowest point, usually just above the hip bones.[3](@ref)
- Hip / seat Stand with feet hip-width apart, measure around the widest part of the hips/seat.[2](@ref)
- Arm / sleeve With arm slightly bent, measure from center back of neck, across the shoulder, to the wrist bone.[12](@ref)
- Inseam From the crotch seam down the inside leg to the ankle; for boots, measure to the floor.[3](@ref)
- Hand / glove Measure palm circumference around the knuckles without the thumb; check model-specific cuff notes separately.
Use a flexible tape, measure over lightweight clothing, and avoid pulling the tape tight. For layering, remeasure while wearing your usual base layer.
Fit Types
Suggested Layering by Condition
General rule: a base, mid, insulated and rain piece in the same body size will stack for most conditions. If you regularly wear two heavy midlayers under a soft shell, size the soft shell up one. Never size a rain shell down to force insulation underneath—it compresses loft and reduces warmth.[6](@ref)
Should I size up for layering?
If you only add a base layer, stay true to body size. For fleece plus insulation plus shell, size outer pieces up one. Soft shells with multiple midlayers also benefit from one size up.
My chest and waist suggest different sizes—which do I use?
For jackets and tops, use chest. For pants and belts, use waist. For one-piece suits, choose by the larger of the two and note alterations.
Do these numbers match the garment tag?
No. Tables show body measurements. Actual garment circumferences vary by fabric stretch, style and fit type; check the product page for model-specific notes.
What if I am between inseam lengths?
Choose regular if within 0.5 in; choose tall if you wear hiking boots or prefer full coverage, short if ankle break is preferred. Untaped hems can be altered.
Do base layers shrink?
Merino blends may relax slightly when wet and recover after drying; synthetics stay stable. Follow cold-wash, flat-dry care labels. If between sizes in merino, choose the closer size for next-to-skin use.
Best For: Phone Storage
Built as a companion to your PRO G3 Bino Harness or used as a standalone phone case on a belt, the PRO G3 Phone Holder is the ideal storage solution for your phone and digiscoping accessories. Made from the same premium materials as our PRO G3 Bino Harness, the fabric is waterproof, quiet, and fleece lined—providing essential protection from the elements.
The main compartment features an Aquaguard zipper to keep moisture and dust out, while providing easy two-way access thanks to the dual zipper sliders. The interior is the optimal size for most small, medium, or larger size phones with a phone scope case and adapter attached. Featuring an interior mesh drop pocket, it stows and keeps a lens cloth, cleaning wipes, or small accessories organized.
The outer pocket stows and organizes your tethered rangefinder scope adapters, lens caps, and accessories, but may be used as storage for a compact rangefinder instead.
