Size guide
Most Northbound products are one-size or adjustable. This guide covers our resistance bands and apparel (coming soon).
01
Resistance Bands
Our resistance bands are available in five tension levels. Choose based on your training goals and current strength level:
| Level | Resistance | Color |
|---|---|---|
| Light | 10 lbs | Yellow |
| Medium | 20 lbs | Green |
| Heavy | 30 lbs | Blue |
| X-Heavy | 40 lbs | Red |
| XX-Heavy | 50 lbs | Black |
Resistance values are approximate and measured at full extension. Actual resistance may vary slightly based on band length and stretch distance.

Our training backpack is designed with adjustable straps to accommodate a wide range of body types:
- Capacity: 28L

The backpack is one-size and fits most adults. The adjustable strap system ensures a secure and comfortable fit for torso lengths between 16 and 20 inches.
